First Impressions of JMac Customs MRKT Trunnion for AKMS Underfolder and Pistols
The JMac Customs MRKT Trunnion for AKMS Underfolder and Pistols promises a solid, non-folding stock/brace mounting solution for AK platforms. As someone deeply involved in the tactical and shooting world for over a decade, I’ve seen my share of AK modifications, some successful, others less so. This trunnion aims to provide a stable, reliable platform for those looking to ditch the underfolder or improve pistol builds, replacing the folding mechanism with a fixed stock or brace mount, something many AK enthusiasts seek for enhanced stability and customization.
For years, I’ve struggled with finding the perfect stock option for my AKMS build. The underfolder, while classic, always felt a bit wobbly and less than ideal for accurate shooting. I was looking for a rock-solid mounting point for a brace that would improve my control and consistency, especially in dynamic shooting scenarios.
Unboxing the JMac Customs MRKT Trunnion, the first thing I noticed was the robust feel of the 4140 heat treated steel. The black hardcoat anodized finish on the 7075 T6 aluminum infinity mount looked clean and durable. Compared to some cheaper trunnion options I’ve seen, the build quality immediately inspired confidence, feeling like a significant upgrade.
I considered the Midwest Industries AK Side Folding Stock Adapter and the Sons of Guns Fixed Stock Adapter, but ultimately chose the JMac Customs MRKT Trunnion because of its direct compatibility with AKMS underfolder rifles and pistols and the reputation JMac Customs has for quality AK parts. The promise of a truly non-folding, extremely rigid mount was simply too appealing. My initial impression was one of excitement, finally feeling like I had found a solution to my AK stock woes.
Real-World Testing: Putting JMac Customs MRKT Trunnion for AKMS Underfolder and Pistols to the Test
First Use Experience
I first tested the JMac Customs MRKT Trunnion at my local shooting range, specifically on my AKMS underfolder build. Installing it was straightforward, taking about an hour with basic tools, and the included mounting bolts provided a secure fit. I used a SBA3 brace with the trunnion to create a stable pistol setup.
The difference in handling was immediately noticeable. The solid, non-folding connection provided significantly improved stability compared to the wobbly underfolder. Even during rapid fire drills, the platform remained rock-solid, enhancing accuracy and control.
Extended Use & Reliability
After several months of regular use, the JMac Customs MRKT Trunnion has proven its durability and reliability. I’ve put several hundred rounds through my AK with the trunnion installed, including drills in dusty conditions and a couple of rainy range days. There are no signs of loosening or shifting.
The hardcoat anodized finish has held up remarkably well, showing no signs of wear despite constant handling and bumping around in my range bag. Cleaning is simple, requiring just a quick wipe down with a lightly oiled cloth. Compared to some of the cheaper stock adapters I’ve used in the past, the JMac Customs MRKT Trunnion is in a different league, offering superior rigidity and longevity.
