Did you buy a Colt 9mm Beta C mag for your semi auto Colt 9mm carbine only to find it heavy and boring? Well I have six used Colt 32rd LEO marked mags that I would like to trade. All the mags are in good shape. I have a Colt 9mm Beta C that I use with my M16 RR. There very few things that will put a bigger smile on my face than a 100rd Beta C dump. I would rather have the Beta than the six mags. I'm sure I could sell the mags and buy the Beta. The trade would save me a step. The email button is the easiest way to contact me. Please let me know.
