I am looking for AR-10A Gen 1 m14 based Armalite 5/20 magazines.
These are different from the already hard to find Armalite AR-10B magazines.
These are also different from the plentiful DPMS/SR-25 based magazines.
I contacted Irunguns but any long shot advice I will take.

Thanks for giving this a read.
 
IRG deals with DSArms who list the gen 1 on their website (not IRG's website). Perhaps you can buy them and have them shipped to IRG for import?
 
Like these?

The 1 you have looks like a AR-10B magazine and would not work. The flat back one is closest except the ones I have which work all have a raised small square at the top of the flat spine and look like m14 magazines more closely.

From what I understand the 5 flat backed mags I have are exactly the same as an M14 mag, except for not having the rectangular tab on the back as the AR 10's didn't need that.
What kind of firearm are you wanting to use them in?

Are you looking for the old AR10 waffle mags? because the AR10A uses the waffle mag, AR10B is the M14 based magazine that was introduced during the assault weapons ban, when Armalite was prohibited from manufacture any new AR10A mags, so they retool the AR10 lower to accept surplus M14 mags that was readily available on the market during the ban.

All new AR308 rifles like DPMS/SR-25/Magpul uses the original AR10A magazines dimensions,so they will work in AR10A, unless you going for the waffle mag look, in that case good luck with your search because they were meant to be disposable what ever samples that have survived usually commands a premium price.

TECHNICAL NOTE 101: VISUAL DIFFERENCES AMONG

M15, AR-10A, AND AR-10B COMPONENTS

Armalite AR-10A versus AR-10B

The AR-10A family of ArmaLite® firearms is functionally identical to our AR-10B family. Operation, controls, and maintenance are the same. However, the AR-10A family is designed to accept early ArmaLite AR-10 “Waffle” magazines and good quality magazines copied from them, instead of ArmaLite’s proprietary aluminum magazines that are used in our AR-10B family. Neither family of firearms will function correctly with the other family’s magazines.
The AR-10B magazine is based on the magazine of the famed M-14 rifle. This magazine was adopted during the period of the “Assault Weapons Ban”, during which new Waffle magazines couldn’t be legally produced. The AR-10B magazine has proven to be as supremely successful in the AR-10B as its predecessor was in the M-14, and ArmaLite will continue to offer it.
We have tested, we recommend, and we ship polymer Magpul PMAG® 20LR magazines with our AR-10As. Other similar derivative magazines such as the KAC, M110, and DPMS / Remington 19 round magazines may fit and may function, but we have not tested them so we can’t assess their reliability. You can purchase extra PMAG®s from our website.

I have what I believe is a difficult to source magazine. It is an Armalite AR-10A stamped law enforcement/military lower with Armalite upper. Perhaps I am explaining the type of magazine I need wrong. My apologies. It will not accept SR-25/PMAG magazines. It will not accept Armalite magazines with the long spine ie the 1 the previous guy has shown. The 4 magazines I have which work are Armalite stamped and have the square/rectangular object which sticks out at the top of the spine of the mag. Perhaps someone can explain the exact sort of magazine I am in search of if it is not Gen 1 or the AR10B magazine.

If I'm reading you correctly, I think you're looking for the Gen 1 M14 conversion mags. You used to be able to buy an upgrade kit from Armalite to adapt M14 mags to be used in an AR10. I think you could even, at one point, send in M14 mags and Armalite would modify them for you.

But even an unmodified M14 magazine will fit in an AR10 lower.....it just won't lock in place unless the groove is milled in the side of it. So I don't know why the 'new' Armalite 'm14 style' mags wouldn't fit in your rifle. And there's no reason that a Gen 2 magazine wouldn't fit in your lower, because the lower was originally made to fit an M14 magazine ;)



Silly question......have you actually verified the new Armalite magazines (or the dpms style) don't fit?

Can you post any pics of the lower?

Hello. No silly questions as everyone is attempting to help me. I am selling an Armalite 5/20 right now bc it won't fit. It will slide in but brute force is needed to lock it in and brute force to rip it out. I have bought Pmags before and they won't even enter the magwell. I have 4 working magazines with Armalite base plates. They have the square at the top of the spine. They work perfectly. I am looking for these.
 
I don't have the ability to post pics but the magwell appears like a normal channel. If anyone cares to Google as I can not seem to post via my phone and work is locked out you can easily see an image of the small raised rectangle pattern m14 pre ban magazine if you Google image "Armalite ar-10 m14 magazines." It is not waffle type. I believe Malice has the type down pat whatever it is referred to as.

So, do your magazines have the cutout in the back for the bolt stop? Or do yours lock open the bolt mashing into the follower? (when the bolt is locked open via the mag, does it drop when you remove the mag?)


Yours look like the top one I assume?

There's really no reason that both shouldn't work in your lower (although seemingly they don't). It might be worth a call to Armalite to inquire what's up.

Can you tell where the interference is with the AR10B Gen 2 mags? Is it the actual mag well that has the interference or are the mags bottoming out in the upper?

The thing that doesn't make sense to me is you say your lower is Stamped AR10A........which means the Pmags should fit, but they don't. So that would make it an AR10B.

It's too bad you can't post pictures because I'm super curious as to what's going on.

Sad to say but there's a few in Canada couple owners own some but ArmaLite does not make them anymore they only sending the 10 rounders flush cuts I've talked to Evan at Wolverine supplies a lot about it and ask them to bring in a lot I cancelled orders because they couldn't get the twenties
 
Yes my magazines look like the top one. These are what I am trying to source. I can email a pic if you have an email you'd care to PM me with of my lower. I believe although it is an AR-10A model that it is an early model and possibly incorrectly stamped in that it will not accept SR-25/Pmag/ long spine magazines. It will only accept converted m14 magazines with the square on the back. I was told by a Gunner far more knowledgeable than me after sending pics that I had an AR10-A4 lower with AR-10B upper. I am not sure if that contributes to the magazine dilemma? Anyway if any Gunners know where to find (even in the States) this type of magazine I would appreciate it.
