Help! My Tavor-21 elite series airsoft gun has a problem. I don't know if this is part of the gun, but the electric blowback system has stopped working. The gun works fine, but the blowback isn't working. The bolt is always in the closed position, except for when I manually open it with the charging handle. It is supposed to go back every time a round leaves the gun. Any help? TF9 Operators don't die, we just go to hell and Regroup.
