Radical 7.5” upper - Radical Firearms Upper Assembly 7.5 inch 5.56 M4 Contour, A2 Flash Hider

I got this upper at a great price. So far I’ve run a little over 200+ rounds through it, and it functions flawlessly with a variety of ammo and magazines. I was surprised at the accuracy it has out to 50 and 100 yards for such a short barrel. Definitely worth it, I would recommend this upper.
