BUY IT!!!! Review by Nick

I purchased my upper over Labor Day weekend and got it that Wednesday. Fast shipping and was in great condition. Also, I'm not sure if it's included in every order or just a gift but I was also send an armorers wrench. I've put 200 rounds through it yesterday and it was great! Only flaw I would mention is the packaging was very bland but nothing major and I would like the engraving "A" for Aero precision on the hand guard bigger or painted just for show. Overall great product (Posted on 9/11/2017)

Finally got to fire this bad boy. LOVE IT! I had bought the FDE lower from Aero and after hemming and hawing over what dress to put on it like a school girl (couldn't decide btwn 223 Wylde or 300) I put my big boy pants on got the 300. Awesome! Barely kicked as far as I felt and functioned like a champ. Beautiful fit n finish and the boys at the range were jealous. Will save my duckets for the Wylde upper next. Would go the 308 lower and upper next but missed my window. CA sux. Must move! (Posted on 12/28/2016)
