Precision CNC-machined from heavy brass and treated with a friction-reducing Nitroflon coating, the 6.03mm tight-bore profile delivers enhanced air seal, tight shot grouping, and a noticeable increase in muzzle velocity (FPS). Complete with a high-performance 60-degree GBB hop-up bucking, it maximizes backspin consistency and long-range accuracy for extended carbine builds or suppressed AAP-01 setups
