This 9MM Sub-Machine Gun (SMG) Fake Suppressor is as close to a real silensor as you can get without paying the tax stamp. Its CNC precision machined from solid aluminum with a durable hard black anodized finish identically to our real NFA registered suppressors. Since its a fake suppressor, the sound is not reduced and bullet impact is not changed. Many customers do prefer the weight and balance improvement that the suppressor provides. Its perfect for use on an UZI, STEN, AR15 or any other "sub-gun" with a threaded barrel and will also of course work on any 9MM firearm that has the barrel threaded 1/2x28.
