I am in the process of assembling a aero gen2 lower. Bcm enhanced Lpk, Bcm buffer kit, Troy ambi-mag release and a seekins ambi safety. My question is, will a Rra left hand upper work on the lower? I know a Stag will. What are some other left hand uppers out there that would be worth considering? Timing has really messed things up with the current situation. I wanted to have this finished by November but now I may have to speed it up. The lower is complete. Thanks for any advice. This is being built for my son. It's "his" first Ar. I have a pretty good assortment including a Tavor which the brass clips him in the chin. Lol thanks again for any advice.
