First Thoughts on the ANGSTADT UPPER PISTOL CALIBER STRIPPED
The ANGSTADT UPPER PISTOL CALIBER STRIPPED is a component that sits at the heart of any pistol caliber carbine (PCC) build. It’s manufactured by Angstadt Arms, a company known for its innovative and high-quality AR-pattern firearms and components. The allure of this particular upper receiver lies in its versatility, promising compatibility with a range of popular pistol calibers and seamless integration with standard mil-spec lower receivers, offering a blank canvas for creating a custom PCC.
My interest in the ANGSTADT UPPER PISTOL CALIBER STRIPPED stemmed from a desire to build a dedicated 9mm AR pistol. I was looking for a reliable, yet affordable, upper receiver that wouldn’t break the bank but still offered the core performance needed for consistent range use and potential home defense applications.
Upon unboxing, the ANGSTADT UPPER PISTOL CALIBER STRIPPED exuded a sense of quality. The matte black hard-coat anodized finish was evenly applied and felt substantial to the touch. It’s a slick side design, lacking a forward assist or dust cover door, which contributes to its streamlined appearance and reduced weight.
Comparing the ANGSTADT UPPER PISTOL CALIBER STRIPPED to other stripped uppers on the market, such as those from Aero Precision or even some of the more budget-friendly options from Palmetto State Armory, the Angstadt offered a compelling middle ground. Aero’s offerings, while excellent, can be pricier. While PSA’s can be cheaper, there can be concerns around finish quality and consistent tolerances. The Angstadt seemed to strike a balance of quality and affordability. My initial impression was one of cautious optimism, excited to begin the build and see how it performed.
Real-World Testing: Putting ANGSTADT UPPER PISTOL CALIBER STRIPPED to the Test
First Use Experience
My initial testing of the ANGSTADT UPPER PISTOL CALIBER STRIPPED took place at my local outdoor shooting range. This was after I completed the build, pairing the upper with a dedicated 9mm lower receiver, bolt carrier group, and barrel. I wanted to get a feel for how the complete system performed under controlled conditions.
The range day started under clear skies, but the wind picked up later, introducing a crosswind. The ANGSTADT UPPER itself functioned flawlessly. There were no issues with cycling or extracting spent casings. The absence of a forward assist wasn’t missed, as the bolt carrier group consistently chambered rounds without issue.
The slick side design proved advantageous, preventing the accumulation of debris compared to uppers with a forward assist. Initial impressions were positive. The ANGSTADT UPPER PISTOL CALIBER STRIPPED seemed to be a solid foundation for a reliable and accurate 9mm AR pistol.
Extended Use & Reliability
After several months of regular use, the ANGSTADT UPPER PISTOL CALIBER STRIPPED has continued to perform admirably. I’ve put several hundred rounds through it, using various types of 9mm ammunition, including both brass and steel-cased rounds. The Angstadt has exhibited no signs of wear and tear beyond the typical cosmetic scuff marks associated with regular use.
The anodized finish has held up well, showing no signs of fading or chipping. Cleaning and maintenance are straightforward. A simple wipe down with a CLP after each range session is all that’s required. Compared to other upper receivers I’ve used in the past, the ANGSTADT UPPER PISTOL CALIBER STRIPPED has proven to be exceptionally reliable and durable. It outperforms some of the cheaper options I’ve experimented with and holds its own against more expensive alternatives.
