SB Tactical SBT5K Pistol Stabilizing Brace MP5K/SP89 Black

The SB Tactical SBT5K is a purpose-built pistol stabilizing brace engineered for the HK MP5K family of subguns and pistol-pattern clones. It features an integral side-folding mechanism paired with a molded polymer end cap, providing an ergonomic shoulder surface while keeping the host firearm compact, balanced, and maneuverable.

The SBT5K is built to fit 2-pin "K" pattern lowers, including the HK SP89, HK SP5K, PTR 9KT, and Century Arms AP5-P, along with other MP5K-pattern clones. Note: this model is NOT compatible with the standard HK MP5 or the MP5K Reverse Stretch.

The unit ships as a complete, ready-to-install assembly and includes an adjustable nylon strap for one-handed stabilization. Finished in black polymer with an overall length of 10.2 inches and a weight of 12.4 oz, the SBT5K brings SB Tactical's signature combination of clean polymer engineering and reliable folding hardware to the MP5K platform.
