Description
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 1/2×28 thread pitch.
Precision Swiss-lathe machined from 4140 steel, this adapter provides a secure, repeatable 3-lug mounting surface. The 1/2×28 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 1/2×28 threaded barrels.
