I have a 10/22 and a Winchester Wildcat that takes 10/22 mags, so was a good chance to stock pile a few spare mags for them.
The AR mags are 5.56/.223 30rd poly mags made in the USA by Amend2 and also were $10 each. I honestly would have preferred 5 or 10 round mags for my bolt .223, but those are quite scarce right now.
Academy on I-240 had Magpul AR mags 5rd & 10rd when I was there this morning scrounging for ammo.
