MPX-SD Conversion

The MPX-SD Conversion from Ronin Arms transforms your SIG MPX into an integrally suppressed system built for subsonic performance using standard 9mm ammo. Crafted in Payson, AZ, this upgrade includes a 5.75″ ported barrel, an 8″ or 12″ Defcon4 SD suppressor, and Ronin’s signature TIG-welded, hand-fitted integration.

This is the same suppressor system featured in the MPX SD Full Build and Ronin Edition MPXSD-K—known for quiet operation, reduced blowback, and exceptional control. Built under the “One Gun, One Gunsmith” ethos for unmatched quality.
