First Impressions of Poly Technologies Hammer Pin Retaining AKS Spring
The Poly Technologies Hammer Pin Retaining AKS Spring might seem like a small, insignificant part, but it’s a crucial component in the AK/AKS platform. Poly Technologies, known for its involvement in the Chinese arms market, provides this essential spring for retaining the hammer pin, ensuring the firearm’s safe and reliable operation. This seemingly simple piece of steel can be the difference between a functional rifle and a frustrating malfunction, making a quality replacement paramount.
What brought me to this particular spring was a nagging concern about the wear and tear on my original AK’s retaining spring after years of use and modifications. The spring is inexpensive insurance for your AK’s reliability and longevity.
My initial impression upon receiving the Poly Technologies Hammer Pin Retaining AKS Spring was its robust construction. The blued steel exhibited a deep, even finish, promising corrosion resistance and long service life. Its small size belies its importance, and a close inspection revealed a tightly wound coil and well-formed loops on each end, inspiring confidence in its ability to perform its intended function.
Compared to generic, unbranded springs, or even some aftermarket options with questionable tempering, this Poly Technologies part felt noticeably more substantial. I chose this specific spring because of Poly Technologies’ established reputation, even if somewhat controversial, in the AK world, and a desire for a part that closely matched the original specifications of my rifle. My initial feeling was one of quiet satisfaction, confident that I had acquired a quality replacement part that would provide years of reliable service.
Real-World Testing: Putting Poly Technologies Hammer Pin Retaining AKS Spring to the Test
First Use Experience
My first opportunity to test the Poly Technologies Hammer Pin Retaining AKS Spring came during a complete teardown and rebuild of my go-to AK variant. I specifically incorporated it during a range session focused on function testing after installing a new trigger group. The environment was relatively clean and dry, typical for an indoor shooting range.
The spring installed smoothly, requiring minimal effort to seat correctly. This immediately indicated proper dimensions and manufacturing tolerances. During the range session, which involved firing several hundred rounds of varying ammunition types, the trigger felt consistent, and there were no failures related to hammer function or pin walk.
Extended Use & Reliability
After several months and approximately 1,500 rounds fired across various range trips and a carbine course, the Poly Technologies Hammer Pin Retaining AKS Spring continues to perform flawlessly. There is no noticeable wear, deformation, or loss of tension. The spring still holds the hammer pin securely in place.
Maintenance has been minimal, consisting of a simple wipe-down with a lightly oiled cloth during routine rifle cleaning. Compared to the previous spring, which showed signs of wear and potential fatigue, this Poly Technologies spring has provided a significant improvement in peace of mind and reliability. I am confident in its long-term durability.
