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 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. 

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 10.5" 4150V chrome moly vanadium barrel is chambered in 7.62x39 with a 1 in 10 twist, has M4-style feedramps, is nitride treated for accuracy and durability, and is finished off with a 5/8-24 thread A2-style compensator, classic carbine length hand-guards and F-marked front sight base.   The forward, assist, dust cover, charging handle, and safety are all standard AR15, as is the classic hand-guards, front sight base, barrel nut and delta ring assembly.

Bolt Carrier Group: Carpenter 158 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.

Will this ever not be “out of stock”?

Will this upper work with a standard AR15 lower?
Hoohhh on May 5, 2018
BEST ANSWER: Yes it pins directly on any standard lower but feeds from a proprietary AR 7.62x39 magazine. Also requires the use of a 7.62x39 bolt and benefits from a titanium or enhanced firing pin for reliable primer ignition using mil surp ammo.
When this kit will be available again? I support PSA FOR YEARS , it's been a year this kits been in stock. Please let me know is ks47 line is be abandon ,I have a lower that can't built.

Fantastic upper
This review is just for the upper - they don't seem to list them alone any more... Anyway like the other reviewer said I was also strongly advised against a 7.62x39 upper but I'm stubborn. This thing runs flawlessly. Using ASC mags and steel case ammo have had zero failure to feed or failure to fire. Being impressively accurate doesn't hurt either. Even sounds better than a 5.56 AR.

Overall a great gun some mag issues though.
I love this pistol build. It works great...and here's the caveat you have to sand some magazines at the feedlips to get it to function properly. Pmags a little FAB defense Ultimags a little less. The Bulgarian 40 round polymer mag did not work and I have to sand that more. I was surprised that East German steel mags did not work and I have to sand them they work in my Mutant. The Bulgy did not work in the Mutant. A Tapco worked in my Mutant not even close with this. I tried it on a AR15 pistol lower with an ASC 10 rounder and it worked perfectly so if you want to build one using a standard AR lower it seems you're good to go. So I have to work on the feed lips of these mags or just use Magpuls and Ultimags.

It's great
I have only used steel cased ammo with asc mags and have not had a problem.

Best Build
No problems what so ever. Fires everytime. I was told i would regret building a 7.62x39. They were wrong. Best build yet!
