Kaw Valley Precision 3 Lug Barrel Adapter

The KVP 3-Lug adapters are manufactured to replicate the popular HK pattern 3-Lug interface. Concentricity of ID and OD surfaces are paramount in any suppressor attachment. Machined from 4140 steel in a high tolerance Swiss Lathe, these adapters have exceptionally tight ID to OD concentricity tolerances. To top it all off, the KVP 3-Lug adapters are Black Nitride QPQ finished to provide excellent wear properties for a long service life.
