Bolt Switch

protrudes through its aperture in the face of the bolt

(6) Sear spring and sear. With the sear spring still wedged on the cocking lever, replace the spring, and insert the sear in its slot—stud up, and notch to the front. Make sure the sear spring is properly seated in its recess in the bolt, and the bottom of the sear (fig 36).

(c) Sear slide. Press down on the sear and replace the sear slide in its guideways. The slide may be inserted from either side, unless the gun is to be fired by the sideplate trigger. In that case, the square end must be to the left (fig 35).

(d) Sear pin and stop. Replace the sear stop and pin (accelerator stop and lock). Press down on the head of the pin (base of the accelerator stop) to force it in place (fig 41); swing the sear stop into its groove in the bolt.

(e) Cocking lever and pin. Replace the cocking lever, the rounded nose down and to the rear; the top of the cocking lever to the rear. Replace the cocking lever pin from the left side of the bolt. To test for correct assembly, cock the firing pin by rotating the top of the cocking lever toward the front of the bolt; then rotate it to the rear and depress the sear. This should release the firing pin.

(/) Bolt switch stud and bolt switch. Re place the bolt switch stud with the small end up. Place the bolt switch over the bolt switch stud, so that the groove marked "L" is continuous from the left-hand feed (fig 42). (The wider portion of the bolt switch will be to the front.) —-

(g) Extractor. With the extractor arm vertical, replace the extractor stud in the extractor pivot hole of the bolt. Rotate the extractor forward ; insure that the collar is engaged in its slot in the bolt (fig 43).

6. Barrel Buffer Body Group (Fig M).

(1) Disassembly.

(а) Barrel buffer tube lock assembly. Turn the barrel buffer body group upside down. Pry up on the barrel buffer tube lock latch, to disengage the latch before moving the lock body to the rear. Pry up the latch end of the assembly, so that the lug will clear the barrel buffer body. At the same time, press down on the front of the lock body to keep it from springing out. Turn the accelerator back to push the barrel buffer tube lock assembly out of its slot (fig 45 and 46).

(б) Barrel buffer body spring Jock. In most cases, the barrel buffer body spring lock is staked and will not be removed.

(c) Accelerator pin and accelerator. Drift the accelerator pin out and remove the accelerator. This completes detailed disassembly of the barrel buffer body group.

(a) Accelerator and accelerator pin. Replace the accelerator with the tips up and the claws to the rear. Replace the accelerator pin so that the ends are flush with the sides of the barrel buffer body group.

(5) Barrel buffer tube lock assembly. Turn the barrel buffer body upside down. Hold the assembly against the barrel buffer body, lug down. With the thumb of one hand, press the forward winged part into the circular opening in the slot. With the other hand, raise the rear of the assembly enough to lift the lug over the buffer body. Push the assembly forward until the rear winged part (barrel buffer tube lock latch) snaps into the circular opening in the slot (fig 47). This completes assembly of the barrel buffer body group.

c. Barrel Extension Group.

(a) Breech lockpin and breech lock. Drift the lockpin out and remove the breech lock from the bottom of the barrel extension group. The top of the breech lock may have a wide, single-beveled edge, or a double-beveled edge. In earlier models, the top may be flat (fig 50); the newer models
