We’ve seen lots of chassis rifles in the last several years, but MK Machining has further refined their chassis with significant weight reductions, performance enhancements and they’ve expanded their compatibility. Oh, and it’s a bullpup.
MK 2 Bullpup Chassis, by MK Machining
The basics of the MK 2 is that you can take any Model 700 action (long or short) with a barrel and drop it into this bullpup chassis. On average, you’ll end up reducing the length of the rifle by 12″ and you’ll make it much more balanced as well.
It works with both left- and right-handed actions (just swap the cheek piece on the stock). New this year, the chassis is compatible with Tikka T3 actions, too.
But it’s not just shorter. The stock is completely customizable to your body. The handguard has M-Lok slots and an ARCA base rail, and there’s a 20 MOA Picatinny rail on top.
The trigger linkage has been improved this year, as well. The operating rods are now encapsulated for enhanced performance. Timney makes Calvin Elite, the adjustable single-stage trigger which can range from 4oz to 2lbs pull weight. The whole chassis weighs just 3.5lbs.
The whole chassis is 6061 aluminum with steel and bronze components. The grip is printed by MK Machining (they’re one of the largest 3D printing houses in the country) and is compatible with standard AR grips, and it’s compatible with AICS mags. They can customize the finish in Cerakote, hard anodized, or others of your choosing.
MK Machining is taking orders for the MK 2 chassis, and it’ll cost you around $2,000.
Left handed shooters need not apply.
Although it appears to be finely machined, it answers a question nobody asked.
Luckily it takes right or left-handed actions and the safety is both relocated and ambidextrous. We have delivered batches to special forces groups and many hunters, with significant LEO interest. They seemed to have asked, and enjoy the modularity and compatibility with their existing rifles over DT 🙂
Speaking on behalf of other lefties, we’ll pass on this one.
It’s appears to be beautifully machined and of high quality, but it seems to be answering a question nobody asked.
Hey guys, Tyler, owner of MKM here.
More than happy to answer any questions:
With a 60° action (as shown here) you can certainly keep your head down and work the bolt. Plenty of video, but if you can touch your ear you can work the bolt. These 3 lug actions work nicely, you can keep your head down with a standard 90° bolt, but very easy with a 3 lug. It is about half a second slower than a typical bolt gun, and if rapid followups are the main goal, a precision bolt gun is likely not the best choice.
Whether you blow up an action 6″ or 18″ in front of your face, you’ll have a bad time. Luckily modern actions are incredibly safe, have pressure relief paths, and if you truly blow up an action a foot of difference likely won’t change much. The cheekpiece is fairly beefy aluminum however to catch any gas if you blow a primer, etc.
Wow, this is an excellent piece of machining. I personally enjoy bull-pup designs because of their balance, and more compact form factor. I like the trigger transfer mechanism on this stock. Most of the commenters are probably older individuals who may lack the ability to touch the front of their shoulder or lack the strength to move the bolt at that position. Anybody complaining about how fast the action is, is really not seeing that as a weakness in any bolt action. I like that the cheek piece can act to protect the shooter from an exploding chamber. No other firearm really has such a shield. You are never going to get a majority to agree on anything, but at least this will be attractive to that small niche that will appreciate it. Thanks
Two things I don’t like about bullpups, I don’t like a 60,000 psi explosion going off a 1/2 inch from my head and their slow to chamber another round because you have to take the weapon completely off your shoulder each time you chamber a round. I built one on a SSP rotary action over 20 years ago and it was chambered for 243 with a 21 inch barrel and was very short and compact but cumbersome to operate and that rotary action was a lot faster to work than a bolt, even though it was a single shot but I cringed everytime I fired it knowing what was going on right next to my eye.
Wouldn’t it be difficult manipulating a bolt so far behind the trigger?
Hmm , Bolt action right by your shoulder. Gonna be hard to work that bolt . Methinks Bullpup action great for semi-autos, not for bolt action. Just my opinion.
