P/n 2300-008 is now AS2250-025 in the latest EVP, has front screw. P/n AS2250-A013 has rear screw.
I cannot say if -008 is still a good number.I don't have one in front of me but going by the EVP, the hole was in the front on -008, same as -025. Don't know why the number was changed.
I did some more research. It looks like crosman did not change the EVP drawings to show the new rear screw location. Just a different part number for the rear screw breech. We know the newer pistols have the rear screw location. I can't find a drawing that actually shows the rear screw location.
