Looking to pack the long-range performance of .243 or .308Win without the weight of a larger AR-10/LR-308 rifle? It might be time to take a look at 6mm ARC. With flat shooting characteristics and compatibility with AR15 (or Mk4 DISSENT) platforms, this 6mm ARC DISSENT may just be the ultimate long-range carbine. Hosting an array of ZEROED parts and accessories, the DISSENT builds on the renowned AR15 manual of arms. 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. 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.
