I have three brand new mec gar mags for sale. One twenty rnd, one 18 rnd flush, and one 10. I bought the two high caps for my sub before I got it and the 10 rnd came with it. I changed the mag catch to beretta as soon as I got it and have no use for them now. I'll take $60 for all three free shipping to lower 48. Or 27 for the 20rnd, 23 for the 18rnd, 13 for the 10rnd shipped to lower 48.
