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.
