Let’s Talk About KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins
The KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins are small components that make a big difference in the performance and longevity of an AR-platform rifle. Manufactured by KNS Precision, these pins are designed to prevent the trigger and hammer pins from rotating within the receiver. This seemingly minor upgrade addresses a potential point of wear and tear, contributing to a smoother, more reliable trigger pull and extending the life of critical fire control components.
I’ve spent years observing how small parts, often overlooked, can cause significant malfunctions in the field. Regular trigger pins can walk out, especially under the stress of rapid firing or in harsh conditions, so I sought a solution to mitigate this risk. My initial assessment of the KNS Precision pins was positive. They appeared robust, well-machined, and ready to handle the rigors of hard use.
Compared to standard mil-spec pins and some of the cheaper anti-walk pin sets on the market, the KNS Precision pins stood out for their build quality. I chose these pins over alternatives because of KNS Precision’s reputation for producing high-quality, durable components. The non-rotating design and enhanced diameter appealed to my desire for increased reliability and a more consistent trigger feel.
I was immediately impressed by the apparent quality and thoughtful design. The slightly larger diameter suggested a tighter fit, and the anti-rotation feature promised to address a common issue with AR-15 trigger groups. This upgrade held the promise of enhanced reliability and longevity for my AR-15, something that genuinely excited me.
Real-World Testing: Putting KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins to the Test
First Use Experience
I installed the KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins on my primary AR-15, which sees regular use at the range and in force-on-force training scenarios. Testing took place primarily at an outdoor range, across various weather conditions, from dry and dusty to light rain. Installation was straightforward, requiring only a punch and hammer.
The initial range session revealed an immediate improvement in the feel of the trigger. There was noticeably less “slop” in the trigger and hammer, resulting in a crisper, more consistent pull. The rifle performed flawlessly through several hundred rounds, and the pins remained securely in place without any sign of rotation.
Extended Use & Reliability
After several months of consistent use, the KNS Precision pins continue to perform admirably. The pins show no signs of wear or deformation, despite regular cleaning and maintenance. The trigger pull remains consistent, and the peace of mind knowing the pins are secured is invaluable during high-stress training scenarios.
These pins have proven to be highly durable. I’ve put thousands of rounds through the rifle since installing them, and they still look and function as new. Cleaning is simple, requiring just a quick wipe with a cloth and a light application of oil.
In contrast to my experience with standard pins that would occasionally walk out after extended use, the KNS Precision pins have exceeded my expectations. They have provided a noticeable increase in reliability and consistency, making them a worthwhile upgrade.
Breaking Down the Features of KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins
Specifications
The KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins boast several key specifications. The manufacturer is, of course, KNS Precision. The pins are constructed from pre-hardened 4140 steel, a material known for its strength and durability.
These pins feature a .1550 diameter, slightly larger than standard pins, ensuring a tighter, more secure fit within the receiver. They are part of the Gen G series, indicating design refinements and improvements over previous generations. These pins are specifically designed for use in M16, M4, and AR-15 rifles.
These specifications are crucial for several reasons. The 4140 steel construction ensures the pins can withstand the high stresses associated with repeated firing. The slightly larger .1550 diameter minimizes play within the trigger group, contributing to a more consistent trigger pull and preventing pin walk.
Performance & Functionality
The KNS Precision AR15/M16 .1550 Diameter Gen G Non-Rotate Trigger/Hammer Pins excel at their primary function: preventing trigger and hammer pin rotation. This enhances trigger feel and prevents potential malfunctions caused by pin walk. They offer a noticeable improvement in trigger consistency and overall reliability.
The strengths of these pins lie in their simple yet effective design and robust construction. The only potential weakness is that the slightly larger diameter may require minor fitting in some receivers, though this has not been my experience. They meet and exceed my expectations for a drop-in trigger pin upgrade.
Design & Ergonomics
The KNS Precision pins feature a straightforward, functional design. They are precisely machined from steel and finished with a durable coating. The slightly increased diameter ensures a snug fit, and the non-rotating design eliminates the need for external retaining clips or screws.
The installation is simple, and the increased rigidity of the trigger group contributes to a more solid feel. There is no learning curve associated with their use. The slightly larger diameter might require a bit more force during installation, but the improved performance is well worth it.
Durability & Maintenance
The KNS Precision pins are built to last. Constructed from hardened steel, they are highly resistant to wear and tear. Regular cleaning and lubrication of the trigger group will further extend their lifespan.
Maintenance is minimal. Simply clean the pins along with the rest of the trigger group during routine firearm maintenance. The durable finish resists corrosion, ensuring long-term reliability.
