Angstadt Arms 3‑Lug Flash Hider

The Angstadt Arms 3‑Lug Flash Hider is designed to provide compatibility between threaded barrels and suppressors that use a standard 3‑lug mounting system. The adapter installs directly onto barrels threaded 1/2×28 and features a universal 3‑lug interface commonly used on pistol‑caliber suppressors. Constructed from hardened steel with a black nitride finish, it is intended for durability and corrosion resistance. The adapter does not require shims for installation, though shims may be used if timing adjustments are needed. A crush washer is not recommended. Available in either 1/2x28 or 1/2x36.
