Our small brass flint lock priming valve has a knurled body, which may be glued to a 19/64" hole in your wood, horn, or antler priming flask. Drill deep enough to hold a quantity of priming powder.
The valve spout unscrews, to allow refilling through the brass body, using a funnel. Use FFFFg black powder, for priming only.
Best quality, solid brass, made in the USA, this tiny valve squirts three grains weight of priming powder, each time the nozzle is pressed into your rifle, fowling gun, or musket's flash pan.
