Great quality at a great price Review by BARRY M.
Came in a padded box, great qulity on finish and looks great specialy the rail fitment. Great fit with my Aero lower. Got the upper on sale with 15% discount along with Aero nitride BCG and Radian LT charging Handle. My complete Built cost me around $850+( with a VG6 Gamma upgrade and a Luthar MB3 stock). Cant wait to shoot it and reload some ammo . Thanks Aero for the deals. (Posted on 7/12/2018)
