Factory HK Mark 23 10rd mags that are still in the package. I got a deal on a bunch of them. I don't need them all. I'm looking for $20 each plus actual shipping costs. I also have some used factory HK Mark 23 10rd mags that are in very good condition that I would sell for $17 each. I would prefer a PSMO but will take a check or other MO. I will hold shipping until funds clear my account. If you wish to use Paypal, $21 + shipping for new and $18 + shipping for used. I will concider bulk discounts on buying multipul mags. The email button is the best way to contact me. Thanks for looking.
