Hey Guys,
Recently acquired this gun in a trade. I was super excited.. except it's full of issues.
Basically - gun will fire semi auto perfectly fine. Full auto is a different story. It has difficulties feeding, the nozzle will get trapped in the hop up unit and the the bolt will move back and forth. Gas consumption is also horrible.
Here's a video:

Here is what I've done:
3 different bolts, 3 different trigger boxes (all combos) (From Ra-tech and We)
Different hop buckings (Ra-tech, Maple leaf, stock)
Machined nozzle to not make contact with the hop chamber (on the edges and feed ramp thing). Also modified the bottom of the nozzle to make minimal contact with the mag feed lip.
Modified the bolt for less resistance over trigger (Changed angle of ramp, polished to 0.5micron)
Modified bolt for less resistance over buffer spring retention pin thing. (The
little pin that holds the buffer in). Again, changed angle of ramp, polished to 0.5micron
Different weights of buffers and buffer springs
Different buffer bushings
Modified maglips for less resistance against nozzle

I put brand new ratech parts in it, still had the issues. I've tested the parts in another we m4, it worked flawlessly. So I have no idea what's going on. I'm going to assume to receiver is out of spec. But I don't even know if that would be a possibility.
Guy I traded refuses to do anything about it. He told me it worked and it didn't. And rather than driving to Northbay to kick his ass, I'd like to figure this out.
Thanks,
Josh
