PSA AK-104 Side Folding Rifle with Pinned & Welded Spiked Extended Booster – 7.62×39, Plum

The PSA AK-104 Side Folding Rifle in Plum delivers the proven durability of the AK platform with modern American craftsmanship. Chambered in 7.62x39mm, this rifle combines the compact maneuverability of a short-barrel configuration with the compliance of a pinned and welded spiked extended Krink brake. Its classic plum-colored furniture evokes the heritage of late Cold War AKs, making it equally appealing to collectors, enthusiasts, and practical shooters.

Barrel and Muzzle Device

The 12.5-inch barrel, crafted from 4150 steel, is permanently extended to 16.2 inches with the pinned and welded spiked extended Krink brake. This not only ensures legal compliance but also provides effective recoil and muzzle rise mitigation. The gas nitride finish increases surface hardness and corrosion resistance, making the barrel ready for heavy use. A 1:10” twist rate is optimized for the 7.62×39 cartridge, ensuring consistent accuracy across a range of bullet weights.

Rugged Construction

Built around a stamped steel receiver, this AK-104 uses hammer-forged 4340AQ steel for its front trunnion, bolt, and carrier—critical components engineered for extreme durability. These manufacturing choices extend the rifle’s operational life, even under continuous firing conditions. The result is a firearm that can withstand decades of regular use.

Classic Plum Furniture

The AK-104 in this configuration sports plum-colored classic upper and lower handguards, a plum classic AK grip, and a plum polymer side folding stock. This distinctive color scheme pays homage to the Soviet and Russian rifles of the late 1980s and 1990s. The side folding stock allows for a compact folded length of 25.5 inches, making transport and storage easier without sacrificing stability when extended to its full 34.75-inch length.

Sighting and Optics Options

The rifle features a 90° combo sight/gas block and an 800-meter adjustable rear sight, delivering proven AK sighting reliability. It also comes with a side rail optics mount, enabling shooters to easily attach red dot optics, prism scopes, or magnified optics for enhanced target acquisition in both short- and long-range scenarios.
