I have a new MCK Gen 2 for the glock platform pistols, 17,19, 19x, 22, 23, 25, 31, 32, 45. Has brass catch installed that is removable, flashlight, thumbstops, and pistol brace installed. Aluminum pic rail for accessories. This does not turn your firearm into a sbr due to the brace. Put a red dot on top of it and its good to go! Super accurate and reliable.holds an extra mag in the from for reloads or to use as a hand stop. Entire set up fits in a backpack. Can run with a silencer. Perfect for a home defense gun that you want to stabilize and be more accurate with. Must meet in Inver Grove. Silencer and optics not included.
