My VSR10 has developed two particular issues.
First, it is consistently been chronographing low for a M150 spring with in a few shots of a new bucking installation my velocity drops from 498 to 420 fps with .20 gram. BBs (all replicas MUST chrono with .20 at the fields I play at, then I switch to .30 on the field. This, I am sure is a blow by issue at the bucking. Towards this end I have acquired and installed NOOBIE'S anti blow by rings on a brand new 9ball purple bucking. I have not had a chance to re chronograph the replica so with finger crossed this fixes the air leak.
My second issue is more insidious. The replica is consistently firing to the upper right hand of my sights, far enough out that I can not adjust the scope to counter it. I am thinking it is a issue with the hop up chamber or mechanism but looking this over I do not see anything out of whack. The BB flies fairly straight out to about 150feet then instead of a "float" that a normal hop gives a BB it curves upper right. Once in a while I'll get a screwy BB that does its own thing but I have to be missing something as it is to consistent not to be something I can adjust out. I am thinking that the hop up arm is coming down with inconsistent pressure on the bucking Opinions? This developed maybe 500 Bbs ago, it does not matter what BBs are fed through it. I have tried excel, KSC, madbull SGM and Tm in weights between .20, .23, .25 .29 and .30. The bucking is correctly installed, the nubbin is centered appropriately and I am at a loss right now.
My build as it stands is this:
