All components are made of mil-spec materials and are manufactured under strict, ISO quality control standards. The heat-treated, welded aluminum body is hard-anodized for superior corrosion resistance, then given a tough, dry-lube coating to eliminate the need for additional lubricants that would attract dust, sand, or dirt. The latest military-type, glass-fiber reinforced composite follower further guarantees flawless feeding in the harshest tactical conditions. With the new, high lubricity, dry-lube-coated chrome silicon spring that’s corrosion-resistant certified to 500 hour salt spray standards, and less prone to spring “set.”
