Description
The Sig Sauer MPX SBR pairs a closed-bolt gas piston system with a 4.5″ cold hammer-forged barrel for reliable, low-recoil 9mm performance in a compact, NFA-regulated short barrel rifle. The minimalist folding stock and M-LOK handguard keep the package light and easy to maneuver. NFA rules apply — requires ATF Form 1/4 approval and tax stamp before transfer.
