Sig Sauer Off-Duty MPX K SBR 9mm 8" PDW 35RD WRMPX-8B-9-SBR-35

The SIG Sauer MPX K Off-Duty SBR (9mm) is a compact short barrel rifle (SBR) built on SIG's proven MPX pistol caliber carbine platform. This 9mm SBR features an 8" barrel (1-in-10" twist) and an aluminum M-LOK handguard, delivering PDW-style performance in a package that collapses to just 25.75" overall. Backed by SIG's closed-bolt gas piston system, the MPX K Off-Duty cycles smoothly and reliably across a wide range of 9mm ammunition without gas adjustments.

This SIG MPX SBR ships with one 35-round magazine for 35+1 capacity, an optics-ready top rail with no factory sights, and a collapsible/folding aluminum-frame stock for fast transitions between compact carry and full shouldered use. Finished in matte black, the MPX K SBR 9mm  (WRMPX-8B-9-SBR-35, 798681687312) is an NFA-regulated short barrel rifle — all transfers must comply with applicable NFA procedures. Whether you're shopping for a home-defense SBR, an off-duty carry carbine, or a compact 9mm platform for range and training use, the SIG MPX K Off-Duty delivers SIG's reliability in one of the most maneuverable SBRs on the market.
