Great 9mm AR
Got my UDP-9 a few months ago and I love this gun! Fit and finish is great. There is no play between the upper and lower like some of my other ARs. Doesn't like my ETS mags but everything else works fine. I haven't had a single issue and this this runs like a sewing machine.

Would not recommend this pistol to anyone. Customer service and the pistol was a total disappointment. Do not buy!
Had FTE issues out of the box. Tried all my oem glock mags(G19 and G17) plus several aftermarket mags. All had issues. Used 4 different factory ammo brands from 115 gr to 147 gr. Still had fte's. Contacted Angstadt Arms explaining the fte issue and all the different ways i tried to fix it myself. I noticed the ejector had a lot of play up and down and side to side. Asked them if it was supposed to be tight or a little play. Asked them if it could be the extractor. All asked using email because they do not answer phone calls and would not return my calls. They sent me an email asking if the fte's were chamber or breech. That was the last i heard from them. They never answered any of my questions, never tried to call and talk to me on the phone, never offered any solutions. Overall, the whole experience sucked. Should have bought a PSA ar9 or Cmmg Banshee.
