Kaw Valley Precision Thread Adapter 13.5x1 LH to 5/8x24

The Kaw Valley Precision Thread Adapter converts 13.5x1 LH (metric left-hand) barrel threads to the standard American 5/8x24 thread pattern. It lets shooters mount the wide range of 5/8x24 muzzle devices, linear compensators, flash hiders, and other thread-on accessories on firearms that ship with metric left-hand factory threading.

Install the adapter onto the existing 13.5x1 LH barrel in the left-hand direction, then thread on any standard 5/8x24 muzzle device. It is a clean, straightforward solution for pistol-caliber carbines, PCC platforms, and other host firearms that use non-standard European threading. Part number KVPADPT1314.
