Most variants of the Garand, save the [[sniper]] variants, never saw active duty.<ref name="Bishop"/> The sniper versions were modified to accept scope mounts, and two versions (the ''M1C'', formerly M1E7, and the ''M1D'', formerly M1E8) were produced, although not in significant quantities during World War II.<ref>{{cite web |last=Ewing |first=Mel |url=http://www.snipercentral.com/m1cd.htm |title=Sniper Central: U.S. Army M1C & M1D |website=SniperCentral.com |access-date=15 November 2005 |archive-url=https://web.archive.org/web/20051025033916/http://www.snipercentral.com/m1cd.htm |archive-date=25 October 2005 |url-status=dead}}</ref> The only difference between the two versions is the mounting system for the [[telescopic sight]]. In June 1944, the M1C was adopted as a standard [[sniper rifle]] by the [[United States Army|U.S. Army]] to supplement the venerable [[M1903 Springfield rifle#Variants|M1903A4]], but few saw combat; wartime production was 7,971 M1Cs.<ref name=nra/>

The procedure required to install the M1C-type mounts through drilling/tapping the hardened receiver reduced accuracy by warping the receiver. Improved methods to avoid reduction of accuracy were inefficient in terms of tooling and time. This resulted in the development of the M1D, which utilized a simpler, single-ring Springfield Armory mount attached to the barrel rather than the receiver. The M1C was first widely used during the [[Korean War]]. Korean War production was 4,796 M1Cs and 21,380 M1Ds; although few M1Ds were completed in time to see combat.<ref name=nra/>

The [[United States Marine Corps|U.S. Marine Corps]] adopted the M1C as their official sniper rifle in 1951. This USMC 1952 sniper's rifle, or MC52, was an M1C with the commercial Stith Bear Cub scope manufactured by the Kollmorgen Optical Company under the military designation: telescopic sight - Model 4XD-USMC. The Kollmorgen scope with a slightly modified [[Griffin & Howe]] mount was designated MC-1. The MC52 was also too late to see extensive combat in Korea, but it remained in Marine Corps inventories until replaced by bolt-action rifles during the [[Vietnam War]].<ref name=nra/> The [[United States Navy|U.S. Navy]] has also used the Garand, but rechambered for the popular at the time [[7.62×51mm NATO]] round and calling it the M1 mod 0&1.The Mod 0 has a metal bushing and during testing was prone to fail and fall out. The Mod 1 was fit with a new barrel; and a piece of plastic to make sure the user didn’t put the original 30-06 cartridge in the gun.
 
A detachable M2 conical flash hider, adopted 25 January 1945 slipped over the muzzle and was secured in place by the bayonet lug. A T37 flash hider was developed later. Flash hiders were of limited utility during low-light conditions around dawn and dusk, but were often removed as potentially detrimental to accuracy.<ref name=nra/>
