Tear-Down:
- Move the cocking pin to the lower (fired) position. This will take the tension off the firing pin spring and drop the cocking indicator so you can remove the BAS (bolt assembly screw)
- Remove the BAS
- Make sure the cocking pin is in the lowered position, which should expose the front of the firing pin spring through the ramped port in the bolt body. Using a small screwdriver, push the spring rearward then pull out the cocking pin. The pin has a groove in which the tail of the spring engages to retain the pin, thus the need to push the spring rearward.
- Remove the firing pin/spring assembly from the bolt body
- Remove the Bolt Head Retaining Pin by pressing it out in either direction to remove bolt head from bolt body.
Assembly:
- Insert bolt head into bolt body, making sure the "flats" on both are aligned, and insert the bolt head retaining pin making sure the hole is properly aligned to allow the firing pin to pass through.
- Reinstall the firing pin/spring assembly into the bolt body
- Reinstall the cocking pin through the firing pin. It may be necessary to push the firing pin spring rearward to allow the pin to pass through.
- Reinstall the BAS.
- Flip the cocking pin to the cocked position.
