To remove the backplate assembly, refer to figure 13-37. Two conditions must exist before the backplane assembly can be removed. First, the bolt latch release must be up and free of the bolt latch release lock. If it is not, push down on the bolt latch release (fig. 13-37, view A). Turn the buffer tube sleeve to the right. Keep turning until the bolt latch release lock is free of the bolt latch release.

The second condition is that the bolt must be forward. If it is not, depress the bolt latch release. At the same time, use the retracting slide handle to ease the bolt

forward. When the bolt latch release is up and the bolt is forward, the backplate assembly can be removed. Located below the buffer tube sleeve are the backplate latch and latch lock Pull out on the latch lock and up on the latch, as shown in figure 13-37, view B. Remove the backplate by lifting it straight up.

Remove Driving Spring Rod Assembly

The driving spring rod assembly consists of its inner and outer springs and a rod. The assembly is located next to the right sideplate inside the receiver (fig. 13-38). To remove the assembly, push in on the head of the driving spring rod. Push it to the left and remove the driving spring rod retaining pin from its seat in the right sideplate. Full the complete assembly to the rear and out of the receiver.

Use caution when removing the driving spring rod assembly. You should feel a slight pressure on the springs when the bolt is forward. Never attempt to cock the gun while the backplate assembly is off and the driving spring rod assembly is installed. Cocking the gun compresses the spring group. If the retaining pin slips from its seat, the rod will come flying out! Anyone standing behind the gun could be injured.
