silencer, to file down a serial number. we do for now. we don t know what will happen with silencers. a bill was make its way through. we will see what happens with that. this device is not illegal. as we pointed out in the earlier selling isment, this device is designed to put down suppressive fire. heats what it is. what the killer did is used it for plunging fire. he could pull the trigger one time. he was in a position, elevated position. and the rounds basically go out in an in direct fashion and rain rounds down. the military went to a three-shot burst because they understood it is not a direct fire weapon when it s on on fully automatic, you cannot control it. you are firing at an area. why would a civilian need a device about that? it is about want these days when it can pomes to weapons, n need.
