Title: Barrel indexing mod
Post by: Froggy. on October 05, 2012, 07:39:54 AM

Some pics of my Crosman 1377 pcp mod for quick barrel changing and indexing.

ptfe tape on the grubscrew to prevent a air leak. Barrel retention screws now on the side of the receiver ....so no need to remove scope when changing /indexing barrels.

Looks like it should work just fine.... I guess it requires a longer probe on the bolt as the pellet is further ahead of the transfer port.... Any problems on getting enough bolt travel?....

I like it. I've been thinking of something similar. Keep us updated.

Correct I needed to increase bolt travel because I could not make the part any shorter due to the retention screw position.
