Overview
The HB Industries 1913 Stock Adapter is the cheapest entry point to the Kuna stock aftermarket. It replaces the factory polymer rear mount and presents a standard 1913 Picatinny rear interface, so any 1913-mounting stock or brace drops straight on. The adapter is 6061-T6 aluminum with a MIL-A-8625 Type 3 hardcoat anodize and includes an integrated QD sling socket. Weight is 3 oz.
Installation is drop-in with no additional parts or hardware. HBI does note the rear takedown pin can fit tightly because aluminum has less flex than the original polymer, so a rubber mallet or punch may be needed on tighter receivers.
