When the U.S. was forced into WW II in late 1941, America's infantry troops were not prepared for the scale of combat they would encounter. The country was not prepared to arm hundreds of thousands of new riflemen with the latest U.S. military rifle - the semi-automatic M1 Garand. Several hundred thousand WW I vintage Springfield Model 1903 rifles were pulled out of storage and sent back into war - and both Remington and Smith-Corona used modified original tooling to produce a slightly modernized version of the rifle, known as the M1903A3. Some were fitted with a low-power 3/4-inch tube 2.5x scope, to become the official U.S. Army M1903A4 sniper rifle, while the Marine Corps installed an 8x target scope on select '03 rifles to create their Model 41 sniper rifle. (Hi-Lux Optics produces superb reproductions of both scopes.) Hi-Lux Optics has totally re-engineered this scope design from the inside out, to produce the clearest, brightest and most reliable scope of this type ever manufactured - and we're proud to add it to our lineup of Wm. Malcolm vintage riflescopes. Externally, this scope is the spitting image of the original. Internally, this scope is far superior - and due to the vast improvements Hi-Lux Optics has made, we are referring to the Wm. Malcolm version as the M73G4. Those improvements include high quality multi-coated lenses for superior light transmission and exceptional clarity. The new M73G4 scope also offers more wind age and elevation adjustment than the original. The Wm. Malcolm version provides a total of 60 MOA for both wind age and elevation.
