First Use Experience

My first experience with the JMac Customs 5.5mm Folding AK Stock Pin was at my local outdoor shooting range. I installed the pin on my KUSA KR-9 and immediately noticed a tighter lockup of the folding stock. The difference was night and day.

Maintenance is straightforward. A quick wipe-down with a lightly oiled cloth after each range session keeps it clean and prevents corrosion. I have experienced no issues with rust or binding.

Compared to the original factory pin, which degraded noticeably after a few months, the JMac Customs 5.5mm Folding AK Stock Pin has proven to be significantly more durable and reliable. This little pin has greatly outperformed the original, and is a must-have upgrade.
