Great buy Review by Simon
I ordered this set for a 7.5" pistol build and am extremely happy with the quality and price. I would definitely recommend this upper and handguard to everyone. I have assembled many AR pistols/rifles over the years and typically used budget/ bulk receivers but never really liked the end result as it felt cheap. I paired this to an aero lower and the connection is very tight. The finish on the upper and lower match perfectly color and quality. Great buy. (Posted on 2/10/2018)
