When you need to finish off your next build or upgrade your current rifle, our AR15 9mm Socom Fake Suppressor should be your next piece! It can be used either as a shroud to go around the barrel or it can be used as an extension for the barrel (E.g. when your hand guard extends past the end of your barrel and you want the PDW integrally suppressed look). To install, simply tighten down the thread protector (with a crush washer), then at each end it is tapped for 4 set screws to lock it down in place.
