The Deck Sweeper Stunning Blaster, a stun blaster, was created by Merr-Sonn Munitions, Inc. in the era of the Galactic Civil War. This weapon, which had no lethal firing mode, was derived from the Firespray DL-87 stun rifle made by BlasTech Industries. Its purpose was to incapacitate numerous individuals simultaneously; the weapon's front featured a wide barrel that discharged a forty-five degree arc with a range extending to ten meters.
Sales of the Deck Sweeper were limited to law enforcement agencies and military organizations, intended for use by riot control units and customs boarding teams. Although civilian ownership was prohibited, pirates and privateers favored it as a weapon for boarding actions. The Galactic Empire declined to adopt the Deck Sweeper for use by the Imperial Navy, pointing to its limited range and low firing speed. The weapon's large dimensions also played a role, with Imperial commanders judging it unsuitable for stormtroopers and marines.
