Pump rod/arm rubbing frame

Hey guys,

My autococker has been setup as a pump for about a year. Last night I put the pnuematics back on and it seems that the pump rod is touching/rubbing the body more than I remember. There is enough resistance that if I point the gun at the ceiling, gravity wont make the back block come away from the frame.

Do you guys think my pump rod got bent or is this normal?

It's usually pretty normal. More often than not that friction comes from the bolt and not the pump arm.

Make sure your front block is lined up straight, and that your bolt is nice and clean with fresh o-rings, if it has them.

if there are o-rings on the bolt, put a drop of oil on them.
