I just finished my AA XLP new upper build and the magazine won't seat with the BCG forward. With BCG back the magazine locks but then the bottom of the low mass carrier won't pass the magazine going forward. It's also a AA upper (no bushing) receiver. I tried 3 different mags (magpul,mft,hexmag) and 2 different lowers. HELP??? Jeff

I tried it with a different carrier and magazine seats. Just wondering if AA had a bad run of low mass carriers?? Piston carrier key would solve problem but I'd like to use AA carrier or return for refund. Jeff

Have you tried contacting Adams Arms?  They have pretty good CS, should get you squared away.

Contact AA as the op said they have great CS. I have the XLP system with Low mass carrier purchased in early "16" and it runs flawless with 4 different brand mags that I have here, all seat and function perfect.
