Many of you love the 6.5 300BLK DISSENT, so we decided to take it and crank it up to 11!… or how about 10.5? Giving you improved ballistics and an even more suppressor friendly length, this all new length 300BLK upper is just the ticket to finish your 300BLK AR pistol build. 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.

I am building my own bufferless 300-blk AR, and I ended up picking this over the BRN. One advantage with CMMG is that they include a buffer adapter that goes right where your traditional stock would go. Many companies try to sell you an adapter well into the $200s while it is included with CMMG. I have not shot it yet, but the fit and finish looks great and it cycles fine from the dry firing.
