4. Place the hook (6) of the bolt disassembly tool (5) into the disassembly notch (2) on the firing pin cap (3) and pull the

handle (4) to compress the firing pin spring.

5. Screw in firing pin assembly (1) until the cocking leg is fully seated and in the fired position to the back of the bolt body

assembly (7). Ensure the firing pin protrudes from the bolt face, then measure firing pin protrusion.

6. Inspect the firing pin (1) protrusion using the firing

pin protrusion gage (13) inside the bolt face (12). The

firing pin protrusion is correct if the gage hits the fir-

ing pin on the 0.044 minimum and clears on the 0.060

maximum. If the protrusion is too short or too long,

replace the firing pin assembly.
