Abstract: A naturally illuminated three dot sighting system for firearms includes a rear sight having two dots formed by scintillating fibers encased in an optically clear polymer block, and a front sight having one dot formed by a scintillating fiber within an optically clear polymer post. The rear sight has a center channel with scintillating fibers disposed on each side thereof. In poor ambient light, the light incident on the optically clear blocks travels to the fibers which gather such light and scintillate to provide dots of light at their proximal ends which can be aligned.

Abstract: A nipple for use in igniting a propellant charge in a muzzle loading firearm employing percussive ignition caps, has an elongated body with a generally cylindrical cap receiving portion adjacent one end and a mounting portion adjacent the other end. The outer surface of the cap receiving portion is cooperatively dimensioned and configured to slidably seat percussion caps thereon. The body has a passage extending axially therethrough with a generally funnel shaped inlet portion extending axially from the one end through a major portion of the length of the body. The funnel shaped inlet portion tapers radially inwardly from the one end towards the other end at an angle less than 25.degree. relative to the longitudinal axis of the passage, and the throat portion has a generally uniform cross section corresponding to the smallest cross section of the inlet portion.
