Let’s Talk About Angstadt Arms Angstadt Upper Receiver Pistol Calibers 9mm/40sw/10mm/.45acp
The Angstadt Arms Angstadt Upper Receiver Pistol Calibers 9mm/40sw/10mm/.45acp offers a unique solution for AR-15 enthusiasts looking to diversify their pistol caliber options. Manufactured by Angstadt Arms, this upper receiver allows you to build a dedicated pistol caliber AR-15 without the complexities of modifying a standard upper. Its compatibility with multiple pistol calibers is a standout feature, promising versatility for various shooting needs.
For years, I’ve been piecing together AR builds, experimenting with different configurations. I needed an upper receiver that would allow me to shoot pistol calibers reliably and accurately in an AR platform, without sacrificing the familiar ergonomics. The Angstadt Arms offering seemed like the ideal solution.
Out of the box, the Angstadt Arms upper receiver feels solid and well-made. The hardcoat anodized finish gives it a robust appearance, and the 7075-T6 billet aluminum construction suggests excellent durability. The weight feels appropriate for an AR upper, neither too heavy nor flimsy.
I considered other options like complete pistol caliber ARs from various manufacturers and even some dedicated pistol caliber uppers from smaller companies. However, the multi-caliber capability and reputation of Angstadt Arms swayed my decision. The ability to swap between 9mm, .40 S&W, 10mm, and .45 ACP with the appropriate lower and magazines was a huge draw.
My initial impression was one of excitement and cautious optimism. I was eager to see how it performed with different pistol calibers. The build quality was immediately apparent.
Real-World Testing: Putting Angstadt Arms Angstadt Upper Receiver Pistol Calibers 9mm/40sw/10mm/.45acp to the Test
First Use Experience
My first range trip with the Angstadt Arms Angstadt Upper Receiver Pistol Calibers 9mm/40sw/10mm/.45acp was dedicated to the 9mm configuration. I paired it with a dedicated 9mm lower receiver and several Glock-compatible magazines. The range was an indoor facility with controlled lighting and a solid backstop, perfect for testing accuracy and reliability.
The performance was surprisingly smooth, with minimal recoil and consistent cycling. I ran about 200 rounds of various 9mm ammunition types (115gr FMJ, 124gr JHP, and 147gr FMJ) through it without any malfunctions. The ease of use was noteworthy, as the upper receiver integrated seamlessly with the AR-15 platform, feeling intuitive and familiar.
The only minor issue was adjusting to the blowback operation, which felt slightly different than the direct impingement of my standard AR-15. However, this was easily overcome with a few magazines.
Extended Use & Reliability
After several months of regular use, including a couple of outdoor range sessions in slightly dusty conditions, the Angstadt Arms Angstadt Upper Receiver Pistol Calibers 9mm/40sw/10mm/.45acp has proven to be remarkably reliable. There are minimal signs of wear and tear on the receiver itself, with the hardcoat anodized finish holding up well. Cleaning and maintenance are straightforward, requiring only a standard AR-15 cleaning kit and some solvent.
The .45 ACP configuration required a different lower and magazines. I found the performance equally reliable, although recoil was understandably more pronounced. Compared to other pistol caliber AR platforms I’ve used, the Angstadt Arms upper provides a more consistent and accurate shooting experience.
