Sterling Mk4 L2A3

When they did them here they cut the breech block at an angle from the outside front to the rear towards the mag housing. Then it's welded in place. The barrel must be plugged with a hard rod, front cut to an angle to deter driving out. Weld in place and pin from the outside, weld over that. The front screws are filled with weld. The trigger mech is removed and welded solid, then ground flat. The lock screw is welded in. The butt will likely not move because the rear cap will also be welded in place. Decide which mag you want in place because it must be reduced to 5 rds or welded inoperative, welded in place...

Pretty grim, then someone wants big money. The old cock and clicks were looking good...
