Kaw Valley Precision Thread Adapter 1/2x28 to 5/8x24 Black

The Kaw Valley Precision Thread Adapter is a precision-machined barrel thread converter that lets you mount a 5/8x24 threaded muzzle device or suppressor on a barrel threaded in the standard 1/2x28 pattern. Intended for use on 9mm and under-caliber host firearms and confirmed compatible with .45 ACP applications, this adapter bridges the gap between your barrel thread pitch and your chosen muzzle accessory without any permanent modification to the barrel.

Each adapter is Swiss lathe produced from quality steel with a durable black finish, delivering the tight ID/OD concentricity that KVP is known for. The adapter measures 1.35" long with an OD of 0.84" and an OD thread length of 0.60", providing a secure, aligned fit between barrel and muzzle device.

Whether you are adapting a pistol-caliber carbine barrel to a 5/8x24 compensator or running a 9mm build with a suppressor that uses the larger thread pitch, the KVP Thread Adapter offers a simple and economical solution that keeps your point of impact consistent.
