“The actual receiver is very nice and obviously high quality. The upper parts were not. The dust cover was especially poor. It has a very low price, so it was not completely unexpected. If i could do it all over again I would probably just buy a stripped upper.”
“I bought the Gen 2 upper to fit on an existing Aero lower I had. My milspec upper receiver was from an older build and just did not mate with the Aero lower well. There was lots of joggle and wobble and I decided to fix that. The Gen 2 upper mated perfectly with the lower and the tolerances against my Faxon barrel were perfect. I am very happy I chose this upper over another milspec receiver.”
“It matched up well to my Anderson lower. I installed a BCM charging handle and bcg. Both fit well. I haven't installed a barrel yet but do not foresee any problems with that either. Quality product. I would buy again and recommend others to buy.”
