AR-AK

[mcmurry]

Didn't I see a magazine ad for an AR that uses the AK mag and shoots the AK round? Has anyone shot this rifle? How did it perform?
Thanks.

most likely it was the rock river arms version but supposedly colt is working on such a design as well.. a little unnecessary in my opinion as the only problem with standard x39 ARs is the magazines usually have bad followers and springs but what the heck, if it's going to be a dedicated rifle the no problem making a dedicated lower that can take cheap AK mags.

I do find the idea kindof ludicrous that people don't like cheap AR lowers that require expensive mags because they may cause reliability issues and therefore opt for an expensive lower so they can take cheap unreliable magazines...?

Colt makes one. The CM901. Colt just received a contract for a foreign military, x39 version, takes standard AK mags with angled(chopped) magwell and monolithic upper.

Are you claiming there are more reliable mags than the Comblock AK magazines?

 

[Bartholomew Roberts]

A 10lb bare bones rifle in an intermediate caliber? I don't think even the .308 CM-901 weighs that much.

 

[tahunua001]

I guess I should have said cheap POTENTIALLY unreliable mags but yes, I have had numerous failures with numerous mags in numerous rifles... the potential is there just as much as the guys using junk AR mags.

Are you claiming there are more reliable mags than the Comblock AK magazines?

Yes. Suomi mags. Possibly VZ58 mags as well (because they are essentially the same thing, only aluminum and more nicely made)

from what i've heard about the ar15 that are chambered for the 7.62x39 round is not as reliable. could be the magazines they designed to work with the ar lower... that's why they came out with the 300 blackout. i'm building one myself.

Yes. Suomi mags

Based on what experiences? How many guns using Suomi mags are out there? Used from Siberia to the desert? Compared to how many guns using AK mags?

Possibly VZ58 mags as well (because they are essentially the same thing, only aluminum and more nicely made)

Again how many in real world use? Being basically AK mags they could be as reliable, but I don't see making them out of aluminum as enhancing reliability My samples of VZ58 mags don't seem "more nicely made" in any way -- just lighter (aluminum) with a tab to activate a BHO device.

considering that the 6.5 grendel AR is identical to the x39 AR with the exception of barrel and magazines and they are 100% reliable, it is a fair assumption to say that it's the magazines. my brother struggled with reliability for about a year before he got new springs and followers for his mags, now it's 100% reliable. I had the same problem with my 9mm until I bought quality magazines. the main problem with many specialty ARs is the magazines.

The OP specifically asked about the versions of the AR-15 which are designed to use AK mags. Totally different.

current production AR type rifles that use AK magazines:
Colt CK901
MGI MARCK-15
Rock River Arms LAR-47

Yes. The older 7.62x39mm AR-15's had straight magwells, so the magazines had to have a long straight section at the top in order to fit the magwell. The problem is that 7.62x39mm is a very tapered round and really didn't work well with that geometry.

AK 7.62x39mm magazines are smoothly curved and are arguably some of the most reliable magazines in existence, so an AR variant that use actual AK magazines should be far more reliable.

Knight's Armament had some success in Afghanistan with a special upper for SF units.. don't think it was available to the public though.

 

[carbine85]

So what's the advantage of this rifle over a modern well built AK? What's to be gained?

 

[Ian]

Three pounds, that's what.

 

[MAKster]

The Colt 901 is heavy because of the monolithic upper receiver with railed handguard. If you put a quad rail on any other AR or AK it would add weight as well.

 

[vaupet]

Sig 556 xi takes 'AK-style' magazines in the 7.62*39 version

 

[Cal-gun Fan]

Not 3lb it wouldn't, especially w/the ak.

 

[Bartholomew Roberts]

9.9lbs for a 16" carbine CM901 in 7.62x39. You can add the cheapest, UTG chunk of steel 12" quad rail to an AR and you still won't be close to 9.9lbs. With some of the new alloy keymod handguards, you can actually have a 12" handguard that weighs about as much as a plastic carbine hanguard with delta ring and barrel nut.

KAC SR-47. Only 7 were made.
