Sounds like the grendel in a AICS mag night be a feed lip issue, tried loading a single round in the magpul .308 mag and spacing it correctly in the mag and the feed lips let the nose of the bullet rise higher then it should and jammed. Might have to tweak the feed lips on my mags when I get them if there is a feeding issue, hopefully it's just the gap of the feed lips that's the issue and not the length as the feed lips themselves, the factory AR mag feed lips extend slightly further forward then the feed lips on the magpul .308 mag. The AR mags feed just fine in the factory predator stock.
