PMI 30 rnd Stainless steel $20 each shipped (I have four) These are probably the best after market steel magazines for the Mini-14 and no longer made. Very lightly used and excellent condition.
Millet 35 round $12 each shipped. (I have three) These are made of polymer and similar to Eagle. Uses unique "coil" spring instead of traditional springs. Also lightly used in excellent condition.
I can take pictures if you want.
