New factory HK Mark 23 SOCOM thread protector fits all H&K Mark 23 / SOCOM barrels threaded 16mm X 1 right hand twist. 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.
- 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.
