Bought a blem upper. Not sure where the blem because it looks perfect to me. The staff I spoke with were friendly and extremely helpful. I used thier upper on a different brand lower. Previous to using this upper I could get through an entire magazine without having to clear two or three malfunctions. The proprietary oversized ejection on the qc10 upper was the solution. I wish I had the entire qc10 package.

Bought the 9mm glock variant several months ago, 5.5 barrel Have put maybe 700 rounds downrange to date. Added a Trijicon MRO and Rise Armament trigger. I originally saw these at a demo day and have wanted one since. Love it, very well suited for home defense which is why I bought it. Easy to handle, reliable, very consistent.

Upper and lower receivers of the highest quality! If youre building a pistol caliber AR then youre on the right website.
