Iv never had a problem with AA mags, iv got some ASC mags that can be problematic. But I use 20 round Pmags with 4 or 5 rounds in it, work snd feeds ok. The Elander mags from AA work good also. Check your gas block and cycle it some, let it brake in, should be ok. If you take the gas block off, measure the port diameter just to make sure its not undersized.
