Rifle, DISSENT, Mk4, 300BLK, 14.5" P&W
Equipped with a 14.5" barrel pinned and welded to 16.1", this 300 BLK DISSENT® gives you the shortest overall length possible without having to go the SBR route. With all of the supersonic and subsonic cartridge options out there for 300 BLK, there's almost no use case the round won't find itself right at home in; from self-defense or hunting, to target shooting and more.
Available in a variety of custom Cerakote finish options; the rear of every DISSENT rifle features the DISSENT side folding stock with adjustable length of pull and adjustable cheek riser. A forward non-reciprocating charging handle allows for quick and easy manipulation without coming off target and the M-LOK handguard with top picatinny rail provides ample mounting space for whatever accessories you please.
