PSA AK-104 Side Folding Rifle with Pinned & Welded Spiked Extended Booster and JL Billet Rail – 7.62×39, Black

The PSA AK-104 Side Folding Rifle with JL Billet Rail in 7.62x39mm offers the rugged reliability of the legendary AK platform combined with premium American manufacturing. Featuring a pinned and welded spiked extended Krink brake and a precision-engineered JL Billet handguard, this rifle blends tactical modernization with a traditional design. It is built for shooters who demand accuracy, durability, and adaptability without sacrificing the AK’s renowned toughness.

Barrel and Muzzle Device

The 12.5-inch 4150 steel barrel, extended to 16.2 inches via the permanently attached pinned and welded spiked extended Krink brake, ensures compliance while retaining compact handling. The barrel is finished with a gas nitride treatment for superior wear resistance and corrosion protection. A 1:10” twist rate provides optimal bullet stabilization for 7.62×39, maintaining accuracy at extended distances.

Durable Construction

Built on a stamped steel receiver, the PSA AK-104 utilizes hammer-forged components in the front trunnion, bolt, and carrier. These parts, made from 4340AQ steel, are designed to endure high round counts under demanding conditions. This is a rifle built for longevity and dependable performance in any environment.

JL Billet Rail System

The addition of the JL Billet rail elevates this AK-104’s capabilities. Machined from high-quality aluminum, the rail offers M-LOK compatibility for accessories such as foregrips, lights, and lasers. Its precision fit ensures solid mounting without compromising barrel harmonics, allowing for both tactical customization and consistent accuracy.

Furniture and Ergonomics

The rifle features a classic polymer AK-47 side folding stock for compact transport and storage, measuring 25.5 inches folded and 34.75 inches extended. The black classic AK grip provides a familiar, comfortable hold for traditional AK shooters while accommodating modern shooting techniques. The folding stock enhances portability without sacrificing stability during firing.

Enhanced Sighting Options

Equipped with a 90° combo sight/gas block and an 800-meter adjustable rear sight, the AK-104 offers traditional sighting options out of the box. A side rail optics mount is also included, giving shooters the flexibility to install red dot sights, prism scopes, or magnified optics to match their mission profile.
