SB Tactical Folding PISTOL STABILIZING BRACE / M1913 PICATINNY FS1913A™ 6061 Aluminum Strut

SB Tactical Folding Pistol Stabilizing Brace Overview

The SB Tactical FS1913A brace gives builders a low-profile folding option for platforms that use an M1913 Picatinny interface at the rear of the receiver. This complete assembly uses a left side-folding design and a lightweight 6061 aluminum strut, so it offers a clean, durable setup for compatible builds.

SB Tactical designed the FS1913A for quick deployment and solid lock-up when extended. In addition, the advanced steel hinge locks in both the folded and extended positions, while the pull-through design keeps operation simple and consistent. For buyers who want a compact folding Picatinny brace with an aluminum strut, this model offers that upgrade in one complete assembly. You can also browse the FS1913A brace adapter bundle if you need a 22 Charger-ready package.
