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 optimized 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.
Lower: The 7075-T6 billet lower receiver is hardcoat anodized, and accepts standard AR15 fire control groups. The extended magazine release is outside of the trigger guard for safety, which allows for an AK-style release movement, but also features oversize side paddles for fingertip release by the trigger finger. Fitted with a standard PSA A2-style grip and M4-style stock, the receiver also features a standard, mil-spec diameter, 6-position 7075 carbine buffer tube. The KS47 lower has steel reinforcements to accept AK style surplus magazines including drum-style.
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 chrome moly vanadium barrel is chambered in 7.62x39 with a 1 in 10 twist, has M4-style feed ramps, is nitride treated for accuracy and durability, and is finished off with a 5/8-24 thread A2-style compensator. The forward, assist, dust cover, charging handle, and safety are all standard AR15, as is the PSA Slim Keymod free-float rail and barrel nut.
BCG: The hybrid KS47 Bolt carrier group works with either AK47 magazines or AR47 magazines, and features an extended firing pin. The carrier is made of 8620 steel, chrome lined and phosphate coated, and the chrome lined gas key is attached with grade 8 bolts and properly staked. The Bolt is made of phosphate coated 9310 steel.
The KS47 Upper and Hybrid BCG are compatible with standard AR15 lowers for use with AR47-style magazines.
