I have three pre-ban 40 round AR-15 mags. These appear to be steel, and are blue/black. I have never used, loaded or inserted these into a gun. Been in my safe since the 1980's.
Asking $100 shipped for all three, or best offer. Feed free to make an offer, I have no use for them. They are sold AS-IS and have no makers marks at all.
Discreet PayPal OK. NO shipment to NY, NJ, MA, MD or CA. Know your local laws. No shipment where illegal.
Again, if the price is too high fee free to make an offer.
