Oh forgot about the Uni-Mag. One of my ASC 25 round 6.5 Grendel mags failed to feed from the non ejection port side. Comparing the feed lips to functioning mag showed the inside feed lip was in a different position. I used a pair of pliers to bend the feed lip to match my good mags and it has since fed fine. The ASC mag bodies are not has heavy gauge steel as E-Lander mags and more easily deformed.
Overall I’ve had good luck with 6.5 Grendel mags. Feeding issues in the 6.5 Grendel can be caused by gas issues, ejector, extractor or feed ramp issues to where you think it’s the mag but actually a different problem. One advantage of having access to multiple rifles. If the problems moves with the magazine it is probably the magazine. If the magazine only fails to function in one AR-15 it might not be the mag causing the problem.
