Shadow Systems MR/XR Barrel with Compensator Features The Shadow Systems MR/XR Barrel with Compensator is a drop in upgrade kit built for the existing MR920 and XR920 pistol lines delivering the same compensator assembly found on the factory MRP and XRP models. Chambered in 9mm the 4.2 inch barrel uses a Tri-Lug style attachment method allowing the compensator to be removed and reinstalled quickly without special tools. The all steel compensator is nitride coated for long term corrosion and wear resistance a finish that holds up well under repeated firing and cleaning. Because the compensator is designed to align with the contours of the factory slide the completed pistol presents a clean seamless appearance rather than an aftermarket bolt-on look. One of the standout design goals behind this kit is space efficiency as the compensated assembly is built to fit inside holsters designed for standard G17 sized pistols. That means shooters do not need to source a specialty compensator holster just to carry or compete with their upgraded pistol. Finished in a bronze nitride coating the barrel and compensator add a distinctive visual contrast against the pistol s existing finish while maintaining the same corrosion resistance as the factory black option. For MR920 and XR920 owners looking to add recoil control and a competition look to their pistol the Shadow Systems MR/XR Barrel with Compensator is available at GrabAGun as a straightforward bolt-on upgrade.
