its an m4.
pull the trigger and the bolt slides forward and pushes the bullet into the breach, then a device inside fires the bolt back again and catches in the sear pin. doesnt actually fire anything, just got a bullet in the mechanism. magazine doesnt release, if it fires and doesnt come back again use the handle at the back of the carrying handle to re-cock it. the stock slides back by just dragging it, pull the button down and push in to close it back again. rate and comment
