Griffin Armament Piston Barrel Adapter .578x28 CAM-LOK Universal QD Mount

The Griffin Armament GRIFFIN PISTON BBL ADAPTER .578X28 CAM-LOK offers a patented Universal QD piston attachment system with three mounting positions set 120 degrees apart for rapid, repeatable mounting and streamlined setup. This adapters forward taper surface locks in place with interfacing piston and dramatically reduces or eliminates common baffle and end cap strikes, while its coarse threads are top cut to boost durability and wear resistance for long-term reliability. Designed for secure and easy installation, the 3/4 or 19mm wrench pattern accommodates a socket wrench, enabling fast on-site adjustments without sacrificing torque. Compatible with Universal QD pistons (sold separately), the internal bore minimizes side concussion and visual disturbance compared with blind muzzles, preserving sight picture and reducing muzzle blast clutter during precision or quiet operation. With a total system weight identical to legacy direct thread pistons, this adapter pairs precision machining with a durable QPQ nitride finish on 17-4 stainless steel to deliver attractive, long-lasting performance. It also supports Universal Carry Comp and other suppressor mounting devices, making it a versatile addition for suppressor parts and mounting applications where quick, secure piston-based attachments are required.
