There are staples of weaponry in the armory of the Marine Corps that define the battlefield. One of these weapons is the M40 sniper rifle, which is the premier weapon of choice for the Marine Corps for long-range enemy engagements.

Based off of the Remington 700 bolt-action rifle, the M40 is a bolt-action rifle that fires .308 caliber rounds. The weapon has been in use in the Marine Corps since 1966, with the latest M40A5 variant introduced in 2009. This is the weapon that snipers with the Marine Corps Shooting Team grow accustomed to and are expected to be experts in operating it during competitions, such as the Australian Army Skill at Arms Meeting 2016 at Puckapunyal Military Area in Victoria, Australia.

“The M40 is a great weapon because it’s a bolt action so there’s less moving parts when you’re actually firing the weapon,” said Cpl. John Luze, a competitor with the MCST. “It’s built from the ground up at Precision Weapons Section so the parts fit together better. Being a bolt action, it’s easier to clean and holds a better group than other sniper rifles.”

Considering the expectations of proficiency, Marine snipers learn extensively about the M40 among other things at Scout Sniper Basic Course. The length of time before a Marine is qualified to operate a sniper rifle can vary, according to Luze.
