First Impressions of Obsidian Arms AR-15 Firing Pin Retaining Pin
The Obsidian Arms AR-15 Firing Pin Retaining Pin might seem like a small, insignificant part, but any experienced AR-15 builder knows its crucial role in maintaining the rifle’s functionality and safety. The Obsidian Arms offering, a 5-pack retailing for a modest price, promises quality and reliability for new builds or replacing worn parts. Having disassembled and reassembled countless AR-15s over the years, I understand the importance of even the smallest components, and I was eager to see if these retaining pins lived up to the Obsidian Arms name.
My primary motivation for trying these retaining pins stemmed from a recent experience at a rifle training course. During the course, a fellow shooter experienced a broken firing pin retaining pin, leading to a temporary rifle shutdown. It highlighted the vulnerability of this small part and the importance of having spares on hand, prompting my search for a reliable replacement.
Upon receiving the Obsidian Arms AR-15 Firing Pin Retaining Pin 5-pack, I was immediately struck by their uniform finish and seemingly robust construction. The pins are small and black, as described. They appeared well-machined without any noticeable burrs or imperfections, giving an initial impression of quality control. Compared to some no-name brands I’ve encountered, the Obsidian Arms pins exuded a sense of confidence.
I was specifically choosing between these and similar offerings from CMMG and Brownells. I opted for the Obsidian Arms based on the positive user feedback regarding their durability and value for money. Additionally, the fact that they’re made in the USA was a significant factor.
My first impression was one of cautious optimism. These pins looked like a quality product. I was eager to test them out in a few of my builds and range rifles to see how they performed under real-world conditions.
Real-World Testing: Putting Obsidian Arms AR-15 Firing Pin Retaining Pin to the Test
First Use Experience
My initial testing ground for the Obsidian Arms AR-15 Firing Pin Retaining Pin was at my local outdoor shooting range. I installed one of the pins in a newly built AR-15 pistol chambered in 5.56 NATO. The installation process was straightforward and identical to that of any other firing pin retaining pin.
I put about 200 rounds through the pistol in varying conditions. The conditions ranged from bright sunlight to light rain, with temperatures hovering around 60 degrees Fahrenheit. The Obsidian Arms retaining pin performed flawlessly. It kept the firing pin securely in place throughout the session. There were no signs of loosening or deformation.
Extended Use & Reliability
Over the past three months, I’ve subjected the Obsidian Arms AR-15 Firing Pin Retaining Pin to significantly more rigorous testing across multiple AR-15 platforms. I have installed the pins in rifles chambered in .223 Wylde and 300 Blackout. These rifles have been used in various scenarios. These scenarios range from casual range days to participating in local 3-gun competitions.
After thousands of rounds fired across these platforms, the Obsidian Arms pins have shown no signs of weakness or failure. Visual inspections after each range session reveal no unusual wear patterns or deformation. The finish remains intact. This level of durability inspires confidence in the reliability of this seemingly simple component.
Maintaining the Obsidian Arms AR-15 Firing Pin Retaining Pin is virtually nonexistent. The pins require no special cleaning or lubrication beyond the routine maintenance of the bolt carrier group. Their robust construction suggests a long lifespan. They have performed significantly better than some of the cheaper, imported pins I’ve used in the past, which tended to bend or break after a few hundred rounds.
