M1D Garand Sniper

About the M1D Garand Sniper

The M1D Garand Sniper is an improved sniper variant of the M1 Garand semi-automatic rifle, adopted as 'substitute standard' by the U.S. Army in September 1944. The M1D addressed the M1C's primary limitation by using a simpler Springfield Armory single-ring scope mount attached to the barrel rather than requiring drilling and tapping of the hardened receiver. This barrel-mounted system used a special M1D barrel with an integral mounting block, making conversion of standard M1 rifles far quicker and more economical. The M1D became the primary U.S. sniper rifle during the Korean War, equipped with the standardized 2.2x M84 telescopic sight.

The M1D became the workhorse sniper rifle of the Korean War, where the mountainous terrain and long engagement distances made precision shooting essential. American snipers armed with M1D rifles engaged Chinese and North Korean forces at ranges that tested the limits of the 2.2x M84 scope, often firing from elevated positions across valleys and ridgelines. The semi-automatic action gave U.S. snipers a critical edge during Chinese human wave attacks, where the ability to deliver rapid follow-up shots meant the difference between life and death.

M1D Garand Sniper specifications

The M1D was originally designated the M1E8. Although adopted in September 1944, no M1D rifles were produced during WWII. Production and conversion of existing M1 Garands occurred primarily during the Korean War era. The barrel-mounted scope design meant the scope could be installed without removing the iron sights, allowing the shooter to use either optic or iron sights. The 2.2x M84 scope featured sealed optics, protective metal covers on adjustment knobs, and a sliding light shade. The M1D served as the U.S. military's primary sniper rifle until replaced by the M21 (accurized M14) in the mid-1960s.
