New design now allows you to use just one simple adapter for discharging and unloading your flintlock, percussion sidehammer, and break-action in line muzzleloaders. Works on flint, #11 or musket nipples, and 290 shotgun primer muzzleloaders. Also use for safety to clear the barrel and breech between shots to remove any residual sparks or embers, prior to reloading. New design also makes this tool useful as a blowoff cleaning device by discharging a blast of "air" to easily remove dirt from tight spots such as your computer keyboard, printed circuit boards, enclosed areas etc. Kit contains a CO2 dispenser, discharge nozzle with two tips, one for discharging and inflating, a smaller blowoff nozzle, three (3) 16 gram CO2 cartridges, and a convenient carry pouch.
