Palmetto State Armory AK-105 5.45×39 Semi-Automatic Pistol – 12.5" Nitrided Barrel, SLR M-LOK Handguard, ALG Trigger & SBA4 Brace
This U.S-made PSA AK-105 blends the proven AK-74 pattern with modern upgrades, giving you a compact 12.5-inch 5.45×39 pistol that’s ready for customization. A nitrided 4150 steel barrel, free-float SLR Rifleworks SOLO-Lite handguard, ALG AKT-EL trigger, and JMAC/SBA4 brace package set it apart from standard imports while keeping the classic long-stroke gas-piston reliability intact.

The forged 4340AQ front trunnion, bolt, and carrier give this pistol true AK strength. PSA’s hinged dust cover carries a full-length 1913 rail, so optics mount directly over the bore without side rails or specialty bases.
An SLR Rifleworks 9.45-inch SOLO-Lite M-LOK handguard free-floats the barrel and offers plenty of mounting real estate without adding bulk. Its slim profile pairs with the extended knurled charging-handle knob for easy manipulation around accessories.
The trigger group is the ALG Defense AKT-EL lightning bow, delivering a crisp single-stage pull of roughly 3.5 pounds—lighter and cleaner than a stock AK trigger for faster follow-up shots.
At the rear, a JMAC Customs 1913 adapter hosts an SBA4 adjustable brace, giving shooters five length settings and enhanced control while keeping the package short and maneuverable.
PSA’s 12.5-inch nitrided barrel is threaded 24×1.5 mm RH and stabilized with a fast 1:6.5 twist—ideal for the light, high-velocity 5.45×39 cartridge.
