Barrel Extensions

The HTI barrel extension is the interface between the monolithic receiver and the match-grade Lother Walther barrel. Because the barrel is indexed on the feed ramp of the extension, it is a critical piece to the repeatable, high-level of accuracy achieved in the Desert Tech HTI platform. This is just for the extension itself. A Desert Tech HTI Barrel Extension is required for any barrel to fit the Desert Tech HTI platform, along with a correctly contoured barrel.
