How disassemble glenfield model 778?

Answer 1

Start by ensuring that the gun is safe and the chamber and magazine are empty. To unlock the chamber without pulling the trigger you must engage a lever on the front of the trigger assembly in the loading port opposite the magazine. Once gun is safe and empty, slide the action halfway to the rear or open. Unscrew the magazine cap and remove it and the barrel. On either side of the gun locate the trigger assembly pins, drive those pins out with a punch. Remove trigger assembly by pulling up and towards the stock. The L shaped action release lever may fall off of the trigger assembly at this point. It simply sits back into a groove on the side of the trigger assembly when you reassemble the gun. Now find the shell stop rod on the inside of each side of the receiver and remove them, They may fall out or may a gentle pull if dirty. Now move the action forward again or closed. Look on the walls of the receiver where the trigger assembly used to sit near the rear. You will see an identical piece on each side that are the rails of the shell lift arm. These rails are held in place by small pins that they fit onto. Gently pry them from these pins using a small screwdriver. They should remove easily. Once they are loose, Gently slide the action open again. Now holding the the other end of the shell lifter so as to line it up with the breech or action opening, slide the action forward removing the bolt, bolt carrier, and shell lift arm. As these clear the receiver to the front the forearm rails will pull clear of the receiver and slide off of the magazine tube. Dis assembly is now complete. Reassembly is the opposite making sure the you align the shell lift arm, the bolt, and the bolt carrier so that they enter the receiver simultaneously.
