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.

Great Rifle with limitations
I am writing this review based off of my own build. I used the KS47 upper lower and BCG. All other parts I bought from other sources. It has the issues that others have reported the mag over insertion. If the mag is touched or you rest the rifle on it while it is cycling the bolt will hang on the magazine. I am hoping they will create a solution for this at some point. It does shave some of the feed lips off of your polymer magazines initially during break in. I have found with my rifle that every magazine I have tried will lock in however; it will not reliably cycle on any of my steel magazines. This is somewhat disappointing since there are a ton of cheap surplus steel mags out there. I am have considered dremeling some of the metal mags a little to see if it helps. Overall I do really like this rifle and I would purchase again. I fired 300 rounds on my first range trip with this rifle. There were no light primer strikes and the rifle performed well aside from the issues I mentioned above.

This is well worth the money
I've had the rifle for a few months now. I outfitted mine with a primary arms 1-6 accs optic. It has full field my hopes of a great shooting 7.62 by 39. I have recommended friends and family to shoot and enjoy and maybe get one of their own. Thank you Palmetto for an excellent rifle at a working mans budget

So far so good on initial test
Didn't buy the rifle I purchased the stripped upper/lower/bcg to build my own and thought I'd write a review to report my initial test of the bcg getting hung up on the pmags which according to many of the online reviewers of the KS47 is the primary cause for the constant FTF/FTE issues until the bolt lugs wear down a groove in the feed lips. I purchased the PSA KS47 stripped upper/lower and the bcg (once it was in stock). I was prepared to take a dremmel to a couple of pmags to grind down the feed lips just a little to give the bolt lugs enough clearance to prevent friction slowing down the bolt cycle. Two youtubers' used this method with success. Surprisingly with no modifications to the magazine the bcg dry cycled with no hang ups on the feed lips. I then loaded up some 'snap-caps'(dummy rounds)and the bcg cycled freely with no FTF's/FTE's. Now if you put pressure on the magazine in my case rearward pressure on the mag the bcg will hang up during the cycle. This is not a problem for me since I don't shoot while gripping the mag but I wanted to test this out since others had complained about malfunctions while using this shooting style or shooting prone with the mag contacting the ground or bench causing forward or rearward pressure on the mag. I must note that in my case forward pressure on the mag did not cause any malfunctions with the 'snap caps'. Will update again once I get to the range with live rounds but I suspect this thing will run nicely. Not sure if PSA has done any modifications to the bcg since introduction but the one I have appears to work fine with the pmag....the polymer Tapco mag however is a different story. The tapco mag does not fit well into the ks47 lower at all. I remember reading that the ks47 was designed to work with the pmags so I figured the similar looking tapco polymer mag would work. Pmags only I guess.

800 rounds later...
There was very little reviews of this rifle on YouTube other than the sales pitch reviews. I love the concept of an AR - AK47 hybrid. I saw a handful of makers of this kind of variant on the AR platform. They were over $1300. So on price I rated it 5.

For the value I gave it a 5 also because I use the other $400 I have to spend on the bling - Troy sights Strike Industries handrail covers enhanced trigger set VG6 muzzle brake Magpul pistol grip MFT stock H2 buffer longer buffer spring. With this rifle being an AR lower it's easy to find parts for it.

Quality- is where is have to knock a star. Upon ordering this rifle and knowing it's on its way I initially grabbed a couple of Korean AK steel mags. This is when I started having problems. The bolt lugs were binding with the feed lips of the steel mags. I noticed out was about 1-2 mm so I just filed it down. This fixed that problem. I was using Russian made TulAmmo so I was also experiencing FTF once or twice per magazine. I then used the H2 buffer and replaced the buffer spring with a longer and more tension to push that steel casing round into the chamber. With these changes my 2nd trip to the range I've had no issues. I shot another 200 rounds per trip to the range. After my 4th trip 800 rounds later the issues of FTF and FTE aware no more. I'm loving this rifle more and more.

Overall it's an awesome gun. I use a 3" pink Post-It note on the paper target and I can put all 25 rounds / magazine into that little Post-It note paper at 25 yards away with iron sights. The VG6 muzzle brake keeps me on target. The Strike Industries rail covers keeps your hands from burning.

Love it!
Picked up a blem KS47 stripped lower on one of PSA's weekend sales along with the KS47 keymod upper and LPK. Got the upper and LPK shipped to the house withing a couple of days of ordering and picked up the blem stripped lower the following Saturday. Assembled everything that Saturday afternoon while watching Georgia lose to Florida... again. :(

Got invited to go out shooting with a friend at his gun club that has a 500m steel range. I was in a rush that afternoon to find some sights as I didn't have any spares at home. Picked up some DD BUIS and then when I got home remembered I still had an Bushnell TRS-25 that took off my S&W M&P in favor of a Vortex AR1X.

Anywho got to the range Sunday morning and sighted the rifle at 25 then 50yards. At 50 yards with the 3MOA reddot was able to blow out the X ring with this rifle. We then moved up to the 500m steel range and that's when the rifle shined. 200m 12" plate I was ringing it 25 out of 30 rounds. With some spotting help was able to reach out to 500m and hit a 24x24" plate a handful of times.

Just put in a Geissele G2S trigger that I got on sale from DPMS last night with no problems.

As others have noted some magazines don't like to feed the first round for some reason. Either loosening the mag a little for that first round or using the foward assist seems to help. I only put about 150 rounds through it so we'll see how it loosens up over time.

All in all I freaking LOVE this rifle. Gonna pick up a Primary Arms 1x6 7.62/300blk ACSS scope for this as well and probably a bi-pod. Hope to be able to MOA groups with this.

My buddy I went to the range with is now considering buying one of these as well.

Quality Control issue
Let me start by saying that I have purchased numerous uppers and lowers from PSA without incident before. Quality uppers and great prices. The ks47 is very lightweight and decent price point. However rcvd my rifle today and out of the box the bcg gets hung up on the lips of the included ak pmag. Going to test fire tomorrow to see if maybe it just needs breaking in but not confident as it will defenitely slow the carrier down. I waited for about a month for it I hope I don't have to try out PSA's customer service and return the rifle for repair.

Edit by PSA: the polymer magazines may need 25-50 rounds to get seated properly.

Great shooter
I purchased and shot this gun today putting about 250 rounds thru it. Chose it because I wanted something different than just a normal ar15. Great finish and quality. 2 issues I've had today however. The pin that holds the magazine in place toward the front of the mag well walked out and somehow fell out of the gun after I was done shooting. Hoping PSA gets back to me soon for a new one that won't back out! Also tapco usa p mags will not work with this gun they fit too tightly in the gun and will not feed for some reason. Had no issues with Polish surplus mags or the magpull mag that came with the gun. Great unique gun for the price other than that.

Best of all worlds
Me and my wife were looking for a ar style gun for a while we have a few stipulations tho affordable not much we'd need to upgrade light Weight and easy on my wife's shoulder. We looked at AR15sfor about a year and just couldn't find anything we both agreed on. Than we started looking at AR10 and same thing she didn't like any of them. We went out with a friend who had a ak47 and I immediately started looking at aks but I still Leland two rd the ar style look. This gun has meet all our standerds it looks great has great parts is light and super easy kick. I researched it for a few weeks and both of us finally agreed. Out first time shooting it we sighted it in at 150 yd and shooting at a 6in target dangling from a chain hut it every time and in a fairly good grouping for a swinging target. I put a scope and a slanted grip on it and that's all it's the best gun we have by far stoping power of a 7.62 with the accuracy of a 223! Love this gun. I had to buy it from a gun store because it was never in stock on psa. Only problem we've had is some ak mags ar to fat to fit in.

Love it!
I received this rifle Friday from my FFL. I added a Vortex StrikeFire II the took it to the range. I ran 500 rounds through it with very few issues. First of all the accuracy reviews are correct. This thing out performs all of my AK's. It ran every thing I put in it and I was surprised at how well it ran Wolf Soft Point. The bolt did hang up on a few mags but it wasnt really a failure to feed as I could use the forward assist to get it into battery. I think If I find the mags it likes I'll just stick to running them with it. The biggest issue was the pin that holds the lip of the AK mag walked out. There is a set screw on the top of the lower that was loose. I ended up marking the pin and cutting a tiny divot with a dremel then seating the seat screw in the divot to make sure this pin never walks. I did use red loctite to keep it in place. Last thing is that the handguard heats up fast! The handguard is very close to the barrel so the heat transfers easily. Wear gloves and have fun!

never seen an ak this accurate
I lubed this up a bit put an Aimpoint PRO on and went to my local indoor range to sight in at 15 yds. After getting the optic aligned properly I put the last 10 rounds pretty much through the same hole. I am thoroughly impressed with this firearm. The buttstock isn't super comfortable but I appreciate the design and it sure is light. I only had time to put 60 rounds through but had zero feeding issues. I filled the included plastic mag with Yugoslavian military surplus brass and then used an old metal AK mag with some steel cased junk I've had for 20 years. Again zero feeding issues. Can't wait for some long range outdoor time ...
