$1,576.90
Pack some 30 Cal power into a pint size PDW. Perfect for your existing Mk4 DISSENT lower or standard AR15 lower group, this upper group combines utility, innovation, and unmatched style that lets you build or swap your DISSENT to 300BLK. Take your pick from six unique Cerakote finishes, curated for even the most discerning tastes. Its no secret that pistol stabilizing braces have been a target for scrutiny over the years, and those that enjoy building their own AR pistols have wondered what will come out of all the uncertainty. DISSENT is our answer. Utilizing our patent pending direct impingement Compact Action, DISSENT upper groups house the entire action and recoil assembly in the upper receiver resulting in less bulk and length than traditional AR pistols. The forward non-reciprocating side charger allows for quick bolt operation without coming off target. DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube. Adjustable Gas Block 300 BLK is an incredibly adaptable cartridge with different loadings for specific uses, like suppressed. With the adjustable gas block on each 300 BLK DISSENT you can fine tune the gas system to best suit the supersonic or subsonic ammo loadings you like best. Backed by Lifetime Quality Guarantee against material and workmanship defects.

If you want a buffer-less pdw length upper under 9 inches compatible with a Milspec ar lower there aren’t a lot of options out there. The only other option with a 6 inch barrel I can think of is the sig rattler upper but those cost about $600 more than this one. Great fit and finish and functions well. If you’re looking to build a super compact pdw the cmmg dissent upper is a solid option. Would recommend.
