This is an AR15 / M16 Under Flash hider Blank Firing Adapter. You can fire and chamber blanks with this little brass device. It goes down at the end of barrel and then you screw back on your flash hider which sandwiches in the device. Absolutely not visible. (Been used in the movies for years) It has a reduced exit hole to let some gas escape but holds back enough to build back pressure to chamber the next blank. Will run in semi’s and full autos. Will also fit numerous rifles besides the AR – M16 platform. Basically any 5.56 or 223 that has a threaded flash hider or muzzle break and runs standard M200 Blanks. This product has a flat shipping fee of $5.00 no matter how many you order.
