OK guys and gals, we have a VERY small number of extra Alexander Arms magazines, however the mags we got in had their rivets installed too low. The US exporter who pinned the magazines apparently didn't realize that Alexander Arms nipped down the followers in some of the mags for no apparent reason, so I've permanently built up the follower using epoxy to avoid putting extra holes in the mag body. Rest assured I've manually tested the magazines to make sure they function 100% and cannot fit more than five (5) rounds of .50 BEO. Full warranty return if you're not satisfied with the magazine.
I know there'll be some disappointed people out there who don't catch one of these very few magazines, but rest assure guys, we're working on getting a steady supply of these mags.
