You’ll probably recognize the original Auto-Lock Mojave Buckle (left) from Mystery Ranch Packs. In fact, it was MR founder himself who drove the development of the Gen 2 Buckle (right) in order to provide a more low profile alternative. Both versions provide positive retention of the 1″ webbing they accommodate.
Male and female ends from either generation of the buckle are compatible with one another as well as with other National Molding 1″ SR buckles.
