Electropneumatic Tactical Paintball Marker. A FRESH TAKE ON TACTICAL. With its military styling and ultra-rugged lightweight construction, the SP-1 is built for speed and made to last. With mil-spec accessory rails at every angle and integrated mount points for a stock, the SP-1 is ready for limitless variety of accessories. The SP-1 is also equipped with an integrated tactical flashlight mount right below the barrel, which accepts inexpensive focused beam flashlights at a fraction of the cost of expensive tactical flashlights. Low-pressure elecropneumatic operation replaces the outdated spring and hammer designs that power compting tactical markers and allows the SP-1 to deliver a fast, accurate and quiet hailstorm of paint.
