The Mk13 Mod 7 is a Remington 700 placed into an Accuracy International Chassis system. The Marine Corps employs tons of semi-auto sniper rifles, but they also field a series of unique rifles that date back to 1966.
While a lot of the professional sniping community moved to semi-auto platforms, the Marine Corps clung to its bolt guns! Well, kind of. Marines also used ACOGs on these rifles, but the fixed 4X limited the Marine’s long-range precision accuracy.
The most common being the TS-30A2, aka the Leupold Mark 4 M3 3-9×36 scope. The Marine Corps then tossed on a bipod, and a variety of day optics were utilized along the way. BLT 1/6 is the ground combat element of the 22nd Marine Expeditionary Unit (Special Operations Capable). A designated marksman from Alpha Co., Battalion Landing Team 1st Bn., 6th Marines surveys the area around his task force’s headquarters in Khas Oruzgan, Afghanistan during Operation PEGASUS. Burst triggers suck and decrease the accuracy of the shooter by being crappy triggers (their break weight changes). They made use of an M16A4 with a free-floating rail system, a stainless steel match grade barrel, and an M16A1 trigger assembling. The Marine’s unique rifles were assembled at the Precision Weapons Section of the Weapons Training Battalion out of Quantico. Marines from Golf Battery, Battalion Landing Team 1st Bn., 6th Marines, the ground combat element of the 22d Marine Expeditionary Unit (Special Operations Capable), aim in during a live fire exercise in Albania during the MEU’s recent amphibious landing exercise (PHIBLEX). The SAMR came from the Marine Corps Warfighting Laboratory to produce a modern designated marksman’s rifle equipped with a higher-powered optic for long-range precision. SAM-R Stands for Squad Advanced Marksman Rifle, and this USMC invention predated the Marine Corps adoption of the Mk 12. The Marines faster firing rifles, and the fact they carried more ammo allowed them to make the most of their numbers. This proved quite handy in the Spanish-American war, where the outnumbered Marines outshot the Spanish Mausers during the race for Cuzco Well. 6mm Lee Navy ammunition was lighter, and the Marines could carry more of it. This straight-pull bolt action rifle offered a faster action than the Krag and chambered an early smokeless cartridge called the 6mm Lee Navy. While the Army utilized the Krag, the Marines and Navy used the more modern and more capable Lee Navy rifle.
