Description
The Kaw Valley Precision 3 Lug Barrel Adapter replicates the popular HK pattern 3-lug interface, giving pistol-caliber barrels a quick-detach mount for tri-lug suppressor attachment. Machined from 4140 steel on a high-tolerance Swiss lathe, this adapter is held to exceptionally tight ID-to-OD concentricity tolerances so attached suppressors index cleanly and stay aligned shot after shot.
This version carries 1/2×36 threads and measures 1.5″ long, intended for 9mm and under pistol-caliber builds. A Black Nitride QPQ finish coats the steel for corrosion resistance and a low-glare exterior. Whether you run a 9mm AR pistol, an MP5-pattern platform, or any barrel threaded in 1/2×36, the KVP 3-lug adapter provides a secure, repeatable suppressor interface that swaps quickly in the field without tools.
