Springfield Armory M1D Garand rifle
The M1D was a variant of the Garand rifle fitted with an offset M84 telescopic sight. As the optic was mounted to the left of the bore, a padded leather cheekpiece had to be attached to the buttstock to allow shooters to get consistent sight alignment. The M1D was developed from the M1E8 rifle designed at Springfield Armory and adopted as a substitute standard in September of 1944.
Originally the M1E8 was designed to be fitted with a Lyman M73 telescopic sight similar to that employed on the bolt-action M1903A4 sniper rifle. Later versions of military issue Lyman scopes were designated as M81 (cross-wire reticle) and M82 (tapered post reticle) variants.
