(48th) Long #438; Bolt action, Barrel length 775 mm; Cal .303 British (7.7 mm); magazine (5 round capacity); Bayonet
For all practical purposes, the Mk III was an entirely new design. It incorporated the 30.5 inch barrel and flag safety of the Mk II**, taking that re-design much further. The internal double-stack magazine was replaced with an exposed single-stack magazine. The “dump loading” lever was gone, and a charger guide was added for loading with stripper clips. A magazine cut-off was employed, but the design that lowered the magazine shell was discarded and replaced by one that restricted the rearward travel of the bolt. The bolt-stop plunger was replaced by a flag lever with 3 positions (cut-off enabled, bolt release, cut-off disabled). The bolt was far sturdier and had multi-thread locking lugs. A new rear sight designated the “Ross Battle Aperture” was installed on the bridge of the receiver rather than on top of the barrel. World War I increased demand, and at least 235,540 were produced for Canadian forces.
