Product Overview

HBI Short Stroke Buffer for your Grand Power Stribog SP9A1 and SP9A3.The increased length of the HBI buffer reduces reward bolt travel and prevents spent cases from becoming lodged in the receiver. The buffer is molded from high performance polyurethane and is slightly softer than the factory buffer pad. Its advanced geometry has been proven to dampen and distribute bolt energy, significantly reducing felt recoil. 

The Short Stroke Buffer is compatible with all “Gen 2” Stribog models, including SP9A1 (direct blowback) and SP9A3 (delayed blowback) variants. If your Stribog is a “Gen 1” model, or if your bolt has TWO recoil rods between the bolt and buffer, the Short Stroke Buffer will NOT fit.

Please Note: The Short Stroke Buffer is designed for semi-auto only. We do not recommend it for use with Binary Trigger or Select Fire variants of the Stribog.
