The most common problem is seating the front bolt all the way back against the power tube before you instal it. Make sure that you leave it about a quarter inch in front of the power tube when you screw the regulator block to the aluminum reciever. Once that's done THEN put your spring and barrel in. You should hear a click as the bolt slides past the sear if you did it correctly.
