If you are building an AR pistol with a short barrel, you can't legally put a stock on it without paying the proper tax stamp for an SBR. However, with a pistol brace, you can get around that. In addition, a pistol stabilizing brace helps you stabilize an AR pistol, and it is ideal for a PDW AR pistol.

Designed to Work with Mil-Spec Carbine Buffer Tube

If you are looking for a pistol brace, the SB Tactical SBA4 Pistol Stabilizing Brace is an excellent option. Made from high-strength polymer, this brace can work with any Mil-Spec carbine buffer tube.

The brace has a 5-point adjustable length of pull, and an adjustable nylon strap as well, which allows the brace to be attached to your arm for added stability. With its minimalist drop-in design, the SB Tactical SBA4 Pistol Stabilizing Brace is very easy to install, and it also features an Integral ambidextrous QD sling socket for sling attachment.

The brace is designed and made in the U.S.A. by a veteran-founded company, so using it is a great way to support our veterans.
