Prototype Jungle Carbine: A No1 MkV Becomes a No5 MkI
This review details a rare No1 MkV prototype converted into an early No5 MkI 'Jungle Carbine' configuration. Key features include its receiver-mounted aperture sight, a modified front end with a flash hider and bayonet lug, and a unique hollowed bolt handle for weight reduction. The prototype's development in 1943 aimed for a lighter service rifle, but ultimately, the No4 rifle was chosen as the basis for mass production due to existing manufacturing infrastructure.
