B.I.D. CO2 Kit (Blowoff-Inflator-Discharger) new design allows you to use just one simple adapter for discharging and unloading of your flintlock, percussion side hammer and break-action in-line muzzleloaders. Designed to work on flint, #11 or musket nipples and 209 shotgun primer muzzleloaders. For added safety use between shots to clear barrel and remove any residual sparks or embers prior to reloading. This new design also makes the B.I.D. kit useful as a blowoff cleaning device for trigger mechanisms, etc. Each B.I.D. kit contains a CO2 dispenser, discharge nozzle with two tips, one for discharging and inflating, and a smaller blowoff muzzle, three 16 gram CO2 cartridges, and a convenient carry pouch.
