This is a complete M4 blank firing upper receiver group for the M4/AR15/M16 family of weapon systems. It is to be used with our milsim blanks and will not function with M200 milspec blanks as they are under powered. Note that this is still dangerous as within close range it can cause injury. These uppers should only be used with SAFETEAC MAGS to prevent the use of live ammunition. The upper does not come with any blanks, magazines or a charging handle and bolt carrier group. Please allow 3-4 weeks for your upper to ship since each one is made to order.
Produces a very loud bang similar to a live round and a significant flash, especially under low light conditions. Uses a standard bolt carrier group and charging handle.
