Upper Group, RESOLUTE, Mk4, 300 BLK, 14.5" P&W
Short enough to be nimble but long enough to be a rifle-length upper still thanks to the pinned and welded ZEROED SVD muzzle brake bringing the overall barrel length to 16.1". 300BLK has the benefit of using a huge array of standard 5.56 AR15 parts guaranteeing maximum modularity with the performance accompanying the larger 30 cal rounds.
Adjustable Gas Block
Adjustable Gas Block
If you’re looking to shoot suppressed or just fine tune your RESOLUTE 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.
