    "Awesome mock silencer, worked good to conceal my longer barrel. I added multiple sectional layers of foam on the interior of the silencer. After I was finished, my gun is practically silent in terms of the sound emitted from the barrel.

    "If you want a silencer that really works, this is it. It works with both clockwise and counterclockwise, and this actually quiets the gun. This silencer is lined with foam, it never gets in the way, but completely removes the snap of air that comes from every shot. Beyond lightweight, it weighs nothing. A little long but it works great!

    "WOW this thing is huge, got this for my LM4 and it just makes this thing look deadly, very light weight. Only thing that bugs me is I havent been able to remove the threads on it and swap it for cw threads as it seems to be on there very tight.
