My anxiously awaited Grendel upper assembly arrived today. Using Hornady Black 123 gr and Federal Fusion 120 gr. with 4 round e-lander mags. Feeding problems which I suspect maybe related to the mags. With a single round, the rifle will cycle properly and lock back on the empty mag. When the mag is loaded, the fired cartridge will not fully ejected and the loaded round appears to hit up against the front of the mag. I see from other posts that this is common with other manufacturers mags but I haven't found anything on the 4 round e-landers. Any suggestions?
