Griffin Armament 3-Lug Adapter 1/2x28 – Quick-Attach Suppressor Mount

The Griffin Armament 3-Lug Adapter converts standard 1/2x28 threaded barrels to accept 3-lug quick-detach suppressors, eliminating the need to thread and unthread cans. This adapter installs permanently on your barrel and allows rapid suppressor attachment and removal with a simple push-and-twist motion, making it ideal for shooters who frequently switch between suppressed and unsuppressed configurations or move suppressors between multiple host firearms.

CNC-machined from heat-treated steel with a black nitride finish for corrosion resistance and durability. The adapter installs directly onto 1/2x28 threaded muzzles and requires proper torque and timing. Compatible with Griffin Armament 3-lug mount suppressors and other industry-standard 3-lug systems. Ensure adequate barrel clearance behind the adapter for full suppressor seating. This is a muzzle device only—suppressor and appropriate NFA paperwork sold separately.
