    Solid build, timely delivery. I sent my Angstadt upper receiver off to Rudy at Macon Armory to have him build it into a complete Direct Impingement .45 upper with an 11” barrel. I will be getting it back next week and it will go on my Angstadt Arms 1045 lower to complete the build. I can’t wait to take it to the range!

    I just finished the upper receiver utilizing your buffer spring set, bolt carrier and upper receiver. So far so good. A quality product. I pick up my lower from my FFL this weekend and finish the build. I am looking forward to taking it to the range. Thanks again for great customer service and a quality product.

    The stripped upper is great. I had purchased the stripped lower receiver long before, and the match is great in terms of finish and color.

    I’m very happy with the purchase!

    A perfect match for my Angstadt lower. My original build had a standard AR upper. Looks complete now and fits perfect!!

  7. Jordan (verified owner)

    Bought this upper to go with my Jack9 lower I recently purchased. Just got the rest of my parts in so I could start putting it together and took good look at it, and it’s got a couple scratches in the finish reason for 4 stars. I also bought a bcg to with the upper that was flawless. Everything pieces together nicely.
