Spring recommendations? low velocity on full body FLE
I've had this gun for a while now, at first it seemed to work fine once I shimmed the LPR. Now I can't seem to get my velocity up no matter what spring set or hpr pressure I use. I'm using an inception hard face bolt, inception hammer, high flow valve (looks like a rat valve). I have a madman spring set (valve and hammer spring) and the stock springs. I also have a reg tester and IIRC I'm at about ~300 now. I've tried pretty much every spring combo and can get it to work for a bit sometimes but eventually I can't get the velocity up to where I want it.
The only other problem I can think of is the o-ring on the tip of the HF bolt flies off after a few shots so I can't really use one.
