  1. Aaron A. (verified owner)

    Very happy with it. Really enjoyed the 44% off sale. My only complaint is that i didn’t get the 6” upper also and the sale is over 🤷🏼‍♂️

  2. Jack L. (verified owner)

    This upper is incredibly nice and the fit and finish is very good. It was between this upper and one from cmmg and I’m beyond happy with Angstadt. I threw a red dot sight on it and I kid you not first 2 shots were nearly touching I never had to sight it in. This is my first ar style build and couldn’t be happier thank you so much Angstadt.
