SB Tactical Side Folding Brace - Black Polymer Housing

The SB Tactical side folding brace is a complete, ready-to-install stabilizing assembly designed for shooters running HK MP5, MP5K, and compatible 9mm platforms. Built with a molded polymer housing and integral side-fold mechanism, this brace collapses when not in use—ideal for shooters who need a compact platform for tactical drills, home defense, or range work without sacrificing stability during firing. SB Tactical engineered this brace in the USA, and it ships as a full assembly with hardware and adjustable nylon strap, so you can install it and get to work.

The polymer construction keeps weight down at 13.5 ounces, while the integrated QD socket adds utility for sling attachment. The side-folding design folds away cleanly without eating up real estate in a safe or bag, and the brace deploys quickly when you need it. Whether you're tuning a PTR 9CT, Zenith ZF-5, Century Arms AP5, or another MP5 clone platform, this brace adapts to your setup. The 1-inch strap keeps your forearm secure without bulk.

Before ordering, verify your pistol has a single push pin—this brace will not fit dual push-pin configurations. While most modern MP5 clones use the single-pin design, fitment tolerances between manufacturers can vary slightly, and a gunsmith may need to do minor fitting work. As with all stabilizing braces, SB Tactical designs these for forearm support only, not shoulder firing; always confirm your local and federal regulations before assembling or configuring your firearm.

Frequently Asked Questions

Will this fit my MP5 clone?

Yes, this brace fits HK MP5, MP5K, SP5, Century Arms AP5, Zenith ZF-5, PTR 9CT, and most MP5 clones chambered in 9mm—but only if your pistol has a single push pin. If your firearm has two push pins, this brace will not fit. Check your gun against the product images before ordering.

What comes in the box?

The SB Tactical side folding brace ships as a complete assembly with all necessary hardware and an adjustable nylon strap. It is ready to install, though gunsmith fitting may be required due to manufacturing tolerances between different MP5 clone makers.

Can I fold it away for storage?

Yes. The integral side-folding mechanism allows the brace to collapse when stowed, making it more compact in a safe, range bag, or vehicle without sacrificing stability when deployed and in use.

Is there a QD socket for a sling?

Yes. The molded polymer housing includes a QD socket for easy sling attachment and adjustment.
