Griffin Armament
The Griffin Armament Piston Barrel Adapter 16x1 LH is a precision threaded muzzle component engineered for shooters running Griffin's CAM-LOK universal quick-detach suppressor systems. If you're building a dedicated suppressed rifle or maintaining multiple cans across your firearms collection, this adapter threads directly to your barrel and accepts any compatible Universal QD piston—letting you swap suppressors in seconds without breaking down the rifle or losing zero. The 16x1 left-hand thread pitch is a specific fitment, so verify your barrel before ordering.
Built from 17-4 stainless steel and finished in QPQ Nitride for durability and corrosion resistance, the adapter features Griffin's patented CAM-LOK mounting interface: three locking positions separated 120 degrees apart ensure rapid, repeatable mounting regardless of suppressor orientation. The forward taper surface locks solidly against the piston, effectively reducing or eliminating the baffle strikes and end-cap rattle that plague loose-fitting systems. The internal bore profile minimizes side concussion and visual disturbance compared to traditional blind-bore designs—a practical advantage on precision rifles or during low-light shooting. Installation is straightforward: the 3/4-inch (19mm) wrench pattern accepts standard sockets for secure hand-tight installation without over-torquing.
The adapter weighs the same as Griffin's legacy direct-thread pistons, so you're not adding bulk to your rifle system. It's compatible with Universal QD pistons (sold separately) and also supports the Universal Carry Comp, making it a flexible choice whether you're silencing a hunting rifle, running a do-everything AR, or testing different suppressor configurations on the same host firearm. Coarse threads are top-cut for enhanced durability under repeated mounting and dismounting cycles.

The Griffin Piston Barrel Adapter is threaded 16x1 left-hand. You must verify your barrel's thread pitch and hand before purchasing—this is not a universal fit. If your barrel is not 16x1 LH, this adapter will not thread on correctly.
This adapter works with Griffin Armament Universal QD pistons (sold separately) and the Universal Carry Comp. It uses the patented CAM-LOK quick-detach interface, so you'll need a compatible piston to attach a suppressor.
Yes, you can move this adapter from one rifle to another, as long as both have 16x1 left-hand threaded barrels. The CAM-LOK system lets you swap suppressors between different hosts without removing the adapter.
The listing covers the adapter itself. Universal QD pistons and suppressors are sold separately.
