New factory HK Mark 23 SOCOM thread protector

This is the only thread protector that HK offers that will fit the HK Mark 23 Pistol. This is a hard-to-find item and a must-have for all MK23 Owners.

Compatible with:

• All H&K Mark 23/ SOCOM barrels threaded 16mm x 1 right hand twist

Please note: That this will fit the Mark 23 pistol and NOT the USP 45 and HK45 pistols. They use a different thread protector found in the other HK 45 pistol parts sections.
