SB Tactical SBA4 pistol brace on an AR-15


If you’re 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 an accessory like the SB Tactical SBA4 brace, you can get around this issue. You’ll also benefit from buying an SBA4 pistol brace by using it to stabilize an AR pistol and take better control of it.


Those in the market for an SBA4 brace will find that the SB Tactical SBA4 Pistol Stabilizing Brace is an excellent option. It’s made from high-strength polymer and will work with any Mil-Spec carbine buffer tube.

This SBA4 pistol brace has a 5-point adjustable length of pull and an adjustable nylon strap that will enable you to attach it to your arm to provide added stability. With its minimalist drop-in design, it’s also very easy to install, and it features an integral ambidextrous QD sling socket that can be utilized with a sling attachment.

On top of all that, the SBA4 brace is designed and made in the U.S. by a veteran-founded company, so purchasing firearm parts like this will prove to be a great way to support our veterans.
