Thoroughly clean your flint gun, and flush the breech, without removing your vent liner. Simply remove your flint lock. Install the clamp, with the O-Ring centered over the vent.

Place the bottom nozzle in a container of water. Add only one drop of liquid detergent to each quart of water.

Place a wet cotton flannel cleaning patch on the muzzle, and slowly wipe the bore, using your ramrod and cleaning jagged tip. Air will be expelled as you press the ramrod down. Water will be drawn in, as you pull the rod, slowly, without removing it from the barrel.

Grasp the muzzle with a cloth, to catch any drips. Pump the ramrod up and down the bore, slowly. After several cycles, change to clean warm water, with no detergent, for a final flush.

Our Flint Flush Cleaning Tool will fit small barrels and large barresl, up to 1-7/16" round or octagon, including the big 10 gauge guns, First Model Brown Bess.

The large rubber o-ring works well with White Lightin' vent liners, Ampco vent liners, Stainless vent liners, hex vent liners, Caywood coned vents, traditional drilled vents, and original Nock's patent inside coned vents.
