PSA AK-104 Triangle Side Folding Pistol – 7.62×39 with SA-19 & SA-10U Handguard and SA-2 Muzzle Brake

The PSA AK-104 Triangle Side Folding Pistol chambered in 7.62x39mm with Soviet Arms SA-19 & SA-10U handguard and SA-2 Muzzle Brake combines classic AK reliability with modern tactical features. This pistol is part of Palmetto State Armory’s 100 Series line, offering rugged construction, advanced ergonomics, and versatility for optics and accessory attachment.

Barrel and Muzzle Device

The AK-104 pistol features a 12.5-inch barrel made of 4150 steel with a gas nitride finish for superior corrosion resistance and durability. Its 1:10” twist rate stabilizes 7.62×39 ammunition for consistent accuracy. The included Soviet Arms SA-2 muzzle brake reduces recoil and muzzle rise, allowing for faster follow-up shots and improved control during rapid fire. The barrel comes threaded M24x1.5 RH for suppressors or additional muzzle devices.

Receiver and Core Components

The stamped steel receiver is lightweight yet durable, while the hammer-forged 4340AQ front trunnion, bolt, and carrier provide military-grade reliability and longevity. These components are engineered for smooth operation and consistent performance in all conditions.

Handguard and Furniture

The AK-104 pistol comes equipped with Soviet Arms SA-19 and SA-10U rails, allowing attachment of lights, lasers, and grips for tactical customization. The Magpul AK grip provides ergonomic comfort, and the triangle folding brace enhances stability and portability. The brace folds internally, while the receiver side folding button works only with a traditional 4.5mm stock.

Trigger and Sights

Featuring the ALG AKT Enhanced Trigger with Lightning Bow, this AK-104 pistol delivers a crisp and clean pull for precise shot placement. The firearm retains traditional AK sights with a 90-degree combo sight/gas block and 800-meter rear sight to maintain classic reliability while offering backup for mounted optics.
