The Griffin Armament CAM-LOK Barrel Adapter in .578x28 is a quick-detach piston interface designed to modernize suppressor mounting on browning-style blowback pistols. Unlike older direct-thread designs, this patented QD system delivers faster attachment and removal with a more secure lock-up—critical for shooters who run multiple hosts or need reliable suppressor repeatability between sessions. The CAM-LOK uses a forward taper that mates with the piston to minimize baffle strikes and reduce end-cap wear, a real advantage if you're shooting suppressed regularly and want to extend component life.

Built around a coarse-thread design with top-cut threads, the adapter resists wear better than standard cuts and accommodates a 3/4-inch (19mm) wrench for tool-assisted installation and removal. The system offers three mounting positions, spaced 120 degrees apart, so you can find a firing position that works for your grip and sight picture without fumbling. The QPQ nitride finish delivers a clean, durable black appearance while protecting against corrosion.

This is a precision piece: the internal bore is optimized to reduce side concussion and visual disturbance compared to traditional blind-baffle designs. Weight is on par with legacy direct-thread pistons, so you won't see a difference in muzzle rise or felt recoil. Remember that compatible universal QD pistons are sold separately—confirm your suppressor model before ordering to ensure the piston fits your can.
