SB Tactical FS1913A Pistol Stabilizing Brace | Aluminum

SB Tactical FS1913A Pistol Stabilizing Brace | Aluminum

The SB Tactical FS1913A is the aluminum-strut version of SB Tactical’s FS1913 folding pistol stabilizing brace, built for firearms that use an M1913 (Picatinny) interface at the rear of the receiver. This low-profile, left side-folding brace is a complete, ready-to-install assembly designed around compact host platforms where a traditional receiver extension is not part of the configuration.

The FS1913A uses a 6061 aluminum strut, distinguishing it from the standard FS1913 polymer-strut model. For buyers comparing the two FS1913 variants, the aluminum FS1913A adds rigidity and a more substantial feel while remaining compact at 9.25 inches long and 13 ounces. Its narrow 1.2-inch maximum width helps preserve the slim handling profile expected from a rear-Picatinny folding brace setup.

SB Tactical’s advanced steel hinge design locks in both the folded and extended positions, giving the brace a secure mechanical interface during normal handling. The pull-through opening design supports quick deployment from the folded position, while the left-side folding layout helps reduce overall storage length on compatible firearms. The result is a clean, minimal brace assembly that fits naturally on M1913-equipped platforms without adding unnecessary bulk.

Compatibility is centered on firearms with an M1913 Picatinny rail section at the rear of the receiver. SB Tactical lists examples including SIG MPX, SIG MCX, SIG Rattler, Rock River LAR-PDS, and similar rear-Picatinny host platforms. As with any brace or firearm accessory, confirm fitment with your specific receiver interface and applicable requirements before installation.

The FS1913A includes an adjustable nylon strap with a 1-inch strap width for user fit adjustment. The complete assembly format simplifies setup for compatible firearms, while the aluminum strut, folding hinge, and compact dimensions make this model especially relevant for builders who want the FS1913 profile with the added structure of the aluminum variant.
