Add To:

Upper: The KS-47 G2 upper receiver is precision machined out of forged 7075 T6 aluminum, and then hard coat anodized for durability. While retaining the look of a standard M4 upper, the KS-47 G2 upper is designed to work with the new Gen2 KS-47 lower.  The upper features integrated over-insertion tabs to prevent the bolt from dragging on the magazine. This CMV 4150 barrel is chambered in 7.62x39 with a 1 in 10 twist and has a single, large feed ramp to accommodate the larger case diameter of the 7.62x39 round. The barrel 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 AR-15. This Upper is finished with a PSA 7" Lightweight M-Lok Free Float Rail. The KS-47 G2 upper will not work with a standard AR-15 lower.

BCG: The KS-47 Bolt carrier group is designed to work with AK-47 magazines, and features an extended firing pin. The carrier is made of nitride treated 8620 steel, and the gas key is attached with grade 8 bolts and properly staked. The bolt has been redesigned to function properly with most AK-47 magazines. The bolt is nitride treated 9130 steel.

Can you put an 8.5” free float rail same size as the barrel length?
Good206 on May 17, 2019
BEST ANSWER: Absolutely! Many people will put a rail longer than the barrel and tuck a barking spider or similar brake partially under the rail for a clean look
What is the bore diameter of your 7.62x39 barrels?
Grant B on May 16, 2019
can i convert this into a piston instead of DI?
christian s on Jun 14, 2019
BEST ANSWER: Contrary to the Internet Expert’s opinion, Yes it can be and has been converted to use an external piston kit ... and for FAR less than you would pay for a factory piston 7.62x39 AR that still could not use AK magazines. Adams Arms kits specifically have been used successfully, and they only add a couple of extra ounces.

We nicknamed it Thumper...
I was hesitant to get the 8.5 inch barrel... I mated it with a ks-47 pistol lower and a Romeo 5 red dot, and it's awesome... We had one FTE on the second magazine. After that it ran 360 rounds with no issues. We were shooting tula poly coated steel ammo. Big fireball and you feel the concussion from the short barrel and flash hider more than the actual recoil in our opinion.

My teenage kids and small framed wife had no issues shooting it.

Great upper. 100% reliable so far!
I wanted a folding rifle for my boat. I decided on a 7.62 for the short barrel ballistics vs .223/5.56. I built this with a law folder and it's been great!

Runs great
I just got this, put it on a KS47 pistol lower and ran 100 rounds through it of cheap Tula ammo. It ran flawlessly essentially out of the box. I didn't have single misfeed, magazines (Magpul) seated really well, the upper and lower fit together tight. The trigger isn't amazing, but it's fine.

Things I noticed: Recoil isn't punishing, but it's more than you might expect from an AR platform rifle (but makes perfect sense from something tossing 124gr bullets at 2100fps out of a short barrel), it's loud and makes quite a fireball - This isn't a gun you are likely to go shoot 500 rounds through like you might with an 9mm AR.

After reading a number of reviews of this and other attempts at an AR/AK ahem, mutant. I was really impressed by the fact that this just worked at this price point. That said, I will be looking into a better muzzle break at some point. I found the 20 round Magpul magazines to be about the perfect size for a pistol build on this upper.

Great value
Nicely made upper complete with BCG. Will install it and test it on my lower soon. No machine marks, no hiccups & well crafted.
