GRIFFIN PISTON BARREL ADAPTER 16x1RH - Precision Threaded Firearm Accessory

The Griffin Armament piston barrel adapter with 16x1 right-hand threading is a precision-engineered component designed for shooters who run Griffin's CAM-LOK quick-detach suppressor system. This threaded adapter serves as the foundation of a modular suppressor setup, allowing you to swap between different cans and configurations without losing zero or dealing with permanent installations. Built from 17-4 stainless steel and finished in QPQ Nitride, it's made to handle repeated mounting cycles and the rigors of both hunting and range use.

The CAM-LOK mounting system uses a patented design with three positioning points separated by 120 degrees, so you can orient your suppressor or muzzle device in the exact position you need. The forward taper surface locks firmly in place with Griffin's Universal QD pistons, virtually eliminating baffle strikes and end-cap rattle—common problems with looser quick-attach systems. A 3/4-inch wrench pattern on the adapter makes installation and removal straightforward with standard tools, and the internal bore geometry reduces side concussion and mirage compared to fully blind designs.

This adapter maintains the same weight profile as legacy direct-thread pistons, so swapping to the QD system doesn't add bulk or shift your balance. The coarse-cut threads are engineered for durability and wear resistance, crucial for an accessory that'll see repeated use. Compatible with Griffin's Universal QD pistons (sold separately) and also supports the Universal Carry Comp, this adapter is the bridge between your barrel and your suppressor or brake—and it does the job with no compromise.

Specifications

Frequently Asked Questions

What suppressors and muzzle devices work with this adapter?

This adapter is compatible with Griffin Armament's Universal QD pistons and the Universal Carry Comp. You'll need a piston designed for the CAM-LOK system to attach a suppressor. Check the suppressor's specifications to confirm CAM-LOK compatibility.

What does the 16x1 right-hand threading mean?

The 16x1 RH specification describes the barrel thread pitch this adapter is cut for. Make sure your barrel is threaded to 16x1 right-hand before ordering. Using an adapter with the wrong thread pitch will not fit safely.

Is this a quick-detach system, or do I need tools to remove it?

This adapter itself is permanently installed on your barrel via the threaded connection. However, it serves as the mounting interface for Griffin's CAM-LOK quick-detach suppressors, allowing you to rapidly attach and detach compatible cans without tools. The adapter stays on your barrel; the suppressor attaches and detaches from the adapter.

Are Griffin Universal QD pistons included?

No, the piston is sold separately. You'll need to purchase a Griffin Universal QD piston compatible with the CAM-LOK system to complete the suppressor attachment setup.
