SB Tactical SBT5K Folding Brace SP5K

The SB TACTICAL SB-T5K Folding Pistol Brace BLK (SKU: SBT5K-01-SB) is the industry-leading stabilization solution for the MP5K platform. Designed specifically for the “K” (short) receiver, this brace pays homage to the iconic side-folding stocks of the 1980s while providing the modern functionality required for a large-format pistol.

Whether you are running a genuine Heckler & Koch MP5K, SP5K-PDW, a Century Arms AP5-P, or a PTR 9KT, the SBT5K transforms your firearm into a more controllable, stable, and accurate platform without the legal hurdles of a Short Barreled Rifle (SBR) tax stamp.

Iconic Design Meets Modern Utility

The SBT5K was developed in conjunction with the experts at Heckler & Koch to ensure the aesthetics remained true to the platform’s heritage. The side-folding mechanism allows you to minimize the footprint of your PDW for storage in backpacks or discreet cases. When deployed, the high-quality synthetic rubber provides a comfortable cheek weld and a solid point of contact, significantly reducing felt recoil and muzzle flip.

Why the SBT5K is a “Must-Have” Upgrade:

• Side-Folding Versatility: The brace folds securely to the right side, allowing the firearm to be fired and operated even when the brace is stowed.

• Enhanced Stability: By adding a third point of contact, the SBT5K drastically improves accuracy during rapid strings of fire.

• NFA-Free Solution: Designed as a stabilizing brace, it allows you to maintain your firearm’s pistol status under current federal guidelines (always check your local and state laws).

• OEM Aesthetics: The sleek, black finish and textured rubber perfectly match the factory finish of the MP5K family.

Key Features and Benefits

• Complete Assembly: Includes the side-folding mechanism, the stabilizing brace, and a reinforced adjustable nylon strap for a custom fit.

• Tool-Free Deployment: The friction-lock folding mechanism is robust and intuitive, allowing for rapid transition from a folded to a deployed state.

• Lightweight Polymer Construction: Engineered from high-strength, impact-resistant polymer to handle the vibration of the roller-delayed system without adding unnecessary bulk.

• Made in the USA: Proudly manufactured in the United States, counting toward 922R compliance where applicable.
