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 a limitless variety of accessories. Low-pressure electropneumatic operation replaces the outdated spring and hammer designs that power competing tactical markers and allows the SP-1™ to deliver a fast, accurate and quiet hailstorm of paint.
