M40 is a U.S. Marine Corps bolt-action sniper rifle based on the Remington Model 700/40X family, chambered for the 7.62×51mm NATO cartridge. It is a manually operated rifle fed from an internal magazine and configured for precision fire with a telescopic sight. It is best known as the USMC’s standard sniper rifle during the Vietnam War and as the starting point for the later M40A1 series of rebuilt rifles.
HISTORY
During the Vietnam War, the U.S. Marine Corps sought a standardized sniper rifle and selected a military adaptation of the Remington 40X/Model 700 action, adopting it as the M40 in the mid-1960s. Early rifles were typically fitted with variable-power Redfield scopes and issued as a complete sniper system intended to improve consistency and logistics compared to ad hoc rifle-and-scope combinations. Operational use soon revealed weaknesses in the original all-wood stocks—especially warping under heat and humidity—which could affect zero and reliability in the field.
In the early 1970s, Marine Corps armorers at Quantico began rebuilding surviving M40 rifles into the M40A1 configuration. The rebuild program replaced the wood stock with a fiberglass stock and updated optics and fittings, improving durability and stability for precision shooting. These changes established the pattern for the long-running Marine sniper rifle lineage that continued through later M40 variants.
