Hey Fab, acouple of things you should check is to make sure that your cradle piston is centered when installing it on the bolt carrier. Screw is loctite as well. Check the o-ring on the cradle piston for proper lubrication and seal. Unfortunately with gas guns you will get fps deviations of 10-50fps which will affect your shot to shot accuracy/range. Depending on you play style, the faster you shoot the colder your mag in turn it will affect range/fps. Lay off the silcone, clean your barrel and hopup rubber with warm dish soap. I suggest doing the Top down hopup mod if you want any kind of respectable range and consistency combo with a blue ra-tech rubber and barrel. And use .28-30's but you will have a problem with not being able to overhop them if you dont have the mod done.
