Available Now

Available at CMMG dealers and online at CMMG.com starting July 30th, 2024. The DISSENT Mk3 brings bufferless versatility to 308 Winchester, 6.5 Creedmoor, and the new hotness on the block, 8.6 Blackout.

The bigger beefier brother to the Mk4 DISSENT line, the Mk3 utilizes the same familiar manual of arms with the ZEROED controls, reversible non-reciprocating forward charging handle, and an upsized direct impingement Compact Action. Available at launch with three caliber options, configurations include rifles, pistols, and SBRs. Whether you're searching for a big bore PDW (personal defense weapon) to run subsonic ammo or a long range DMR (designated marksman rifle) for days in the field, there is a DISSENT Mk3 for almost every need.

Calibers

A large frame DISSENT of course means that you can have your bufferless AR10 cake and eat it too. The iconic .308 Win and 6.5 Creedmoor of course make themselves at home in the Mk3 DISSENT, joining the faithful pair of calibers is the much anticipated 8.6 BLK.

8.6 BLK

Building off the 300BLK's playbook, 8.6 BLK utilizes the same existing AR10/SR25 pattern magazines that the .308 Win and 6.5 Creedmoor use and utilizes the same BCG. The cartridge itself even uses 6.5 Creedmoor as the parent case necked up to an 8.6mm (.338 caliber) projectile.

8.6 BLK makes the most of shorter barrels thanks to its incredibly fast 1:3 twist rate and imparts significantly more energy on target compared to its older brother 300 BLK, making this an incredible hunting and self defense round.

Barrel Lengths

The DISSENT Mk3 is available in three barrel lengths: 12.5", 16.1", and 20", with multiple configurations depending on caliber. 20" DISSENT Mk3s are available as rifles, 16.1" available as rifles or pistols, and 12.5" available as SBRs or pistols (with or without FS1913A folding brace).

Enhanced Trigger

Triggers can make or break a gun, so of course we put the superb ZEROED Single Stage Drop-In Trigger into all Mk3 DISSENTS. Made to ignite even the toughest steel case primers, the ZEROED trigger is compatible with a variety of AR platforms including AR15, AR10/LR-308, Mk47®, and DISSENT® firearms. With a 4.5lb pull weight and single-stage operation, the ZEROED trigger is a great choice for compact personal defense weapons and long-range precision rifles alike.

Multiple Cerakote Colors

Available in seven Cerakote options, there's a Mk47 to suit any taste.

Bufferless Compact Action

The direct impingement AR10 size BCG has evolved into Compact Action form, ditching the need for a traditional buffer tube and action spring system.
