SMC Bravo Chassis (Ruger RXM)

The Strike Industries SMC Bravo for Ruger RXM takes the RXM serialized fire control unit out of the factory Magpul grip frame and seats it in a 1913 Picatinny brace-ready module. Strike Industries applied the same modular chassis concept to the SIG P320, and the RXM version brings it to a Glock-pattern host.

The chassis is polymer, 6 ounces, and measures 9.58 inches long with a compact grip profile. The defining feature is the integrated 1913 Picatinny rail at the rear of the frame, which accepts 1913-interface braces such as the SB Tactical FS1913, A3 Tactical HDA3, and Strike Industries folding adapters, or a 1913-interface rifle stock where legally configured. A double-undercut trigger guard improves the high grip position for recoil management, and an integrated accessory mounting point allows for future Strike Industries add-ons. The compact grip module profile keeps the platform short enough to remain compatible with PDW carriage solutions.

Legal note: mounting a 1913 brace on a pistol-configured RXM produces a braced pistol (the 2023 ATF brace rule was vacated by the 5th Circuit and is not being enforced). Mounting an actual rifle stock requires an ATF Form 1 SBR registration first; the One Big Beautiful Bill Act zeroed the federal making tax to $0 in 2026, but the eForm 1 registration process still applies and now runs days, not months. Check state law before mounting any stock or brace.
