WELCOME TO JMAC’S VAULT! You’ve seen the parts, now see how I run them. We’re launching a brand new Video Blog series where I’m opening up my personal collection to show you the "why" behind every build, every prototype, and every scratch. First up: My Personal AK-105. This isn't a safe queen—it’s a battle-worn machine gun with a warped receiver that has survived years of demo abuse. But even a workhorse needs precision. Finding the perfect optic for your f …

There is a fine line between "modernizing" an AK and ruining its soul. Go too tactical, and you lose that rugged Combloc charm. Stay too purist, and you miss out on the ergonomic advancements of the last 70 years. Today, we are showcasing a brand new AK-105 build that walks that line perfectly. By combining the cutting-edge modularity of JMac Customs engineering with the nostalgic aesthetic of "Rusted Plum" wood, we’ve created a rifle that looks like a Cold War relic but runs like a 21st-c …

The Zastava M77 is a beast of a rifle. Chambered in the hard-hitting .308 Win (7.62x51), it occupies that sweet spot between a standard AK and a full-blown DMR (Designated Marksman Rifle). However, out of the box, the classic Yugo furniture can feel a bit dated for the modern shooter who wants to stretch the rifle's legs. Today, we’re breaking down a dream build that keeps the soul of the Combloc era alive while injecting serious modern performance. By using a suite of JMac Custo …

The Zastava M92 is legendary for a reason. As one of the most robust "krink-style" firearms on the market, it brings the reliability of the Yugo-pattern AK into a compact, hard-hitting package. However, out of the box, the M92 is a diamond in the rough. It lacks modern mounting solutions, optics capability, and ergonomic refinements. That’s where JMac Customs comes in. By stripping the M92 down and rebuilding it with JMac’s ecosystem of modular parts, we can transform this classic f …

There is an eternal debate in the AK community: Wood or Rails? The purists demand Serbian Red wood, claiming that "Rifle is fine." The modernists demand M-LOK, optics retention, and ergonomics. But why choose one when you can master both? Today, we are showcasing a Zastava M70 build that strikes the perfect balance. It retains the soul of the Combloc era through its classic wood accents but upgrades the muscle with a suite of JMac Customs hardware. This is the "Restomod" of the AK world—vi …

Introduction: The Beast Needs a Makeover The Zastava M70 is legendary in the AK community. Known for its bulged trunnion and 1.5mm-thick receiver, the "Yugo" pattern AK is built like a tank. It’s robust, reliable, and undeniably heavy-duty. But "heavy-duty" often comes at the cost of modern ergonomics. The standard wood furniture is iconic, but it lacks M-LOK capability for lights and lasers. The fixed stock has a length of pull that many find awkward, and the recoil, while manageable, ca …

Modernize your Krink with JMAC Customs The Krinkov is one of the most iconic Kalishnikov variants ever designed. From warlords to specialized military personnel, the "Krink" can be seen carried with gusto throughout history. Originally the Krinkov, or AKS-74U, was designed to fire the 5.45x39 round. However, since then, several variants have been made in a variety of calibers including 7.62x39, 5.56x45, and .300 AAC Blackout. What it lacks in barrel length and velocity, it makes up for in reduc …
