First Strike has developed some of the best magazine fed paintball markers on the market today! Not only do these work very well, but they are some of the most realistic and tactical paintball guns available. Their two most notable paintball markers are the FSC (First Strike Compact) and the T15. The FSC is a compact pistol which uses a 6 round magazine that is powered by an 8-gram Co2 cartridge. The T15 is a rifle styled marker that uses 20 round magazines and is typically powered by a 13 cubic inch tank concealed in the stock of the marker. Of course all First Strike markers are capable of firing First Strike rounds, they can usually be heavily modified per the users tastes, and look fantastic!
