I have 5 WE open bolt Co2 magazines that im looking so sell so i can get some green gas mags, one of them dose not work and I'm just selling it for $5, 2 of them work with no problems and I'm looking to get about $30 each for them, the last 2 work fine but are missing the bolt catch tabs so your bolt catch wont work with them and I'm looking to get about $20 each for them. PM me if you are interested. I will also accept trades for green gas mags.
