SECTION V. REASSEMBLY
First, engage the front opening of the gas cylinder tube with the gas cylinder (fig 35). Then seat the rear of the tube into the rear sight base (fig 36). Rotate the gas cylinder tube lock down to its lock position (fig 37).
Replace the bolt: Slide the spindle of the bolt into the carrier (fig 38) and rotate the bolt to mate the operating lug with its cam path. Pull the bolt as far forward as possible in carrier (fig 39).
Replace bolt carrier: Slide the piston into the hole under the rear sight (fig 40) until the carrier fits into its cuts at the rear of the receiver (fig 41). Press the carrier down, with the bolt fully forward, and then slide the carrier fully forward (fig 42).
Replace driving spring: Insert the driving spring into its hole in the rear of the carrier (fig 43) and reseat the guide into its slot in the receiver (fig 44).
Replace the bolt cover: Insert the front end of the bolt cover into the circular grooves in the rear sight base (fig 45). Apply thumb pressure over the square hole in the rear of the cover (fig 46); press down and forward until the end of the driving spring guide snaps through the hole (fig 47).
