KVP adapters convert BARREL thread pitches “to” desired MUZZLE device thread pitches. For example, 1/2×28 (barrel thread) to 1/2×36 (muzzle device/suppressor thread), converts a barrel threaded 1/2×28 to 1/2×36 for installation of corresponding muzzle devices or suppressors. Not Intended for applications larger than 9mm diameter projectiles. NOTE: ADPT-1311 (.578×28 to 5/8×24) can be used in .45 ACP applications!
