Discharger

The discharger consists of a hollow tubular spigot of about one inch diameter terminating in a part resembling the hilt of a bayonet. Over this spigot fits the hollow tail-piece of the grenade. It is fitted to the rifle, in the same manner as a bayonet, over the bayonet standard and foresight block, and is locked in position by a spring-loaded bolt. On firing the propelling cartridge, the gases pass out of the barrel of the rifle, through the spigot, and into the hollow tail piece to propel the grenade.

Sights

A swing over blade front sight is fitted to the left side of the base of the spigot.

A rear sight attachment in fitted to the left aide of the rifle by means of a metal strap and thumbscrew. The body, which is movably attached to the metal strap by means of a carrier plate, is in the form of a metal box about five inches in length, on the forward end of which a V is formed. The other end, facing the firer when the sight is assembled to the rifle, is inscribed with a range scale graduated from 25 to 100 meters in steps of 25 meters. To give the desired range, the body is rotated and the appropriate graduation brought opposite a pointer on the carrier plate. The body is then held in position by a ball and spring detent.
