Heritage of the AK-100 Series

The AK-105 is part of the famed AK-100 series—a family of carbines and rifles originally developed in the 1990s as part of the Russian “Century Line of Rifles” for export. Known for their reliability and adaptability, these rifles were numbered 101 to 108 and chambered in various calibers including 5.45×39, 5.56×45, and 7.62×39. Palmetto State Armory’s PSAK-105 pays tribute to this lineage while enhancing it with modern upgrades for today’s shooters.

Precision Engineering

At the heart of the PSA AK-105 is a 4150 steel barrel with a 1:6.5” twist rate, finished in gas nitride for superior corrosion resistance and durability. The pinned and welded spiked booster provides both recoil mitigation and compliance with overall barrel length requirements. A Picatinny railed dust cover allows for direct optics mounting without sacrificing zero retention, giving you flexibility in sighting systems.

Battle-Proven Durability

The PSA AK-105 is built with a stamped steel receiver and hammer-forged front trunnion, bolt, and carrier, all manufactured by Toolcraft to exacting standards. This combination ensures extreme longevity and the ability to handle sustained firing without degradation. The rifle is topped off with a Magpul MOE Grip and Magpul M4 Stock, providing improved ergonomics and comfort over traditional AK furniture.

Modernized Handguard & Controls

The PSA-SLR Rifleworks 11″ SOLO Rail offers a lightweight yet rigid platform with M-LOK attachment points for mounting lights, grips, and other accessories. The ALG AKT Enhanced Trigger with Lightning Bow delivers a crisp, consistent pull, improving accuracy and shot placement. Traditional AK iron sights are retained, including a 90-degree combo sight/gas block and an 800-meter rear sight, ensuring reliable backup aiming capability.
