is there another brand of mag that will work in my armalite ar10 outside of going with armalite mags ?

No. Armalite uses a proprietary magazine.

During the assault weapons ban, some people modified M-14 magazines with mixed results.

Depends on if its the older AR10B or the new AR10A. The new ones take P mags.

Yes and no.

The beginning of 2012 ArmaLite released a new model of the AR-10. Called the AR-10A, this model uses SR-25 magazines, Pmags are SR-25 mags, LMT, CMMG, KAC and others use SR-25 mags and they are the defacto standard now.

The earlier models of the AR-10, refereed to as the AR-10B, use a proprietary mag based of the M14 magazine. These mags were first use back during the AWB so the user could have a high capacity magazine. These are available in 5, 10, 20 and 25 rd versions and cost a few dollars more than Pmags, $25-$35.

Other 7.62 AR platforms use FAL mags, and G3 mags.

If you have a AR-10B then use only ArmaLite GenI or GenII mags. There are some aftermarket AR-10B mags but they have a dismal reliability record, plus they cost more than the real deal.

ok another dumb question my gun just says ArmaLite AR10, theres no A or B following the AR10 stamping. the serial # is 388XXX how do i know if its an A or B version ? or do i need to make a call to ArmaLite them selves ? im pretty sure its a B version from what im seeing on there web site.
Thanks for helping me figure this out.

Look at the side of your magazine. The 10B m14 mags have a window on the left side. The early pre-ban are made off M14 mags and have the lug on the back. The newer GenII AR-10B mags have the spline the full length.
