Both manuals are about 3/4 way down toward the bottom. Hope this helps.

Life sucks. Take it to a gunsmith or send it back to the factory for re-assembly.

well for starters, there is no firing pin, second, without major machinery, you can't fix a spring powered air rifle, any of them. It is impossible, major jigs and fixtures hold these things while the spring is removed and replaced. You might try crossman, they do a lot of repairs.

what is the fps of the crossman m4 .177 pellet rifle with the 5 pumps they tell you to use in the instructions?

yes it safe to shoot bb,s in the 1377 pump pistol,i have 3 of them they actually shoot true'er and with more vilocity

Time to buy a new model. I had 2 of those with similar problems and couldn't find parts. Try the CO2 model 1088. I'm happy with mine. Spray the seals with silicone spray monthly or every 2 cartridges.
