I have a new and unused beta C-Mag for the AR-15 platform. This is the 100 round magazine that works well in the AR platform. This is the 5.56mm/.223 version and comes complete with the carry pouch, manual, loader and all the parts that came with it originally. I thought I wanted one and when I got I decided I dont shoot my AR's so why have a 100 round magazine. $250.00 plus any shipping costs if needed. Located in the Raleigh area. Thanks for looking.
