T/C's Flame Thrower Nipple features an unique design which ignites the powder charge in a muzzleloader through both a direct vent and via side ports that work in conjunction with the inner breech plug surface to throw a ring of fire. It achieves the hottest ignition possible whether you are using the No. 11 cap or a musket cap. Made of stainless steel these nipples are carefully machined and long lasting.
