Kaw Valley Precision 3-Lug Barrel Adapter 1/2x28 4140 Steel

The Kaw Valley Precision 3-Lug Barrel Adapter replicates the popular HK-pattern 3-lug interface, letting you mount a compatible tri-lug suppressor or 3-lug accessory directly to a host barrel fitted with a 1/2x28 thread pitch.

Precision Swiss-lathe machined from 4140 steel, this adapter provides a secure, repeatable 3-lug mounting surface. The 1/2x28 male thread installs to the host barrel and presents the standard 3-lug pattern at the muzzle for fast attachment and removal of tri-lug silencers.

Approximate dimensions are 0.85" x 2.50" x 2.75", making this a compact drop-on solution for 1/2x28 threaded barrels.
