PSA AK-104 Triangle Side Folding Pistol – 7.62×39 with JL Billet Rail & Picatinny Railed Dust Cover

The PSA AK-104 Triangle Side Folding Pistol in 7.62x39mm with a JL Billet Rail and Picatinny Railed Dust Cover delivers a blend of authentic AK heritage and modern tactical upgrades. Built to the demanding standards of Palmetto State Armory’s 100 Series line, this firearm offers robust construction, enhanced optics mounting capability, and precision-machined components—all backed by PSA’s Full Lifetime Warranty.

Barrel and Muzzle Device

At the core of the AK-104 is a 12.5-inch barrel made from 4150 steel, treated with a gas nitride finish for superior wear resistance and corrosion protection. The 1:10” twist rate ensures stability for a wide variety of 7.62×39 loads. Out front, the Linear Comp Flash Can directs muzzle blast forward, reducing perceived recoil and minimizing side concussion—ideal for confined spaces. The barrel features M24x1.5 RH threading for compatibility with other muzzle devices and suppressors.

Receiver and Core Components

The stamped steel receiver offers classic AK durability while keeping weight manageable. Inside, the hammer-forged 4340AQ front trunnion, bolt, and carrier are precision-crafted for long-lasting performance under the harshest conditions. These components match or exceed military specifications, ensuring the rifle cycles smoothly and reliably over thousands of rounds.

Dust Cover and Optics Mounting

This model features a Picatinny railed dust cover with an integrated rear back-up sight, providing a stable platform for mounting red dots, scopes, or magnifiers. Combined with the side rail optics mount, the AK-104 offers multiple options for configuring your preferred sighting system without sacrificing durability or zero retention.

Handguard and Furniture

The JL Billet upper and lower handguard is CNC-machined from high-quality aluminum, offering exceptional rigidity and heat dissipation while adding modern mounting surfaces for accessories. The Classic AK Grip in black provides familiar ergonomics, while the triangle folding brace enhances stability and can be folded via its internal mechanism for easier storage and transport. (Note: The receiver’s side-folding button only functions with a traditional 4.5mm stock.)

Trigger and Sights

Equipped with the ALG Trigger with Lightning Bow, the AK-104 delivers a crisp, clean break for better shot control and faster follow-up shots. For aiming, it retains the 90-degree combo sight/gas block paired with an 800-meter rear sight, maintaining the AK’s classic sight picture while offering a backup to your optics.
