Angstadt Arms 3-Lug Adapter 9mm 1/2x28 – AR-9 / PCC Suppressor Mounting

The Angstadt Arms 3-Lug Adapter converts standard 1/2x28 threaded 9mm barrels to a 3-lug suppressor mount interface. This adapter enables faster suppressor attachment and detachment compared to direct-thread systems, making it a practical upgrade for shooters who regularly use their suppressor across multiple firearms or need quick-detach capability during range sessions.

Machined from steel with a durable black finish, this adapter threads onto any 1/2x28 barrel and provides a secure, repeatable lockup with 3-lug compatible suppressors. Installation is straightforward with proper tools and thread locker. Compatible with AR-9 pistol caliber carbines and other firearms with 1/2x28 threaded 9mm barrels. Note: Requires a suppressor with 3-lug mounting system. Suppressor use subject to NFA regulations.
