Over at Guns.com I did a quick geardo rundown of several of the Corp’s modern sniper rigs from the early WWI Rifle, “USMC Telescopic Rifle, Model of 1917” which is basically just a good shooting early M1903 with a fixed Winchester A5 scope through WWII’s updated M1903A-1 model Springfield with a Unertl 8x scope– immediately distinguishable by its long shade on the objective lens– which they designated the M1941 Sniper Rifle, and then the Korean War’s M1C and the various guns of Vietnam.

“A U.S. Marine Marksman using a telescopic sight and with his Springfield cocked and ready, waits for a troublesome North Korean sniper to pop up so he can pick him off in Seoul, the capital city of South Korea on Sept. 28, 1950. Note the Unertl. (Photo/caption: Max Desfor/AP)
“Pvt. Randall E. Josey, a Marine sniper attached to Co. H, 2nd Bn., 5th Marines, has a bead on a Viet Cong at over 1,000 meters. Using a 3 x 9 power scope, a Remington 700 rifle has accuracy up to 1,100 meters and has been used effectively up to 2,000 meters or more.” June 19, 1967 (Photo/caption: U.S. Marine Corps History Division)
