CMMG Large Frame Dissent Mk3 in .308, 6.5 Creedmoor, and 8.6BLK

CMMG is expanding its Dissent lineup of rifles, pistols, and pistol-caliber carbines with the new Dissent Mk3 large frame platform in .308, 6.5 Creedmoor, and 8.6BLK. Sharing a familiar manual of arms with previous models, the direct impingement Dissent Mk3 incorporates CMMG ZEROED controls and trigger, free float M-LOK handguard, and a reversible non-reciprocating forward charging handle in addition to its upsized Compact Action.


Configurations


The CMMG Mk3 Dissent comes with a wide variety of shooters in mind, from those who appreciate a subsonic big-bore PDW to the Designated Marksman. Once you choose a caliber, barrel length, color, and stock or stabilizer brace option, the possibilities seem numerous. Here is a quick breakdown.


The CMMG Dissent Mk3 is available in rifle, pistol, and SBR configurations, with barrel lengths of 12.5”, 16”, and 20”. The most common caliber is .308, which appears in all available barrel lengths. The next most common caliber is the 8.6BLK, which is available in both 12.5” and 16” variants. Finally, the 6.5 Creedmoor is available in the 20” rifle configuration only.


All Dissent Mk3 models include a picatinny rail at the rear of the receiver. 12.5” pistol models are available with the bare rail or an SB Tactical folding stabilizer brace. 16” models also come with the option of a bare rail or folding stock. The 20” rifles come from the factory equipped with folding stocks.


Pick A Color


All of these configurations come in the following seven Cerakote options:

  • Armor Black
  • Charcoal Green
  • Coyote Tan
  • Midnight Bronze
  • Sniper Grey
  • Titanium
  • Tungsten


Magazines


The CMMG Dissent Mk3 is based on the DPMS LR308 Gen 1 High Pattern design and accepts LR-308/SR25 pattern magazines. Speaking of magazines, each Dissent Mk3 comes from the factory with two supplied magazines, while compliance states receive 10 rounders in lieu of standard capacity. 


Folding it up


Rifles and carbines with folding options and no need for a buffer tube are all the rage these days, however, most of them that can be fired while folded tend to be short-stroke gas-piston operated rather than the traditional simplicity of direct impingement gas operation. I like the idea of the forward non-reciprocating charging handle as that means fewer openings near my face for a lighter diet of gas, especially running suppressed.


The CMMG Mk3 is available now with an MSRP of $2,049.95 - $2,299.95. Let us know in the comments below what you think of the Mk3, and I’d love to hear your opinions on DI vs piston-driven gas systems. Do you prefer a folding stock option that isn’t beholden to a traditional buffer tube? Lastly, are you one of those guys interested in a big-bore PDW? Asking for a friend…

    2k+ for a direct impingement rifle is insane to put it lightly.

      True but honestly with a SCAR being nearly $4K and the fact that FN will void your warranty if shooting suppressed Id rather take the CMMG if it runs good

    Every time I see a new “AR10” variant come online, I just have to stifle a yawn. Big, heavy, unwieldy. POF Revolution DI has every one of these things beat by a country mile. Under 7 pounds. MOA accurate, great trigger, exact same ergonomics as a AR15. Literally the softest recoiling AR anything I’ve ever shot that isn’t a 5.56. Yeah it’s expensive. Buy once and cry once I guess.
