American Built Arms Company Pro 5.56mm Firing Pin Review

Let’s Dive into American Built Arms Company Pro 5.56mm Firing Pin

The American Built Arms Company (AB Arms) is not necessarily the first name that springs to mind when discussing mission-critical AR-15 components like firing pins. However, the American Built Arms Company Pro 5.56mm Firing Pin promises mil-spec reliability at a budget-friendly price point, making it an intriguing option for both budget builds and those looking for spare parts. This review will delve into its performance, durability, and overall value, based on my extensive experience with AR-15 platforms.

A nagging fear of parts breakage on an older rifle that sees hard use spurred me to look for affordable and reliable replacement parts. I was specifically concerned about the possibility of a firing pin failure during an upcoming multi-day training course.

The American Built Arms Company Pro 5.56mm Firing Pin arrived in simple packaging, a no-frills approach that aligns with its price. The AISI 8740 steel construction and chrome plating were immediately noticeable, appearing well-machined and finished. It felt solid in hand, instilling a sense of confidence.

I considered several other options, including firing pins from established brands like Bravo Company Manufacturing (BCM) and Daniel Defense. While I trust those brands implicitly, the price of the AB Arms pin was significantly lower, making it worth a try for a back-up role. My initial excitement was tempered with cautious optimism, eager to see if the price reflected a compromise in quality.


Real-World Testing: Putting American Built Arms Company Pro 5.56mm Firing Pin to the Test

First Use Experience

I first tested the American Built Arms Company Pro 5.56mm Firing Pin at an outdoor shooting range during a carbine course. The conditions were varied, ranging from bright sunlight to light rain, exposing the pin to different environmental factors.

The firing pin was installed in a spare bolt carrier group (BCG) and used in a 5.56mm AR-15. Installation was straightforward, with the pin fitting perfectly within the bolt. There were no noticeable issues with primer strikes.

There were no issues to report after the first few hundred rounds. The rifle cycled reliably and consistently, even when exposed to the damp conditions.

Extended Use & Reliability

After several months and approximately 1,500 rounds, the American Built Arms Company Pro 5.56mm Firing Pin continues to perform reliably. I’ve observed no signs of abnormal wear or damage.

Regular cleaning and lubrication, following standard AR-15 maintenance procedures, have kept the pin in good working order. The chrome plating appears to be holding up well, preventing rust and corrosion. It outperformed my initial expectations, showcasing impressive durability for its price point.

The AB Arms firing pin has proven to be a reliable drop-in replacement. It instills more confidence than the original firing pin in an older BCG that has a much higher round count.
