SB Tactical SBT5K Pistol Stabilizing Brace – Black
Purpose-built stability for your MP5K and SP5K platform.
The SB Tactical SBT5K™ Pistol Stabilizing Brace enhances your MP5K/SP89-style pistol with a side-folding, low-profile design built into a molded polymer end cap. Designed for 2-pin “K” model receivers, the SBT5K offers a secure fit, improved control, and a QD sling socket for flexible sling options.
This ready-to-install brace features an integral side-folding mechanism, a durable adjustable nylon strap, and rugged polymer construction. Compatible with popular 9mm roller-delayed blowback platforms like the HK SP5K, PTR 9KT, Century Arms AP5-P/AP5-M, and most SP5K clones—as long as your pistol uses 2 rear push pins.
