Hi all, Hopefully some SME can give me some guidance on this question. Are there any other manufacturers, besides Armalite, that are making AR-10 upper receivers that are compatiable with the M14/M1A style magazines? Thanks for any info on this!

the lowers are what determine the magazine type.

I can't find it in Armalite's tech notes on their site right now, but I thought it indicates the upper changed too to accommodate the SR25 pattern mags.  I may be wrong.

Edit: I think I may have found it...maybe?

I have the older version AR10 rifle that utilizes the modified M14 magazine.

Magazines
There are primarily two magazines styles for the .308 rifles, the original Armalite-Fairchild magazines used in the original AR-10s, then picked up by the KAC SR-25 (henceforth called the SR-25 Type) and the Modern Armalite AR-10 type which is a modified M-14 magazine. It should be pointed out RRA (and formerly Bushmaster) make rifles that use FAL magazines, and CMMG has a lower which uses G3 magazines.

Yeah, someone needs to go through the FAQs and do an update (Tactical Ambush ?), but there was enough info in it for the OP's purposes as is.

Elk Creek Mfg, and one other 80% lower and upper. I lost my bookmarks on my phone, i think it was Elite Tactical Systems?

Elk creek

Elite Tactical

Elk creeks upper looks funny to me. Forward assist is part of the shell deflector. I don't like that.

I'm not sure if elite tactical had uppers, or just the lowers
