Set-up:

Rainmain 229 kit
Luke's milled rail and body


Everything works, and can cock and fire in pump mode, but it's really takes a lot of strength to cock. There is heavy resistance somewhere.

If I loosen the bolt that attaches the Rainmain apparatus to the rail, then the pump shaft arm glides without resistance, but the whole thing is flimsy, and it doesn't cock.

I tried a washer between the rail and pump back bumper, but then I couldn't get the pump rod shaft to connect with the bolt correctly and it wouldn't cock.

Thank you for your thoughts.
