Modularity and the AR style rifle have gone hand in hand since the platform’s inception. These guns were built to be assembled like Legos, and that’s how we’ve treated them ever since, building and rebuilding around the solid core of the receiver. As the guns have evolved, they’ve become smaller, lighter, and more reliable. We’re used to seeing fly-weight AR-15s and one-off design concepts. Now the same thing is happening to the .308 AR platform and DRD Tactical is leading the way. Their new take-down M762 is challenging the basic perceptions of the overgrown AR.
The M762
I’ve never really been a big fan of the .308 AR rifles. I prefer lighter, more compact rifles for close quarters work. So I was a bit skeptical when I was presented with the DRD Tactical M762. The gun just didn’t make sense to me.
Why would anyone want an heavy rifle that could fit into a small suitcase? Wait–that makes me sound like a gun-grabber. That’s not what I mean. I own an AR that fits in a briefcase–and I don’t have any issues with that one. The bigger rifle, though? Can it be broken down small enough to fit in a compact case and still retain any of the characteristics of a hard hitting, full sized, big-bore battle rifle?
Or would the M762 would be some elaborate proof of concept–a gimmick? Gimmicks don’t usually shoot very well.
I’ve had the gun for a few months now, and have drug it to the range on multiple occasions. I’ve even taken it on a few longer trips, and the compact size has a clear appeal. I understand it now. There’s nothing about this gun that feels like a proof-of-concept. And at the end of this review, I’m going to have a hard time letting this gun go.

Design
The M762 is a capable rifle. The gun provides solid accuracy and unquestionable reliability. It is highly concealeable–something I’ve never said about a .308. Its safe to say this recipe has never before been available in a package this small. Broken down, this rifle measures in at an astonishing 17 inches long and 5 inches wide. All of these rifles ship in an 18-inch hard case. The case has room for the broken down rifle, a red dot optic, magazines, a cleaning kit, a suppressor, a sidearm and pistol magazines. Fully loaded, the case gets heavy–but the peace of mind that the fully loaded case gives you is worth every ounce.
The forend uses Magpul L4 Panels.
A weapon system is only as strong as its weakest part; thankfully theM762 is built like a tank. Comprised of billet upper and lower receivers and a hammer forged barrel, this gun leaves nothing to be desired. When picking up the rifle for the first time you will instantly notice the quality of the workmanship and the attention to detail. Every angle, every line, every detail has a weight saving rational behind it, yet the M762 is still robust enough to handle the heavy recoil. The assembled rifle comes in right under the 9 pound mark, a weight that most of these rifles blow right past.
The M762’s defining feature is how it breaks down. The hand guard and barrel can be quickly and easily removed from the rifle. Assembling the rifle is very easy, In fact all you’ve got to do is lock the bolt back, slide the barrel and gas tube into place, hand tighten the barrel nut, slide and lock the handguard into place and you’re done. Then give it a quick function check. In a matter of seconds, that small 17 inch package is now standing tall at 35 inches and ready to rock.
I can’t even begin to explain how dubious I was about this feature at first. The .308 produces serious recoil energy. Would the hand-tightened nut eventually work its self-free? I don’t want to shoot a .308 through a wobbly barrel. On my first visit to the range, I assembled the gun fired 40 rounds down range as fast as I could then quickly took the gun down to examine the tightness of the barrel nut. The gun held together like a champ and was still easily taken apart–hot or not. After multiple range trips, I can confidently say that this system works. The nut stays in place perfectly. Once assembled, this gun has the rigidity you’d expect from any .308.
Shooting the M762
A rifle of this size, weight, and caliber is sometimes hard to handle on the range. A .308 can punish your shoulder, hammer on your eardrums (even when you’re wearing hearing protection), and the weight has a way of wearing you down. Oddly enough the M762 is soft shooting, moderately quiet (from the shooter’s end), and very well balanced.

The gun produced decent groups. A combination of weight, rigidity, and a very impressive muzzle device keeps this rifle shooting flat and fast. The rifle is extremely stable. Swinging from target to target can become challenging as fatigue sets in. The gun has a stainless steel barrel with a heavy profile. As I got tired, I found the gun’s momentum carried the barrel slightly wide of targets as I swung from one to another. It isn’t a featherweight AR-15, for sure. But deliberate, controlled movement makes the weight manageable. This isn’t unique to the M762. Any heavy rifle designed for close quarters work will have the issue.
Groups at 100 yards were consistently between 1.5 and 2 inches. Still—consider the obstacles you face in a design that allows you to quickly remove the barrel. When I think of it that way, I have to cut the M762 a bit more slack. There are a lot of .308s (ones that don’t come apart) that won’t shoot groups this tight.
A red dot on a .308 may seem like a missed opportunity, but these heavy guns have their place in close quarters combat, too, and the extra speed gained is an asset.
Even at 2 inches, the groups prove the rifle to be effective. I ran a Nightforce 2.5×10 on the gun for accuracy testing. Yet the scope didn’t fit into the foam the hard case is supplied with, so I found myself relying on the Primary Arms Micro Dot for the majority of the review process. The Micro Dot allowed for realistic 4 inch groups and much faster target acquisition. In the short distances available here in the backwoods of Virginia, the red dot style optics are a natural fit.
While I’m fine with the performance of the gun, I will add this about its philosophy of use. For close quarters, this rifle is superb. Even at typical southern hunting distances, the compact design of the rifle makes it ideal. Yet one big potential of rifles like this is the long range stopping power of the .308. At greater distances, the M762 isn’t going to compare favorably with some bolt-action rifles. But the accuracy is on par for what you’d expect from a semi-auto.
The DRD guns are made in Georgia, a state with a strong gun making industry.
Ergonomics
Feeding from Magpul magazines, and dressed with Magpul furniture this gun just looks the part. Beyond looking the part the gun feels the part. The slim aluminum handguard allows for a high C grip on the weapon, leaving no need for forward attachment or grips. If you do feel the need, the hand guard does accept Magpul L4 panels, making attachment as easy as turning a few screws.
Beyond its creature comforts, the M762 has a beveled magazine well, and milled trigger guard, and the gun has standard AR controls. Nothing is ambidextrous, and nothing is overly fancy. Anodized aluminum and polymer is all you get, and for the majority of us, that’s plenty.
The rifle doesn’t ship with sights. This seemed kind of odd to me. If I am going to spend $3250 on a rifle, I would expect some Magpul BUIS, at least, to ship with the gun. But maybe that’s just me. The good news is that the cut foam case does have area removed to accommodate sights. There is also a spot to hold a small red dot optic. The only problem I see with this is you must remove the optic from the rifle for storage in the case.
The Standing Question
Let’s wrap this up with this. In the saturated black rifle market, the M762 truly sets its self apart from the heard both in price and in function. After all of my time with the M762, I’m convinced by both the gun and the compact take-down design. Yet the price is really substantial. $3250!
If we were just comparing rifles, I’d say there were systems on the market that represented a better value. But we’re not comparing apples to apples, because none of those break down into such a small, portable package. And until they do, they can’t be compared.
So how much is this feature worth to you? If you can stomach the hefty price tag of the M762, it won’t disappoint. If you don’t need a take-down .308, and just plan on putting the assembled rifle in your safe–then this may be a harder decision.

Two layers in the case. If you did want a larger optic, this bottom layer could be repurposed for a scope.
[/one_half][one_half_last]
The muzzle device is long and works to mitigate recoil and redirect sound.

Not much room for large optics. But the case its super small.

What model is the case? I am trying to replace mine that was stolen.
If I could get the upper and barrel nut (assuming they are the only special items) would be all I need.
Everything else picked and installed by my personal preference.
Offering a pricey gun that is unique and special, by all means do so, but at least offer the unique parts alone to those of us who only build our own guns.
All too often, the price on every other part on a gun like that, is jacked up way beyond what some of us think is reasonable.
Actually you can buy just the parts you need, but you also need the handguard as it is part of the quick release system. I actually bought the 5.56 version and have since purchased a 300 BO barrel and spare barrel nut to work with the weapon as well. It is very versatile and useful set up. I also purchased the case with cutouts for the rifle in the top and my glock and mags on the bottom. Very handy for a quick exit scenario.
Look just because you can not afford the package offered and reviewed in no way diminishes the product. There are many rifle and handgun packages I can not afford, but there are plenty of people that are above me that can. Just because those weapons have to stay on my Dream/Maybe/On day list doesn’t take away anything from the quality or usability of the weapon in question. Just as there are many weapon systems I can not afford, there are also many I can that perhaps others can not, and so the saga goes on. I am not fortunate enough to have a DRD 308 in my inventory, but I do have there DRD take down 5.56 in a beautiful Nickel Boron finish. The rifle is very nice and shots much better then the 308 that was re-viewed here, but that may be an issue with the ammo cued too. I like the DRD take down design so much I built a 300 BLK with there stock and quick relies feature, it too is a great rifle that most would be happy to own and shoot. If you look at the take down market, there are only a hand full of manufacturers out there, and the pricing is evenly higher then that of a non take down rifle. Think about it, first there is much more R&D that goes into a rifle like this, especially if it is to function, shoot and keep it’s zero! This drives the price point up, which also will effect the total sales of such a rifle, this causes the final sales price to be higher then many of the rifle most would consider. The fact that you now have the ability to covertly carry a rifle into a place without detection, is what draws the eventual owner to the rifle. Add in the want for a easy to assembly and quick to dis-assemble rifle, the ability to keep it zero, and the high quality and care that went into the manufacturing of the weapon and you arrive at the DRD line-up of quality weapons. Are there cheaper 5.56 rifles? Yes, you can fine cheap stuff anywhere, Wal-Mart or your locale gun shop…but you will not fine the better stuff at just any place, most likely for the DRD line-up you will have to travel to the better places that handle guns or order it from a large on-line retailer like Eurooptic or similar dealer.
Most of my collection of rifles I built myself, so there was no name brand involved in the purchase, just quality parts from known sources. Most assume something built at home can not be as good as there cheap to mid price range rifle purchased from a place of business, but I strongly dis-agree. I would say the average cost for one of my home builds in a standard AR build, meaning 5.56,300BLK,6.5Grendel, 6.8SPC, 7.62×39, 50 Baeo builds like that, run about 1400.00 less optics. Again average, if you build a long barrel 6.5 Grendel with a quality Alexander or Sheilen barrel, then you will have a few dollars more in it, same goes for all the calipers but you get the drift. Just as if you start that build with a Billet Upper & lower or a DRD upper and lower Take down, you will have more in the rifle and exceed the average cost. It’s not a game about who has the most, or even who spent the most, it should be about getting the most gun you can for the amour of mosey you have to spend. I have many rifles, some are fun to shoot, but are not that accurate or attractive. Some are very accurate but not fun to shoot. Most would do in a pinch, and all will kill what you aim them at, does it matter if one is .25 MOA and the other might be 1.5MOA? At several hundred yards they will both seek what your aiming at. But in a hurry, at time when it really matters and you have to make that decision about which rifle am I going to take with me and which ones do we leave, knowing this is the rifle that will keep me alive and provide food, security and stealth from those that wish to do you and the ones you love harm…I know that DRD take down will not be left at home, nor will my SIG 556 Swat or the silencer for both.
Love the review. Was never a fan of a ar10 just seamed too bulky to me. A dealer friend of my ordered one to sell. Evertime I went to his place I couldn’t help but pick it up and handle it. He had ordered the pistol with 12″ barrel. Well I just had to have it. Bought a ubr stock and aimpoint comp m4. And when my lovely $200 stamp came back and I assembled with ubr oh my god did it a make a difference. To be honest it was a little front heavy with a sig brace but the ubr really balanced it out. I’ve only took it shooting once. Sighted it in at 50, at 100 yards from a bench rest it will shoot .5 moa (tear up a single hole) and that’s with a 1x red dot. Next loaded it with ebc subsonic ammo and c&s suppressor and point of impact dropped 4 inches and spread to a 1.0 group. Now to be honest shoot hot loads it is alittle bit of a beast. But the quality of every part and expectally the nickel boron bolt and stainless Walther barrel are just great. Now keep in mind I have plenty of 2k plus ar15 in 233 and 9mm and sbr ps90. And I was alittle weary of spending 2500 on a ar10 then stock, optic, bcm charging handle, and of course 200 to the atf. But I do love this thing. If you ever get a chance to shoot one I’d advise doing so before passing judgement becomes of the price. Now the one place I believe I needs improvement is the trigger. It is alittle long and heavy but it’s just a standard milspec model. Have a 2 stage on way for it now
Rather buy a PSA AR10, A nice scope, free float tube, bipod and ammo. The ar platform is already takedown. Just pop 2 pins and the rifle is smaller for storage. I can already fit my broken down AR into a tennis bag.
Numerous buyers have encountered problems with rounds not feeding into the chamber, difficult round extraction, and extractor scaring cartridge rims with the PSA AR 10 carbines. Also problems with the company repairing the problems have been discussed in forums.
I am one of those buyers with problems. Good luck, I hope yours works well.
I carried the M14 in Nam and I believe that and GOD is why I came home.
Vienam 1968 and 1969 love you GOD – 308 M14 – USA

I could not see spending $3250 on one gun when it’s price exceeds what I paid for my entire collection thus far!
I have a Mosin Nagant in 7.62X54R
A Wincheater model 70 in 30-06 sold by Sears as a model 53
A Remington 870 clone called a Hawk 982
A Marlin model 81 in .22LR sold by Sears as a model 43.
A 1911 milspec .45
A 1911 accessorized 9mm.
And the most expensive is a SIG in .380 no less!
I’d say you have all the bases covered and that’s what it’s all about, isn’t it.
I’ve never been one to purchase high dollar guns just to have them sit in the gun safe and brag about them either.
There are better rifles in that caliber for far less money. The ability to break down and pack into a small case must be a high priority to someone to justify the price.
I was in the service a few years ago. I still think the M14 was the best battle rifle ever. Shot in the LeClerc matches, various targets from 100 meters to 400 meters with iron sights. The best! Learned how to shoot it. Heavy unwealdy sometime, but a shooters weapon. Not like Ar15 ect, all they are is see how much shit you can throw on the wall and hope you hit something. You only need 1 shot if you know how to shoot
I’m interested in hearing some points of view concerning the person who carries more than one gun. I, for instance, carry four(4) rifles in different calibers.
My inventory consists of a custom built Windham Weapon in .223 Rem, a Remington 770, in .300 Win Mag, a Mauser, in .308 Win, and an AK 47. The first three have scope mounted optics and the AK has a Red Dot optic sight.
I do not worry about being under gunned or what particular rifle I need today. I have all four at hand and ready for action.
I carry ten but I haven’t been able to make it to the front door of my man cave yet with all that manly weaponry and ammo strapped to my pack. Currently I’m taking ZUMBA lessons and hopefully in six more months I can make it to the creek for a drink of water without any beavers splashing mud in my face.
What a gip!! You get me to believe you would drive to the woods, walk up a tower, put together a rifle and then take it down without firing the thing?!!! What part of “why would you do that?” do you want me to ask? If I was even remotely interested in buying one, instead of say a Springfield M1A1, which has some class, this video would not have helped me decide. Next time shoot a few rounds. How do I even know if the thing will shoot?
$3250 for this? Seriously? How is this cost justified? Also a 1:12 barrel in a 16″ or 18″ using .308/7.62? If it was 22″ or longer I’d understand that.
How hard would a lock-out be which prevented releasing the forestock with a round still in the pipe? That way the weapon could not discharge while someone is unscrewing the barrel. At the million dollars a weapon they are charging, there should be something akin to added safety for the plink-dinks who need to have one…
Too much for my pocket book. I’ll stick with my M1-A! I can get better groups than he’s getting with it, and that’s only with Natl. Match sights. I also have a Natl. Match M-1 Garand that “ain’t” bad either. I paid a lot less than $3250 for the M1-A or the M1 Garand. I’m a happy shooter!
Nice concept.
I like what I see.
But instead of bending us over and seeing what we’ll pay for it because it’s exclusive,
they should be like Ruger ( TD .22 ) and keep the price reasonably low.
They would sell 100 x more of them.
Gaffers don’t care about their customers as much as they care for their money.
No real value, and a big marketing mistake.
I would like to know where he got the back pack?
I think I could break down any platform and fit it in there.
There is nothing new about this. LWRCI.com did this years ago with their REPR. They had 10″, 16″, and 20″ barrel configurations. Not only that but LWRC rifles are tits on accurate even with plinker ammo.
.308 obsolete…BAHAHAHA. Obsolete like water, air, and the wheel. Maybe when the ATF bans it.
Did I miss something here? A 14″ barrel with a standard stock sounds like a SBR which needs an ATF stamp. Why not just buy a good 14″ upper from a company like Hardened Arms and use a x long KAK pistol brace. This would qualify as a .308 pistol and avoid dealing with Obama’s gun commies and their greedy senseless gun laws, PLUS you can build one for UNDER $1500 case included.
take down?
Sounds like a great concept if you travel quite a bit with your rifle. The price point is probably above what most people would be willing to pay, but then again, I’ve seen quite a few shooters/collectors shell out cold hard cash for the latest gimmick only to have buyers remorse later and then to be further let down when they couldn’t get a decent value for the rifle/pistol when they went to trade for something new. The idea of what is affordable varies from person to person but 3k is by no means, just a drop in the bucket.
I’ve always wanted an AR 10 even though my Springfield M1A Loaded and Weatherby Mark V Super Varminent Master work just fine.
When I retired my wife brought me a DPMS LR .308 the dealer sold to her at his cost since we have been doing business with him for 30 years.
I’ve put thousands of rounds of ammo from the cheapest questionable imports to expensive American match grade through this rifle and have yet to have a failure of any sort. It is a good solid, accurate rifle and for my purposes, bench rest shooting, it works just fine and it didn’t cost 3k. Granted I wouldn’t want to trek 20 miles into the mountains or woods with it on my back but here in central Indiana that isn’t an issue.
Maybe we’re being silly about a weapon’s weight. When I was in, I humped a 203. Being part of the heavy weapons section, I also carried M-60 ammo, tripod on top of my 223’s and 40’s. That was heavy. With my current AR15 battle ready it’s put on a lot of weight. I don’t worry if it will keep me alive, weight(within reason), don’t matter.
I’d love to have one. At $1,999. I might be able to afford it. At $3,250. it’s a bridge too far.
Unless you’re a survivalist (with money to burn) and justify the use of the .308 round by its ubiquitous availability then such a stiff price on a relatively obsolete caliber despite the ‘coolness’ of the tricked take-down, (which by the way is probably only one second faster than i can ‘take-down’ any standard AR platform to separate into two pieces for compact transportation, what’s the main advantage over say…a regular compact 5.56 AR platform with 14 inch match grade barrel and a pinned/welded Phantom or other significant flash reducer bringing it out to 16 inches allowing it to fit in even a smaller case and be lighter when broken down and will be more accurate than this one, and just as effective in virtually most, if not all CQB applications, for all pragmatic purposes…
…and for a cost of less than 1/3 of this thing?! And if one insists upon being ballistically anal, then one can get a bit thicker case and add the 6.5 Grendel upper, just in case one ‘needs’ to snipe out those Zombs at 600 meters or so with more kinetic authority? The addition still bringing in the total package under the sticker shock of this baby here?
7.62 x 51 Obsolete? Funny, still being used in Afghanistan as the EBR (Enhanced Battle Rifle), just an M14 in a new stock with optics, they use it because it does not jam like AR’s are prone to do and has the range and knock down power that the AR 15’s don’t have; and it does not have to be cleaned after every round. I have always opined that redirecting dirty gas into your chamber is the most inane idea in the world.
I believe any comparison of .308 to .556 is a moot point. I am interested in this type of weopon for one reason only. I only want to carry and stock one caliber of ammo. I will use my Rem 700 for the long shot, but having a close quarters rifle in the same caliber has a lot of advantages. The take down feature of this system, while nifty and cool, doesn’t outweigh the value of my Larue compared to this gun. I can buy more ammo, or upgrade my optics for the difference in price. The .308/.762 rifle in my mind isn’t an outdated round based gun. It is just coming into it’s own with multiple offerings just now popping up. They wouldn’t invest in the tooling and R&D if there wasn’t a market or a bunch of gunowners wanting one. Not to mention, I’ll take a .308 into a firefight over a .556 any day of the week. When I pull the trigger on something, I want to take it down. One shot, one kill. Not something I can guarantee with a .556 when hunting deer, moose, elk etc. Throw any kind of distance into the mix, and well, there is no comparison.
Obsolete ? Not hardly !!
What it is, is a step up from a 5.56, and in civilian mode a sporting round that will take any and all north and south American land game including the big brown bear as long as you have the time to pump three or four rounds in his kill zone, which is about two seconds in semi automatic mode.
Jaguar, Puma, Moose, Elk, Mountain Goat, Feral Hog, Mule Deer, Black Bear, Black tail or White tail Deer …the list goes on and on..
Not only are you a dork but you are such an ignoramus. 308/7.62×51 is not outdated or obsolete at all. To all you others who compare it to the 5.56 I call you ignoramuses as well. Bullets are tools, every caliber has its place and purpose. You need to find your place and purpose, then choose your tools accordingly.
C’mon guys! The Ar-15 w/556/223 was chosen for a specific theater, specific time, specific opponent. It was first intended to be an Airforce survival tool. Next the Army liked it for it’s multiple hit characteristics and ability for the troops to carry more ammo. For some reason all that was forgotten about. All of the following performance improvements, 6.8 included, were to get it back to Gene Stoner’s original design. AR-10 7.62/308win. One 308 to the vitals, up close will do the trick. Most walls, or other household items will have little effect. Even with heavy clothing, commie type chest rigs, heavy vegetation and longer distances have little effect on it’s effectiveness. I’m no expert, but I am not aware of any 308 system that is as controllable as the AR15 under full auto. I’d love to see how an AR10 does with the proper muzzle-brake/flash suppressor.
OBSOLETE CALIBER ???, THE 7.62 / 308 , AND THE 223 / 556, THATS A REAL SHOCKER TO ME FIRST IVE HEARD.
SO WHAT ARE THEY BEING REPLACED WITH ????
PROVIDEING THOSE WASHINGTON NAZIS ALLOW US TO HAVE.
Looks like a nice package but I recently purchased a Palmetto State armory P-10, which is an AR-10 type carbine.
The price was good but on delivery, and first time at the range I ran into failure to chamber properly so many times I would have been stomped to death by an angry moose if my first shot wasn’t dead on.
I sent it back to the factory and they did something and sent it back in about a week.
My second attempt at the range was much better but It still has a few failure to properly chamber round problems.
My extractor which has a heavy spring, grips the case rim too tight, which other buyers say is the problem with the round not chambering correctly. ( they recommend replacing the spring with a AR-15 extractor spring)
My extractor actually mangles the case rim sometimes and this is something that needs to be corrected.
All in all when I get this problem fixed I will be satisfied with the rifle as it shoots well and accurate and the recoil isn’t bad at all.
Any suggestions will be received with thanks as long as they aren’t childish taunts.. Happy Shooting !!
Could be that the throat was improperly machined allowing the round to seat too deeply thereby giving your extractor a devil of a time extracting the spent casing.
If you are using steel cased cartridges they will often expand which also makes extraction difficult. More so in bolt guns than semi-auto’s.
I wouldn’t try to much to fix it on your own. You paid good money for a product and if it isn’t working properly send it back and ask for a replacement or a refund. If you get a hassle contact your state Attorney General’s office and file a complaint.
Thanks for your input, but I am mechanically inclined and tinker I must do.
Hey Joe you may be having a gas port problem if it is ripping your shells apart , or a buffer issue, Try a different buffer spring and buffer and if that does not fix it try a adjustable gas block you may be getting to much gas, by the way I have had major issues with the quality control from palmetto sate armory so try and go through some else next time I bought a upper that had the barrel epoxied to the upper receiver, the barrel didn’t have the pin that goes in the slot on the upper so they glued the barrel in I fought with them for over a month before they were willing to give me a new barrel I had to have a gunsmith and the shop I bought the upper from ream there ass before they would do the right thing. Good luck try the syrac or odin works gas block…,
I’d like to see 10 shot grouping with Match ammo that the rifle likes at a 100 yards in a vice, then take down repeat, take down repeat to see if it holds zero. Also who runs a micro on a ar10 other than function test, I’d rather run irons and utilize the sight radius, but hey looks like you weren’t concerned with precision or accuracy.
