Designed with the goal of utilizing as many existing AR15 components, 300BLK gives shooters a variety of .30 Cal power to suit their taste. From subsonic to supersonic loadings with a long list of bullet types to match, the 16.1" barrel on this DISSENT® upper group extracts every bit of performance without compromise. Perfect for swapping calibers on your existing DISSENT lower or starting a new build that ditches the AR buffer tube.
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. Direct impingement DISSENTS come equipped with a left side charger standard.
All DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube.
