The Palmetto State Armory KS-47 is based on the AR-15, and combines the modular construction, accuracy and precision of the AR platform with the stopping power and magazine options of the AK-47.    While the current AR-47 fires the 7.62x39 round, it uses modified AR-style magazines that are not nearly as plentiful as AK-style magazines, which are optimized for reliable feeding of the 7.62x39 round.  The KS-47 lets the AK shooter capitalize on his inventory of magazines and ammo with an AR-style platform.

Unlike the AK-47, 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 KS-47 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 KS-47 hybrid upper is designed to work with either the KS-47 lower, or the standard AR-47 lower.  The 18" 4150V chrome moly vanadium barrel is chambered in 7.62x39 with a 1 in 10" twist, has M4-style feedramps, midlength gas system, 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 15" PSA Lightweight Keymod free float rail.   The forward assist, dust cover, charging handle, and safety selector are all standard AR-15 parts.

Bolt Carrier Group: PSA 7.62x39 Hybrid 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. AR-47 extended length firing pin.

PSA KS47 Classic Lower Build Kit:  PSA KS-47 Classic Pistol lower build kit with 7075 buffer tube, latch plate, A2 Grip, and classic fire control group.  Everything to fully complete your stripped KS-47 lower receiver.

Each upper is test fired to check gas function.

Love this rifle!
I wanted to do a review of this rifle. I have the 16" version of this and it runs flawlessly!!! I've ran all different types of ammo from cheap steel case to expensive hunting rounds! No issues what so ever! I've heard of some people having issues with ftf due to mags rubbing on bolt.... they do not rub as bad as people say! Be rough when you load a round. You can't be all nice and gentle when breaking in mags/bolt. Pull the charging handle back and let go and let the bolt slam the round in! These guns are ment to be used and abused! And once you've ran 90 or so rounds threw each mag your good to go! I shot a doe last year w this round and the knock down power is so much better than .223 you have to purchase this. I'm building this one for my son for deer hunting. The 18" mid length w a muzzle break. And probably have about the same or maybe less recoil than .223 w the break. Can't wait till this is back in stock and I'll be jumping all over it and I can't wait to watch my son drop his first deer too!!!!

Fun project
This was the other half of my blem lower project. Everything went together smooth except for the take down pins. I had to ream the holes with the lower for them to align. Then has to reshape the detents for the pins to round them off a little bit. Then I had to rework the channel of the pins the spot for the detent to sit had a square shoulder so using a dremmel cut a ramp from the slot to the channel and opened up the channel a little bit and reinstalled. Now they are smooth like butter. I wish psa had included their enhanced trigger group over the standard one. The standard one is a little crunchy and stiff. I will either replace with an aftermarket group or try to polish it to relieve some of the creep and reset. All in all I am happy with the project and now considering a pistol variation on this.
