VSR-10:New NEO Piston Problem
 

Hi! I've just ordered a laylax NEO piston and a spring guide stopper. I received it today and when I tried it, the bolt pull was scratchy and the push was hard to push. I tried to put back the stock piston and it was working fine! Help anyone know the problem?

Now guys, The bolt pull is still very scratchy. It is not as hard to push anymore, but it is still really scratchy =(

I was thinking it may have been your spring is not aligned properly and that it's rubbing against the side of the cylinder causing a hard bolt pull/push. However, that shouldn't happen if you didn't have an issue with the stock piston in and I may be wrong as I've never owned a neo piston.

You notice any damage done to the spring, guide, piston, or sears?
