The Great Debates: AR-15 vs. AK-47

By CTD Blogger published on in Firearms

It is an argument that has been around for decades. Which is the better rifle platform, Eugene Stoner’s AR-15/M16 or Mikhail Kalishnikov’s AK-47? Police and military forces around the world use both extensively, and the two platforms have been head-to-head against each other in various military conflicts for nearly 50 years. Still, each seems to shine in its own particular way.

Caliber aside, probably the biggest difference between the two rifles is the built-in tolerances. Manufacturers built the AK-47 to function flawlessly in any condition. And makers built the AR-15 to be incredibly accurate as well as reliable, but the finer tolerances increase the chance for failure. It is also extremely lightweight, with most parts made from high-strength aluminum with a few critical steel components. On the other hand, the AK-47 is almost all steel, making it that much more durable but also significantly heavier.

Iron sights on the AR platform are much better than the AK, with a rear aperture sight and front blade. The AK, by comparison, has only a rudimentary Partridge sight system. Scopes are more difficult to mount on the AK, requiring a forward scout-style mount, a difficult-to-stabilize receiver cover or side-rail mount. AR rifles, by comparison, were designed to have optics securely mounted on the integrated carry handle or attached to the Picatinny rail on later flat-top models.

Each rifle has certain performance requirements. The U.S. military wanted a precision rifle that was lightweight, very accurate and could fire a high-pressure, lightweight projectile. The Soviet Union, on the other hand, wanted a tough and nearly indestructible rifle that performs well under the harshest conditions. Both got what they wanted.

Below, we evaluate the two on a number of parameters, evaluating weight, ballistic performance, ergonomics, and price.

AK-47 AR-15/M16 Superior Rifle
Maximum Effective Range 400 yards 600 yards AR-15/M16
Weight (empty) 9.5 pounds 7.8 pounds AR-15/M16
Weight (loaded, 30 round magazine) 10.9 pounds 8.8 pounds AR-15/M16
Muzzle Energy 1,500 foot-pounds 1,300 foot-pounds AK-47
Energy at 400 yards 462 foot-pounds 536 foot-pounds AR-15/M16
(16″ barrel)
8-12 MOA 6-8 MOA AR-15/M16
Reliability Functions under nearly any condition Prone to failure when exposed to dirt, dust, and mud AK-47
Ergonomics Safety/selector switch is a bit awkward requiring the user to break grip on the rifle; cheek weld is virtually non-existent Excellent cheek weld; safety/selector switch is manipulated easily without losing sight picture AR-15/M16
Recoil Noticeable but easily managed in semi-automatic Easily controllable, even under rapid fire AR-15/M16

Just looking at the side-by-side comparison, one has to give the nod to the AR-15/M16. It is more accurate and offers superior ballistics at long range. The AK-47 is clearly superior for reliability and short-range ballistics, making it an obvious choice for anyone who needs a short-range tactical rifle. Its traits clearly make it the better choice for close-quarters urban or jungle fighting in which engagements will usually be fewer than 100 yards.

Those ballistic differences disappear when you compare the AK-74, instead of the AK-47, to the AR-15. The AK-74 fires a 5.45x39mm cartridge with similar performance to the NATO 5.56mm standard round. The AR still wins on accuracy, but the ballistics are the same out to 600 yards. What does that mean? Although the effects of a hit on a target at long range are about the same, with the AR-15 you are more likely to actually hit your target at 600 yards than with the AK-74. That primarily is due to differences in bolt design and barrel attachment.

Still, at the end of the day, the customer staring at both rifles has to make a decision. Do you go with fool-proof reliability at a lower cost and choose the AK, or drop the extra cash on the AR-15 (what many call “the Lego System of weapons”) and have an accurate, modular system  you can adapt to multiple roles and calibers? If you are like me, you will spend even more and get one of each. Which one you choose ultimately will depend on the role you want it to play. Need the ultimate in reliability and close-range support? Get the AK. More interested in an easily modified modular system that boasts excellent long-range accuracy and ballistics? Get the AR.

    The designer of the AK was “Kalashnikov”, not “Kalishnikov”.

    4-8 MOA on an AR15? My PSA budget build shoots MOA (1.22 average of five 3 shot groups with 2 sub MOA at 100 yards) out of the box. Any rifle at 4 MOA is unacceptable.

    I have both ARs and AKs and while I enjoy shooting both I’ve found that the AKs are MUCH more reliable and much less choosy about the ammo they’re fed.

    I’m a few years late, but holy crap CTD really took a dump with this article.

    Unloaded AKs weigh 9.5 pounds empty? Sure, maybe the original 1940s AK47. Modern AKs? 7.5 lbs empty.

    Cheek weld is NOT “virtually non-existent” on an AK, unless you are using an underfolding stock (which is not what the pictures shows).

    Also, modern AKs as well as ARs have about the same off-the-rack MOA at around 4MOA, unless you’re buying an expensive model and using match ammo. Certainly not the 8-12 MOA that CTD is suggesting.

    A perfect example of an article written by an employee who dug up random internet facts by skimming Wikipedia, who obviously never owned or shot either rifle.

    I prefer the AR it is AMERICAN, The AK is an ok 100-200 yd gun but beyond that it is not very accurate. If you use the AR-15 with hollow points at up to 400+ yds it will be very effective. I prefer the AR design in a 308 which will out perform the AR15 and the AK for accuracy and penetration
    The AK is better than nothing but when it comes to protecting your life don’t go cheap, In a SHTF scenario you will find more ammo and parts for the AR 15 its AMERICAN


  • Glen Mack


    I have a “Saga” some say it’s one of the best others say it’s O.K. but I could have done better. It seam’s to be very accurate, and very reliable. I all so find that it will shoot good amo, as well as junk, where as the AR-15 for the most part shoots premo, or upper grade. I guess my question is did I make the right choice in your opinion?

    My custom built ar (im an amateur, built it using youtube,lol), has never had a missfire,ftf,or fte after 2000+ rounds. I bought a cheap lower, a dpms lower parts kit, a dsa and rguns upper (16in dsa 20in bull barrel rguns), and i have never had one problem. I have not owned an ak, but i had an sks. Stupid gas tube release came loose to often. However, this was my fault, but as for smoothness and user friendliness, ar all the way. People need to realize that, unless you are in combat or a mall ninja, we are NOT in combat. Ak`s kick a$$, but come on, are you really gonna throw your gun down in the mud or run it over with a car? With the ar, just keep the freaking dust cover closed when not in use. BOTH rifles excel and are excellent. 2 different countries, 2 different rifles. Its chevy vs ford. Get what you want and love it for what it is. For me, its my ar with 2 different uppers. However, if i get the cash….and my wife lets me…..ill buy an ak in a heartbeat. Also, an ar is a model, an ak is an old woman. You can, mmmmm, do both, but the ar is more pleasent/fun lol (tighter tolerances)

    I love my AR baby girl. What she lacks in stopping power she makes up in accurate at a distance. which a wise man needs to be at I choose the AR. My AR just looks like a sexy slim girl that i want to lick however the AK is a healthy woman that needs no loving and will cook every night. If you need to move fast AR, if you need to wage war AK!
