- 1). Slide the firing pin spring over the firing pin. Be careful not to compress the spring as you slide it on. The spring should fit snugly against the metal bushing at the rear of the firing pin.
- 2). Insert the firing pin into the center of the raised bushing on the back of the breech bolt slide. As you slide the firing pin forward into the breech bolt slide, the firing pin spring fits over the raised bushing. When the spring comes to rest against the back of the breech bolt slide, stop pressing forward on the firing pin.
- 3). Place the firing pin collar over the front of the firing pin and slide it back until it fits into place against the front bushing of the breech bolt slide.
- 4). Slide the extractor spring over the firing pin and press it back until it comes to rest against the firing pin collar.
- 5). Insert the extractor into the extractor notch on the right side of the breech bolt. Slide the breech bolt over the firing pin until the notch on the rear of the extractor catches on the front of the extractor spring.
- 6). Insert the cam pin into its mount in the bottom of the breech bolt slide. Take care to align the two indentations on the cam pin with the front and rear of the bolt assembly.
