PSA AK-104 Triangle Side Folding Pistol – 7.62×39 with PSA-SLR SOLO 9.45″ Lite MLOK Rail and Linear Comp

The PSA AK-104 Triangle Side Folding Pistol in 7.62×39 combines the reliability of the classic AK platform with modern tactical upgrades. Featuring the PSA-SLR SOLO 9.45″ Lite MLOK Rail with Railed Gas Tube, a Linear Comp Flash Can, and the ALG AKT Enhanced Trigger with Lightning Bow, this pistol is engineered for performance, precision, and versatility.

Barrel and Muzzle

This AK-104 pistol features a 12.5″ barrel made from durable 4150 steel with a gas nitride finish for superior corrosion resistance. Its 1:10” twist rate ensures consistent accuracy with standard 7.62×39 ammunition. The Linear Comp Flash Can helps reduce muzzle rise, improving control and rapid follow-up shots. Barrel threading is M24x1.5 RH for optional muzzle device attachments.

Receiver and Core Components

Built with a robust stamped steel receiver and hammer-forged 4340AQ front trunnion, bolt, and carrier, this AK-104 ensures durability, reliability, and smooth cycling under rigorous use.

Handguard, Grip, and Brace

Equipped with the SLR Rifleworks AK SOLO 9.45″ Lite MLOK Rail with Railed Gas Tube, this pistol allows mounting of optics, lights, and other tactical accessories. The classic AK grip ensures comfortable handling, while the Triangle folding brace provides stability and compact portability. The brace folds internally, and the side folding button only functions when using a traditional 4.5mm stock.

Trigger and Sights

The ALG AKT Enhanced Trigger with Lightning Bow delivers a crisp, precise trigger pull for improved accuracy. Backup sights include a 90-degree combo sight/gas block and a rear peep sight for reliable aiming without optics.
