Notes
The M40A6 features a Remington 700 short action bedded into a fiberglass-composite stock with aluminum bedding block. The rifle is compatible with the AN/PVS-22 and AN/PVS-30 night vision devices. Each M40A6 is required to shoot sub-MOA groups at 300 yards during acceptance testing. The M40 series is being gradually supplemented by the Mk 13 Mod 7 in .300 Winchester Magnum for extended range capability.
Background
The M40 lineage is one of the longest-serving sniper rifle platforms in any military, with USMC Scout Snipers using variants of the Remington 700-based system continuously since 1966. Carlos Hathcock, the legendary USMC sniper with 93 confirmed kills in Vietnam, used the original M40, cementing the platform's iconic status in military sniper history.
