Anybody have any luck with the misfeeding problem yet? I've tried lubing the mags which seems to make it better but my echo1 ebr still misses the first shot always (semi or full auto) and about 8/10 shots dont fire on full auto. I use the two mags it came with and a mag that came with my agm m14. Is it the gun or the mags? Also anybody else have a problem with the little latch that allows you to move the cheek rest coming out very easily?
