Upper Group, DISSENT, Mk4, 300 BLK, 14.5" P&W
Start your new bufferless build or add to the options for your existing DISSENT® lower with the 14.5" 300BLK upper group. Although the barrel is only 14.5" long, this upper comes with the ZEROED SVD brake pinned and welded to the end, bringing the total length to 16.1", allowing the use of stocks and braces without having to SBR anything.
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 ARs. The forward non-reciprocating side charger allows for quick bolt operation without coming off target. Direct impingement DISSENTS come equipped with a left side charger standard. Right side charging handles for DI models are available here.
All DISSENT Upper groups include a lower receiver end plate and choice of adapter including: 1913 Picatinny rail, buffer tube adapter, or DISSENT folding stock. DISSENT Upper groups are available in your choice from seven Cerakote finish options or hard coat anodized.
Adjustable Gas Block
If you’re looking to shoot suppressed or just fine tune your DISSENT to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking. Never too much and never too little.
