Ballistically speaking, you can compare the two as follows. The AR in .308 fires the .308 Winchester cartridge while the AR-15 fires the .223 Remington (or 5.56 mm NATO) round. To provide an approximate comparison between the two, we need to look no further than my friend Andrew Chamberlain\u2019s world famous <a href=\"https:\/\/www.cartridgecomparisonguide.com\/\" campaign=\"CartridgeComparisonGuide\" target=\"_blank\" class=\"clickTracking\">Cartridge Comparison Guide<\/a>. If we look at kinetic energy, which can be loosely defined as the destructive power of a given cartridge, we find the .223 Remington delivers somewhere in the neighborhood of 1,280 foot-pounds of energy. \u00a0That\u2019s for an \u201caverage\u201d 55-grain load moving at 3,240 feet per second. An \u201caverage\u201d 150-grain .308 Winchester bullet, with a velocity of 2,850 fps, delivers 2,704 foot-pounds of energy at the muzzle \u2013 over twice as much!<\/p>\n<div id=\"attachment_65098\" style=\"width: 1034px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/R20FFTM-308.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65098\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"wp-image-65098 size-large\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/R20FFTM-308-1024x216.jpg\" alt=\"This rifle is an optics ready flat top configuration. \" width=\"1024\" height=\"216\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/R20FFTM-308-1024x216.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/R20FFTM-308-150x32.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/R20FFTM-308-400x84.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/R20FFTM-308-768x162.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><p id=\"caption-attachment-65098\" class=\"wp-caption-text\">This rifle is an optics-ready flat top configuration.

Just be aware that there is not necessarily complete parts interchangeability between .308 AR \u201ctype\u201d rifles from different manufacturers. Also keep in mind that, due to the much larger cartridge size, key components like the lower receiver, bolt and carrier group, and magazines are all different than their AR-15 smaller siblings.<\/p>\n<div id=\"attachment_65099\" style=\"width: 1034px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65099\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-large wp-image-65099\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1-1024x496.jpg\" alt=\"Just for scale, the Windham Weaponry rifle is shown here (top) with the Armalite M-15 we recently reviewed. \" width=\"1024\" height=\"496\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1-1024x496.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1-150x73.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1-400x194.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1-768x372.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-1.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><p id=\"caption-attachment-65099\" class=\"wp-caption-text\">Just for scale, the Windham Weaponry rifle is shown here (top) with an Armalite M-15\u00a0in 5.56mm.<\/p><\/div>\n<p>Windham Weaponry is a relatively new company \u2013 sort of. Founded by many of the folks behind the original Bushmaster company, Windham regenerated in 2011 after Remington moved the Bushmaster operation to New York. When his non-compete agreement with Remington ran out from the 2006 purchase by Remington, Bushmaster founder Richard Dyke gauged interest among former employees in the Windham, Maine area about the idea of rebuilding a new company. Interest was high, and the company was again producing rifles within months. The bottom line is that the Windham folks have been building rifles for a long time, just under a different name.<\/p>\n<h2>The Tour<\/h2>\n<p>The R20FFTM is a fixed-stock configuration rifle. Designed for optics, it arrives without iron sights, and that\u2019s just fine with me. They\u2019d only end up getting in the way of my scope mount anyway. If you want to configure primary or backup iron sights, the front Mil-std 1913 gas block rail is the same height as the receiver rail segment, so alignment is easy.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_65101\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65101\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65101\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17-400x300.jpg\" alt=\"The fixed buttstock is a Magpul MOE rifle-length. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-17.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65101\" class=\"wp-caption-text\">The fixed buttstock is a Magpul MOE rifle-length unit.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_65102\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65102\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65102\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15-400x300.jpg\" alt=\"There's a rubber pad on the back of the buttstock. if you want to increase length of pull, you can order a thicker one from Magpul. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-15.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65102\" class=\"wp-caption-text\">There&#8217;s a rubber pad on the back of the buttstock. if you want to increase length of pull, you can order a thicker one from Magpul.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>You\u2019ll notice plenty of Magpul furniture on the base rifle \u2013 another welcome configuration decision. The buttstock is a Magpul MOE Fixed model, and it has a lot going on. The entire comb of the stock is wide and smoothly sloped offering generous cheek weld area. There\u2019s a molded-in sling loop on the underside, but there are also four sockets \u2013 two on either side at the receiver and butt end where you can add push-button QD attachment points. The butt pad is rubber and covers a hinged door, so there\u2019s room in the stock to store important things like spare parts or bacon jerky for those long days in the field. All in all, it\u2019s a nice stock, and I like the way it feels.<\/p>\n<p>The front handguard is a Magpul MOE M-Lok rifle-length model. It has six M-lok slots along the bottom and three on each side in the ten and two o\u2019clock positions so that you can mount rail segments or any other M-Lock compatible accessories. The handguard mounts using the standard delta ring, so it\u2019s not a free-floated system. The sides are smooth while the bottom has rounded ridges which help you set and maintain hand placement. There\u2019s also a small ridge on the lower front which helps prevent your hand from sliding forward onto the gas block. Just forward of this ridge is a metal sling swivel so you can attach there or to one of the M-Lok points if you like. Sadly, there\u2019s no bayonet lug, so if you buy this rifle, Senator Dianne Feinstein won\u2019t shed quite as many tears, but that\u2019s OK. I think bayonet charges are mostly a thing of the past anyway.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_65103\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65103\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65103\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9-400x300.jpg\" alt=\"The handguard is also from Magpul and features M-Lock attachment points at the 2, 6, and 10 o'clock positions.\" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-9.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65103\" class=\"wp-caption-text\">The handguard is also from Magpul and features M-Lok attachment points at the 2, 6, and 10 o&#8217;clock positions.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_65104\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65104\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65104\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14-400x300.jpg\" alt=\"If you need to stash emergency gear like bacon jerky, there's a hollow area in the stock. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-14.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65104\" class=\"wp-caption-text\">If you need to stash emergency gear like bacon jerky, there&#8217;s a hollow area in the stock.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>The pistol grip is also upgraded, but it\u2019s a Hogue over molded model. In short, you\u2019re not getting the basic AR-15 plastic furniture components that you\u2019ll want to upgrade right off the bat.<\/p>\n<p>The upper and lower receivers are machined from 7075 T6 aircraft aluminum forgings. Just behind the pistol grip, you\u2019ll find more QD sling attachment points on either side. The trigger guard is machined into the lower receiver so you can\u2019t replace that with an oversized model. The interior space is generous, however, and I didn\u2019t have any trouble using gloves.<\/p>\n<p>The barrel is 20 inches long and made from 4150M Chrome Moly Vanadium 11595E steel. It\u2019s got a 1:10-inch right-hand twist rate and uses six lands and grooves. The rifle comes with an A-2 birdcage style flash hider.

It weighs about a pound and a half, not counting the Leupold one-piece offset mounting system. Yes, you can use this scope as an impact weapon if all else fails, but that\u2019s another story. For the ranges appropriate for .308 Winchester, the 10x fixed optic was a great pairing, and certainly a configuration I might keep on this setup.<\/p>\n<p>The trigger and hammer components are all standard AR-15 parts, so you can swap out with custom components if you like. The factory trigger is all mil-spec. It\u2019s got a very short takeup followed by a crisp break as far as standard AR triggers go. I measured the pull weight from the center of the trigger, and it averaged about 6\u00be pounds.<\/p>\n<p>As we all know, recoil never really disappears, it just gets redirected and hidden depending on the situation. With an AR direct gas impingement design like on the R20FFTM-308, much of the recoil energy is either siphoned off or spread out over time, making the impulse felt by the shooter greatly reduced when compared to a fixed-action rifle of the same caliber. If you shoot a bolt-action .308 next to this one, the Windham feels very tame in comparison. You can shoot this rifle a lot with no discomfort.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_65113\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65113\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65113\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7-400x300.jpg\" alt=\"I've not yet needed it, but the classic bolt forward assist is there. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-7.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65113\" class=\"wp-caption-text\">I&#8217;ve not yet needed it, but the classic bolt forward assist is there.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_65114\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65114\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65114\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13-400x300.jpg\" alt=\"All the controls are right where you would expect, and for the most part, interchangeable with standard AR-15 parts. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-13.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65114\" class=\"wp-caption-text\">All the controls are right where you would expect, and for the most part, interchangeable with standard AR-15 parts.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>I tested a variety of factory and handloaded ammunition in this rifle for function, velocity, and accuracy.

As mentioned earlier, the .308 packs a much bigger punch than the .223 Remington\/5.56mm NATO. While energy and momentum don\u2019t reflect the whole story, you can make a rough assumption that the bigger cartridge offers double the energy and momentum performance. If you\u2019re looking for more oomph for hunting, penetration, and terminal performance, the .308 AR rifle might be for you. The .308 cartridge also offers better performance at distance. While it\u2019s not an ideal \u201clong range\u201d cartridge, it\u2019ll perform just fine at 800 or 1,000 yards with the right ammo. And you can count on this Windham Weaponry rifle to deliver those rounds capably!<\/p>\n<p>For more information, visit\u00a0<a href=\"https:\/\/www.windhamweaponry.com\/pdf\/NewTechSeets\/R20FFTM-308-3-15-16-MSRP.pdf\" campaign=\"Windham308\" target=\"_blank\" class=\"clickTracking\">https:\/\/www.windhamweaponry.com\/pdf\/NewTechSeets\/R20FFTM-308-3-15-16-MSRP.pdf<\/a>.<\/p>\n<p>To purchase a Windham Weaponry .308 AR on GunsAmerica.com, click this link:\u00a0<a href=\"https:\/\/www.gunsamerica.com\/Search.aspx?T=windham%20308\" campaign=\"Windham308\" target=\"_blank\" class=\"clickTracking\">https:\/\/www.gunsamerica.com\/Search.aspx?T=windham%20308<\/a>.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_65115\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65115\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65115\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19-400x300.jpg\" alt=\"I've been shooting several types of match, defensive, and hand loaded ammo through the Windham. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-19.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65115\" class=\"wp-caption-text\">I&#8217;ve been shooting several types of match, defensive, and hand loaded ammo through the Windham.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_65116\" style=\"width: 410px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20.jpg\" target=\"_blank\" class=\"clickTracking\" campaign=\"windham-weaponrys-big-boy-308-ar-full-review\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65116\" title=\"Windham Weaponry's Big Boy .308 AR\u2014Full Review\" class=\"size-medium wp-image-65116\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20-400x300.jpg\" alt=\"I did accuracy testing using a Hawke Optics Sidewinder Tactical 10x scope from 100 yards. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20-768x576.jpg 768w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20-1024x768.jpg 1024w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/10\/Windham-Weaponry-R20FFTM-308-20.jpg 1200w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-65116\" class=\"wp-caption-text\">I did accuracy testing using a Hawke Optics Sidewinder Tactical 10x scope from 100 yards.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The R20FFTM from Windham Weaponry is a top-quality .308 AR at a very reasonable price.
