Bring new life to a firearm that may not sport a common muzzle thread.

KVP thread adapters are the best choice for converting your current barrel thread to a standard thread. Allow yourself the flexibility to attach your favorite muzzle device/suppressor, to multiple weapon platforms!

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!
