HB Industries
Low-profile billet 6061 aluminum 1913 Picatinny adapter that mounts any 1913 stock or brace directly to the Stribog upper receiver. Includes integrated QD socket.
The HB Industries 1913 Stock/Brace Adapter is the universal mounting interface for the Grand Power Stribog. Most aftermarket braces and PDW stocks use a 1913 Picatinny back-plate connection; the factory Stribog does not. This adapter bolts to the rear of the upper receiver and presents a 1913 rear surface that accepts any standard PDW brace, folding adapter, or rifle stock that mounts on Picatinny.
The adapter is machined from billet 6061-T6 aluminum and hardcoat anodized to MIL-A-8625 Type 3 spec. An integrated QD socket is built into the adapter body, so a single-point sling can attach without an additional QD swivel installed elsewhere. The low-profile design keeps the stack-up height down, which matters for cheek weld when paired with PDW braces and short stocks.
Fitment covers all Stribog variants: SP9A1, SP9A2, SP9A3, the K-pattern compact models, and 10mm/45 ACP versions. Drop-in install with the Stribog's existing rear hardware; no additional parts or modifications required. Pair with a Strike Industries FSA, KAK Shockwave, SBA3/SBA4, or any 1913 PDW brace. Made in USA.
