	During the Vietnam War, the Marine Corps decided they needed a standard sniper rifle. After testing several possibilities, they ordered seven hundred Remington Model 40x rifles (target/varmint version of the Remington Model 700 bolt-action rifle), and gave them the M40 designation. Most had a Redfield 3–9x Accurange variable scope mounted. With time, certain weaknesses, primarily warping of the all-wood stock, became apparent.

	~~Sometime in the early 1970s, the USMC armorers at MCB Quantico began rebuilding the original M40s into M40A1s~~. ~~The process involved, among other improvements, replacing~~ the ~~original wood stocks with McMillan A1 fiberglass stocks~~, ~~as well as replacing~~ the ~~original 3–9× Redfield variable-power scopes with 10× Unertl fixed-power scopes~~. ~~The M40 was originally designed by Jack Cuddy and Neill Goddard~~. ~~The stock featured Wichita sling swivels~~ and a ~~Pachmayr buttpad~~.		'''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.

	~~<gallery mode="packed" heights="400px">~~		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.
