Alpha Shooting Sports 5.56 M-LOK9 Pitchfork Pistol Upper Review

Let’s Talk About Alpha Shooting Sports 5.56 M-LOK9 Pitchfork Pistol Upper

The Alpha Shooting Sports 5.56 M-LOK9 Pitchfork Pistol Upper is a complete upper receiver assembly designed for AR-15 pistol builds. Manufactured by Alpha Shooting Sports, this upper boasts a 10.3″ barrel, a 9″ M-LOK handguard, and a host of features aimed at enhancing performance and reliability. I’ve been building and tinkering with AR platforms for over a decade, and I’m always on the lookout for high-quality components.

My latest build required a reliable and compact 5.56 upper receiver for a dedicated truck gun. I needed something accurate, durable, and easily customizable with modern accessories. After extensive research and reading countless reviews, I decided to give the Alpha Shooting Sports 5.56 M-LOK9 Pitchfork Pistol Upper a try.

Upon unboxing, I was immediately impressed with the fit and finish of the upper. The anodized coating was evenly applied, and all components felt solid and well-made. The weight felt appropriate for a pistol upper of this size, suggesting quality materials were used in its construction.

I considered options from Bravo Company Manufacturing (BCM) and Daniel Defense, known for their exceptional quality, but their price points were significantly higher. The Alpha Shooting Sports upper offered a compelling balance of features and affordability. My initial excitement stemmed from the promise of a high-quality, reliable upper that wouldn’t break the bank.

Performance & Functionality

The Alpha Shooting Sports 5.56 M-LOK9 Pitchfork Pistol Upper performs admirably. Its accuracy is impressive for a short-barreled platform, easily achieving 2-3 MOA with quality ammunition. Reliability is outstanding, as I have yet to experience a malfunction attributed to the upper itself.

The upper’s strengths lie in its combination of quality components and thoughtful design. The M-LOK handguard provides a comfortable and versatile platform for mounting accessories. The main weakness is the lack of a muzzle device, which needs to be purchased separately.
