Real-World Testing: Putting JMac Customs 4.5mm Folding AK Stock Pin to the Test
First Use Experience
I first tested the JMac Customs 4.5mm Folding AK Stock Pin at my local shooting range. I wanted to ensure a proper and secure fit on my Arsenal Sam7SF, as well as smooth operation when folding and unfolding the stock. The weather was clear and dry, ideal conditions for testing out the functionality of this small yet crucial component.
Installation was straightforward, and the pin seated perfectly, offering a significantly smoother action compared to my worn, original pin. The folding mechanism locked up tightly, with no wobble or play. This initial experience gave me confidence in its reliability.
There weren’t any immediate issues or surprises. It worked flawlessly from the start, providing a noticeable improvement in the overall feel and operation of the folding stock. The most immediate thing I noticed was the complete lack of the slight grittiness the original pin had.
Extended Use & Reliability
After several months of regular use, the JMac Customs 4.5mm Folding AK Stock Pin continues to perform flawlessly. It has been exposed to varying conditions, from hot summer days at the range to colder, slightly damp conditions during training exercises. There have been no signs of wear and tear, indicating its high-quality construction.
The black nitride finish has held up remarkably well, showing no signs of corrosion or scratches. Maintenance is simple, requiring only a quick wipe-down with a lightly oiled cloth after each range session. This has proven to be much more reliable than my previous experiences with cheaper pins, which often required more frequent maintenance and lubrication to maintain smooth operation.
Compared to the original pin, which exhibited noticeable wear and a progressively rougher action over time, the JMac Customs pin feels like a significant upgrade. It provides a consistent and reliable performance that I can depend on, outperforming its predecessor in every aspect. Knowing that such a critical function of my go-to AK platform is handled by a quality pin is peace of mind.
Breaking Down the Features of JMac Customs 4.5mm Folding AK Stock Pin
Specifications
The JMac Customs 4.5mm Folding AK Stock Pin is designed specifically for AK platforms utilizing a 4.5mm folding stock trunnion. It is constructed from 4140 heat treated steel, ensuring high strength and durability. The pin features a black nitride finish, providing excellent corrosion resistance.
The key specifications, such as the 4.5mm diameter and the material choice, directly influence the pin’s ability to withstand the stresses of repeated folding and unfolding, as well as exposure to harsh environmental conditions. The 4140 steel provides the necessary strength to prevent bending or breaking, while the nitride finish protects against rust and wear, ensuring a long service life. Without a good quality steel pin, an AK can be effectively neutered.

Its simple design makes it easy to inspect for any signs of damage or wear, and replacement is a straightforward process, should it ever be necessary. The design makes regular cleaning and inspection a breeze, which contributes to its overall longevity and performance.
