The Griffin Armament Griffin Universal Piston for Sig Sauer SRD CAM-LOK is a patented universal QD piston attachment system designed to deliver rapid, secure mounting on Browning-style action pistols while eliminating common issues associated with traditional direct-thread pistons. The bronze-colored piston installs within the suppressor and pairs with CAM-LOK barrel adapters to provide a three-position, 120-degree mounting interface that accepts tools for precise torque, delivering a taper-lock engagement that remains secure even as the piston reciprocates during firing. By replacing the single-piece direct-thread design, the CAM-LOK system minimizes baffle and end-cap strikes and reduces the need for constant retightening, which translates to fewer range-day disruptions and less service downtime. Engineered for durability, the piston body is fabricated from 17-4 stainless steel and heat-treated to H900 for improved wear resistance, while maintaining identical total system weight to legacy pistons. The universal design ensures compatibility with CAM-LOK barrel adapters and other pistons within the CAM-LOK family, enabling seamless cross-compatibility across various host firearms and suppressor configurations without disassembly.
