Angstadt Arms UDP 9 – 9mm AR Pistol Review!

 

Is the Angstadt Arms UDP 9 (AR9) 9mm AR Pistol the ultimate pistol caliber carbine (PCC) that takes Glock mags? In this video, we’re doing a deep dive and complete review of my custom 9mm AR Pistol setup, from the range to the workbench. We’ll test its reliability with different magazines (OEM Glock, Magpul, ETS) and see how the last round bolt hold open (LRBHO) performs. I’ll show you every part I used in this setup, including the incredible Hiperfire 24C trigger, the Strike Industries parts, and the eye-catching blue components from Tyrant CNC and PC Armament. If you’re thinking about setuping your own AR 9 pistol, this is the guide you need to see!
