About the M40A5
The M40A5 is a bolt-action sniper rifle chambered in 7.62x51mm NATO, produced by Remington Arms since 2009. This American-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 5-round magazine capacity, this sniper rifle offers compact firepower. The striker-fired action provides a consistent trigger pull for every shot, simplifying training and reducing the manual of arms - a design philosophy that has become the dominant paradigm in modern defensive handguns. The 24.0-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. At 7480g (263.8 oz), this is a substantial firearm whose weight contributes to reduced felt recoil and enhanced stability during precision shooting. The steel frame provides a solid, premium feel with the durability to withstand decades of regular use and thousands of rounds. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.
The M40 rifle series has been the USMC's standard sniper rifle since the Vietnam War, when the Marine Corps ordered 700 Remington Model 40x target rifles and assigned them the M40 designation. Every M40 variant since has been hand-built at Quantico by USMC armorers, making it one of the few military weapons that is custom-assembled for each individual rifle rather than factory mass-produced. The M40A5 carries forward this tradition of craftsmanship, with each rifle built to sub-MOA accuracy standards.

Unlike mass-produced military rifles, each M40 is individually built to exacting standards by USMC armorers at Quantico. The M40 series has been in continuous USMC service since 1966, making it one of the longest-serving sniper rifle platforms in any military. The M40A5 weighs approximately 8.59 kg (18.94 lbs) when fully equipped with scope, bipod, sling, and loaded 5-round magazine, and approximately 9.18 kg (20.24 lbs) with sound suppressor installed. The overall length with suppressor is 1,356mm (53.37 inches). The Philippine Marine Corps received 85 M40A5 rifles delivered in 2017, which saw service during the Siege of Marawi. The M40 series is being gradually replaced by the Mk 13 Mod 7 chambered in .300 Winchester Magnum for greater range capability.
