Kaw Valley Precision 3 Lug Barrel Adapter 5/8x24

The Kaw Valley Precision 3-Lug Barrel Adapter converts any 5/8x24-threaded barrel into an HK-pattern tri-lug interface, allowing direct attachment of popular three-lug suppressors with no tools or shims required.

Machined from 4140 steel on a high-tolerance Swiss lathe, this adapter delivers exceptional ID/OD concentricity for a snug, repeatable lock-up with your can. The KVP 3-Lug is built to 9mm specifications; Kaw Valley Precision specifically notes the 5/8x24 version is not recommended for .45 ACP or other large-bore cartridges also threaded in 5/8x24.

Measuring 2.33" long with a black finish, the KVP 3-Lug is a clean, minimal solution for pistol-caliber carbine builds, PCCs, and anyone running a tri-lug suppressor.
