  1. J. (verified owner)

    Functioned flawlessly. Angstadt UDP’s have the best overall features (IMHO) available for marketplace AR-9’s and their execution of this product was top tier.

  2. M.

    This review is for the UDP-9 10.5 inch pistol. Fit and finish of the product is flawless (and as good, or better, than some of my more expensive traditional ARs!) Functions flawlessly, beautiful craftsmanship. Additionally, customer service responsiveness (I had a warranty question) is excellent, almost immediate. This pistol is the envy of my group of shooting buddies!
