I just bought this SLG used and when I air it up it cycles and everything but air leaks out of the breech in huge amounts. Anyone know what this could be? I'm new to electros so any advice is appreciated.
This can also happen if you have something preventing the bolt from blowing all the way back and catching on the sear. This might from a bad oring and not sealing, debris getting stuck in the bolt, or not enough lube.
