    Jacob Grey Firearms has you covered.

    JG15 Ultralight Complete Upper

    This Ultralight 7.62x39mm 16-inch upper features a JG ultralight M-LOK rail that gives you plenty of real estate to mount said accessories.

    Palmetto State Armory has a knack for finding the sweet spot in the balance between cost and performance, and we can’t help but love the PSA KS-47, a complete rifle built around the 7.62×39 cartridge.

    PSA KS47 with EOTech
    PSA KS-47 with EOTech

    Shooting roughly 2.5 MOA, the KS-47 delivered perfect function and reliability in our testing.

    The KS-47 uses standard AK-47 magazines rather than the steeply curved magazines meant for standard AR-15 lowers. Having a lower that accepts AK magazines helps ensure better feeding and reliability with the 7.62×39 round.

    One perk is that PSA offers the KS-47 in several configurations, including a braced pistol version with a 10.5-inch barrel! The only major downside is the lack of a last-round bolt hold open (thanks a lot, AK mags).

    If you want a complete rifle option, you can’t go wrong with PSA.

    Pros

    • Super affordable
    • Iron sights for the win!
    • Full 16" barrel

    Cons

    • No frills

    If you’re looking for a firearm that’s basic but functional, PSA has you covered with an A2-style upper in 7.62×39.

    The barrel is a 16-inch chrome moly vanadium piece with a 1:10 twist, and topped with a carbine-length gas system and old-school handguard. This thing longs for the jungle.

    The upper is forged 7075-T6 aluminum and then finished with a hard-anodized coating to keep it free of scratches and rust.

    This is the way to go if you’re looking for a basic 7.62×39 upper that is more about function than form. It’s finished well and machined precisely, but it’s pretty plain Jane and doesn’t offer much in the way of customization options by default.

    Pros

    • Piston-drive reliability
    • Quad rail for all the attachments

    Cons

    • Proprietary components

    The Faxon ARAK-21 complete upper receiver comes in a piston flavor instead of the usual direct-impingement.

    This one has a gas adjustment knob so you can tailor the system to whatever kind of ammo you might be shooting. This is extra nice when you’re shooting suppressed.

    Faxon ARAK-21

    It’s built a bit differently than a standard AR-15 upper so some parts aren’t interchangeable, but it does work on a regular lower receiver. That’s the important part.

    It’s a bit heavy with those beefy quad rails, but if you want to go with a piston system like the AK, the ARAK-21 might be for you.

    Author’s 5.56 NATO Radical Upper (BCG and Charging Handle not included.)

    It features a 15-inch M-LOK rail with a full Picatinny top rail for ease of accessory mounting.

    However, this upper doesn’t come with a BCG or charging handle so take that into account when budgeting. You’ll want to get a dedicated 7.62×39 BCG and any standard AR-15 charging handle will do.

    7.62×39 vs. 5.56 NATO: What’s the Difference?

    Simply put, 7.62×39 does things 5.56 NATO can’t (and vice versa). Adding this cartridge to your collection will open up your capabilities — and it’s just plain fun to shoot.

    Popular 7.62x39 Ammo
    Popular 7.62×39 Ammo

    The Cold War-era 7.62×39 is still one of the most popular cartridges around the world. It was designed in the Soviet Union in the latter months of WWII, when the Soviets wanted an intermediate cartridge that could function in a better battle rifle than the bolt-action rifles soldiers had at the time.

    Some of Our Tested AK-47s
    Some of Our Tested AK-47s

    What they got was a solid little round that competed with 5.56 NATO in conflicts around the world for decades.

    Most 7.62×39 bullets weigh 122 to 125 grains, with some 150-grain stuff available if you’re willing to really look for it. That’s a lot more mass than the 55 to 62 grains you usually get from 5.56 NATO.

    Average Muzzle Velocity:~2400fps~3000fps
    Bullet Weight:120-125gr55-77gr

    What Does This All Mean?

    From a practical standpoint, 7.62×39 carries more energy into its target out to about 300 yards. Outside of that, it loses energy rapidly and the heavy round drops quickly.

    The small but speedy 5.56 NATO offers less stopping power at close ranges but it retains energy much more efficiently beyond 300 yards.

    Bottom line:iIf you’re hunting anything up to medium game inside of 300 yards, you’ll want the 7.62×39. If you’re going after smaller game or need to make longer shots, the extra velocity of 5.56 NATO is a better choice.

    FAQs

    How accurate is 7.62x39?

    The Soviets designed the 7.62x39 cartridge to be good enough in close combat, so don't expect sub-MOA accuracy. It's certainly usable out to around 300 yards, though.

    Does 7.62x39 have more kick than 5.56 NATO?

    There are a lot of variables that determine a firearm's recoil but, all things equal, 7.62x39 will recoil harder than 5.56 NATO.

    Will a 7.62x39 upper receiver fit on my AR-15's lower receiver?

    Yes, but you'll likely need magazines designed to work with the AR-15.

    Is 7.62x39 the same as .300 BLK?

    Nope! The two cartridges are pretty similar but they're not interchangeable.

    Final Thoughts

    If you’re interested in 7.62×39 and already have an AR-15, you’ll be pleased to know there are some great uppers out there that will allow you to take advantage of this legendary caliber’s benefits without building a whole new gun.

    Whatever you decide to do, these uppers won’t let you down.

      I spent 2 1/2 years working private security contracts in Iraq. In that time I was issued an AK for some contracts and M4s for others. You use what your employer issues you. Having used both AKs and M4s in a combat environment, I'll take an M4 every time. It has greater precision, reliability, and is much more user-friendly in terms of operation and comfort of carrying one for long hours in a hostile and uncomfortable environment. I'm sure some internet experts will disagree with me, but that's just my opinion based on personal experience.

      Years ago (1990) I obtained a Colt AR upper with a H Bar in 7.62 x 39. Wanting a couple rifles in that caliber, I also grabbed an AK 90 (Norinco w/stamped receiver). The Norinco worked, but that's about all I could say about the cheap knock-off. But I needed a lower for the Colt barreled upper. I grabbed a Bushmaster, then tried and tried to find magazines that would work. I tried converting some Ruger Mini 30's to fit the AR lower with not so good success. But along came ProMag a couple years ago and problem solved. Now, today there's a slew of 7.62 x 39 rifles that make good use of the cheap, surplus ammo (usually about 60% of the cost of 5.56 NATO). The 7.62 x 39 being a heavier and larger round meant, in the Viet Nam days, we could carry more rounds per pound and our 5.56 worked well on the enemy. So the lesser energy wasn't that much of a handicap and the 5.56 was flatter shooting. The availability of surplus 7.62 x 39 ammo after the Soviet Union collapsed made for some pretty cheap shooting even though it was not reloadable... today that's all changed, and there are other rounds that compete with the old Warsaw Pact ammo - such as the 300 black and even the .350 Legend - a straight walled cartridge (I call it the largest 9mm to date) that compares to the old 30-30 ballistically. Now with domestic production of 7.62 x 39 with brass casings, reloading is do-able, and a lot of fun. Considering that the No. 1 cartridge in the world (because of the AK-47) still provides a lot of cheap shooting, it's going to be around a long time.

      You forgot an important one for AR uppers or complete rifles in 7.62x39.
      The PWS MK1 Mod 1 and Mod2. AR upper in 7.62x39 which uses a long stroke piston just like the AK. It shoots flawlessly with C- Products 7.62x39 magazines and runs great with suppressors.

      October 12, 2021 4:58 pm
      • CTT

        Not shocked that PPT left PWS off this list, but I agree wholeheartedly. I own many PWS rifles of all flavors and calibers. Each is equally reliable and incredibly well made. Duramags from Cproducts work perfectly and are easy to find.

        October 13, 2021 10:13 am
      • Danny Warren

        I wholeheartedly agree. I went through 2 other uppers before I got my first PWS MK116 Mod 1 Upper in 7.62x39. I used the Belom 123 gr. Serbian ammo and shot a 10 shot group at 100 yds that could be covered with a quarter. I am a little more than surprised that the PWS Long stroke piston driven AR did not get mentioned.

      "The big advantage it has over the PSA uppers is the piston-drive gas system that runs a heck of a lot cleaner than the direct impingement PSA system."

      This is inaccurate, Radical uppers are DI not piston operated.
      Otherwise mostly helpful info, thank you.

      In my experience, shooting surplus Russian 7.62x39 ammo in a custom-built AR pattern rifle causes a few issues that necessitate a dedicated lower.

      For one, the Russian primers are harder. If you put an aftermarket trigger group in your lower and it has a pull weight of 3lbs, you are bound to find lots of light primer strikes. Stick with a trigger that's at least 5 lbs, or one like delivers a primer strike heavier than the trigger pull, like the Hyperfire. 9mm AR pattern rifles have this same issue.

      Second, depending on the gas tube length and gas block (adjustable vs non-adjustable) on your upper, you may find the buffer weight that works when paired to your .223/5.56 upper does not work as reliably with the 7.62x39 upper. Don't be surprised if you end up buying a different weight buffer later on.

      If you don't buy a complete factory-made AR47 and you decide to build one yourself, it'll require more tuning than an AR15 would, and for this reason it'll be less compatible with the lower you use on your .223/5.56.

      Don't go too long on the gas tube length, 7.62x39 has a lower chamber pressure than .223/5.56. I think the best bet would be to buy an H2 buffer, carbine-length gas system, and especially an adjustable gas block. An adjustable gas block can prevent you from throwing away components and having to buy new ones later, can help to reduce recoil, and can help reduce wear-and-tear from having an overgassed upper. Furthermore, since Russian ammo is dirtier, having less gas blowing back into the receiver is a plus.

      What hell were you thinking when you wrote this? Did you do your research? You didn’t even mention the PWS uppers and complete rifles as an option for 7.62x39 in a reliable, premium AR platform. They are way better than any of the other guns and uppers you just mentioned and their propietary long stoke piston design is the only one that actually operates just like an AK does. You really need to go back and research the PWS 7.62x39 offerings and then amend this article to accurately reflect what AR options chambered in 7.62x39 are readily available to consumers and what’s superior in terms of quality, function, and reliability or else you sacrifice credibility. Kind of hard to take someone serious when they’ve proven their lack of knowledge on a subject they’re attempting to educate others on. No disrespect meant here, I just feel like constructive feedback can lead to improvement.

        Thanks Carl! We definitely love PWS (already reviewed their 16" and I'm finishing up their 7"). Will try to get one of their 7.62x39 uppers in hand.

      I bought a 7.62x39 upper from Pro 2A Tactical. It is a Gibbz Non recipricating, left side charging system, I am running it on a Rock River Arms LAR 47 lower. I just had to do minor releaving to the upper, so I can run the AK mags. I love how it runs, and the rifle manipulation is much more natural, and keeps you on target.
      I plan on buying another of their same uppers, and doing a piston conversion, making what I think, the perfect blend of AK/AR rifle.
      I HIGHLY RECOMMEND CHECKING THEM OUT!
