Add To:

The Palmetto State Armory KS47 is based on the AR15, and combines the modular construction, accuracy and precision of the AR platform with the stopping power and the magazine options of the AK.    While the current AR47 fires the 7.62x39 AK round, it uses modified AR-style magazines that are not nearly as plentiful as AK-style magazines, that were optomized for reliable feeding of the 7.62x39 round.  The KS47 lets the AK shooter capitalize on his inventory of magazines and ammo with an AR-style platform.

Unlike the AK, where the barrel is permanently pressed into the receiver, the KS47 features an AR-style modular configuration which consists of a barreled upper receiver, and a lower receiver that houses the fire control group and magazine.  The modular configuration allows customers to have several different barrel configurations with one lower receiver, just by releasing two pins. 

Upper:  The KS47 hybrid upper receiver is precision machined out of billet 7075 T6 aluminum, and then hardcoat anodized for durability.   While retaining the look of a standard M4 upper, the KS47 hybrid upper is designed to work with either the KS47 lower, or the standard AR47 lower.  The 7.5" 4150V chrome moly vanadium barrel is chambered in 7.62x39 with a 1 in 10 twist, has M4-style feedramps, pistol gas system, and is nitride treated for accuracy and durability, and is finished off with a 5/8-24 thread A2-style compensator, low profile gas block and 6" PSA Lightweight Keymod free float rail.   The forward, assist, dust cover, charging handle, and safety are all standard AR15.

Bolt Carrier Group: 9310 Phosphate coated 7.62x39 bolt, Full auto profile 8620 steel carrier, chrome-lined and phosphate coated. Phosphate coated chrome-lined gas key staked per mil-spec. AR47 extended length firing pin.

PSA KS47 Classic Pistol Lower Build Kit:  PSA KS47 Classic Pistol lower build kit with 7075 pistol tube. double loop latch plate, A2 Grip and classic fire control group.  Everything to fully complete your stripped KS47 lower receiver.

Each upper is test fired to check gas function.
