PSA AK-104 Triangle Side Folder Pistol – 7.62×39 with SA 11.5″ Booster Cut Rail, Railed Gas Tube, Picatinny Dust Cover, and JMAC M24 RRD360 & Blast Shield

The PSA AK-104 Triangle Side Folder Pistol is a modern, American-made take on the legendary short-barrel AK platform. Chambered in 7.62x39mm, this pistol configuration offers exceptional maneuverability, robust construction, and premium upgrades for the discerning shooter. Outfitted with a Soviet Arms 11.5″ booster cut rail, railed gas tube, picatinny railed dust cover, and a JMAC M24 RRD360 muzzle brake with blast shield, this AK-104 is designed for both performance and adaptability in the field.

Barrel and Muzzle Device

The 12.5-inch 4150 steel barrel is finished in gas nitride for superior wear resistance and corrosion protection. Its 1:10” twist rate ensures optimal stabilization for 7.62×39 projectiles. At the muzzle, the JMAC 360 M24-1.5 Face Keymount brake works in tandem with the JMAC Brave extended blast shield to control recoil, direct blast forward, and reduce muzzle rise—ideal for close-quarters shooting or range work. The M24x1.5 RH threading allows for straightforward attachment of compatible muzzle devices and suppressor mounts.

Receiver and Core Components

Constructed from stamped steel, the receiver is paired with a hammer-forged 4340AQ front trunnion, bolt, and carrier. These forged components are built to endure decades of sustained firing, giving you battlefield-proven durability in a modern package. The pistol also comes equipped with a hinged dust cover for faster maintenance and consistent optics zero retention.

Premium Furniture and Rails

The Soviet Arms 11.5″ booster cut rail and Soviet Arms railed gas tube provide multiple M-LOK and Picatinny mounting points for lights, grips, and lasers. A Magpul MOE AK grip in black delivers ergonomic comfort and improved weapon handling, while the triangle side folding brace with JMAC RSA 4.5 Picatinny adapter offers compact storage and stability during fire. Note: the triangle brace folds using its own internal mechanism; the receiver’s side-fold button only functions with a traditional 4.5mm stock installed.

Trigger and Controls

This AK-104 pistol is fitted with an ALG Defense trigger with Lightning Bow, offering a cleaner, shorter, and crisper trigger pull than standard AK triggers. The rear peep sight paired with the 90° combo sight/gas block ensures precise aiming and a traditional AK sight picture.

Historical Influence Meets Modern Innovation

The AK-104’s design lineage traces back to the Russian “Century Line of Rifles” from the 1990s, developed for export during a time of economic strain. Palmetto State Armory honors this heritage while introducing modern upgrades in materials, machining, and ergonomics. This combination of old-world reliability and modern innovation makes the PSA AK-104 pistol a standout choice for collectors and tactical shooters alike.

Compliance and Conversion Potential

This pistol configuration provides AK purists with the authentic short-barreled rifle (SBR) experience without requiring an immediate NFA registration. Upon ATF tax stamp approval, users can easily convert this pistol into a folding-stock rifle by swapping the brace for a traditional stock via a quick pin-and-adapter removal process.
