The TACAMO Arc loader features dual channels for the fastest feeding gravity loader on the market. Designed specifically to work with blow back markers, our unique "arc" design prevents paintballs from being blown back "up the stack" in the feed port. Our dual channels assure you that you have a minimum of 8 rounds inline whether shooting uphill or down hill. The arc also directs the weight of paintballs away from the feed tube which is the main source of jams in every other gravity loader made.
