First Impressions of JMac Customs SS-9RP Stock 5.5mm Folding Aks w/Rubber Butt Pad
The JMac Customs SS-9RP Stock 5.5mm Folding Aks w/Rubber Butt Pad promises to be a game-changer for AK enthusiasts looking to modernize their rifle with a folding stock while maintaining compatibility with the robust Russian 5.5mm pin system. I’ve been modifying and building AK platforms for over a decade, and I’ve consistently sought improvements in ergonomics and portability without sacrificing the core reliability of the AK. The lure of this stock is its ability to enhance a rifle’s packability and maneuverability, particularly in confined spaces, a critical factor for many tactical and recreational scenarios.
What led me to this product was a persistent need to reduce the overall length of my AK when stowed, especially during transport in vehicles or when navigating dense brush. My existing fixed stock AK was cumbersome, and I found myself constantly wishing for a more compact solution. Opening the box, the JMac Customs stock made an immediate statement with its clean lines and robust construction. The 7075 T6 Aluminum felt incredibly solid, and the Hard-Coat Anodized finish exuded quality, suggesting this wasn’t just a cosmetic upgrade but a serious piece of hardware.
I considered several other folding stock options, including stocks requiring trunnion modifications, and some of the cheaper polymer offerings. I ultimately chose the JMac Customs SS-9RP because it claimed to directly interface with the existing 5.5mm trunnion, eliminating the need for potentially damaging gunsmithing work. My initial impression was one of cautious optimism; if it performed as advertised, it would be an ideal solution.
Real-World Testing: Putting JMac Customs SS-9RP Stock 5.5mm Folding Aks w/Rubber Butt Pad to the Test
First Use Experience
My first field test took place at a local shooting range during a training session focused on dynamic movement and weapon transitions. I mounted the JMac Customs SS-9RP Stock on my SGL-31, a rifle known for its reliability but also its somewhat dated ergonomics. The conditions were dry and sunny, perfect for assessing the stock’s performance in a controlled environment.
Installation was straightforward, slotting into the existing 5.5mm trunnion with minimal fuss. The folding mechanism operated smoothly and locked securely in both the open and folded positions. Initially, the 0.275in Cheek Rise felt slightly different than my previous stock, but after a few adjustments, I found a comfortable cheek weld. After the first few magazines I began to appreciate the integrated QD sling socket which made transitions much smoother when combined with my two-point sling.
Extended Use & Reliability
After several months of regular use, including multiple range trips and a backcountry camping excursion, the JMac Customs SS-9RP Stock has proven to be a reliable and worthwhile upgrade. There are no signs of loosening or play in the folding mechanism and the finish still looks like new. The rubber buttpad shows minimal wear, even after being repeatedly deployed in various terrain.
Maintenance is a breeze; I simply wipe down the stock with a lightly oiled cloth after each range session. The durable anodized finish resists scratches and corrosion exceptionally well. The stock significantly outperforms my previous setup regarding portability and ease of handling, particularly in confined spaces like the interior of a vehicle.
