The M24 Sniper Weapon System (SWS) or M24 is the military and police version of the Remington Model 700 rifle, M24 being the model name assigned by the United States Army after adoption as their standard sniper rifle in 1988. The M24 is referred to as a "weapon system" because it consists of not only a rifle, but also a detachable telescopic sight and other accessories.
A designated marksman (DM), squad advanced marksman (AD) or squad designated marksman (SDM) is a military marksman role in an infantry squad. The term sniper was used in Soviet doctrine although the soldiers using the Dragunov SVD were the first to use a specifically designed designated marksman rifle. The analogous role in the Israel Defense Forces is sharpshooter.
The Advanced Combat Optical Gunsight (ACOG) is a series of prismatic telescopic sights manufactured by Trijicon. The ACOG was originally designed to be used on the M16 rifle and M4 carbine, but Trijicon has also developed ACOG accessories for other firearms. Models provide fixed-power magnification levels from 1.25× to 6×. ACOG reticles are illuminated at night by an internal tritium phosphor. Some versions have an additional daytime reticle illumination via a passive external fiberoptic light pipe or are LED-illuminated using a dry battery. The first ACOG model, known as the TA01, was released in 1987.
The United States Navy Mk 12 MOD 0/1/H Special Purpose Rifle (SPR) is a designated marksman rifle that was in service with United States Special Operations Forces in the designated marksman role until 2017, also designed to be shorter than standard weapons. SPR initially stood for Special Purpose Receiver as it referred to an add-on upper receiver assembly, but that nomenclature changed to Special Purpose Rifle as the weapon became a stand-alone weapons system.
The M40 rifle is a bolt-action sniper rifle used by the United States Marine Corps. It has had four variants: the M40, M40A1, M40A3, and M40A5. The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009.
The United States Marine Corps Designated Marksman Rifle is a semi-automatic, gas-operated rifle chambered for the 7.62×51mm NATO cartridge. It is a modified version of the M14 rifle formerly used by the United States Marine Corps. The USMC Precision Weapons Section at Marine Corps Base Quantico built all DMRs.
The Squad Designated Marksman Rifle (SDM-R) is an American designated marksman rifle used by the United States Army. It is essentially a heavily modified M16 rifle designed to provide U.S. Army designated marksmen greater accuracy and firepower at longer ranges, increasing an infantry squad's effective range to up to 600 meters.
The Mk 14 Enhanced Battle Rifle (EBR) is an American military selective fire battle rifle, and a designated marksman rifle chambered for the 7.62×51mm NATO cartridge. It is a variant of the M14 battle rifle and was originally built for use with units of United States Special Operations Command, such as the United States Navy SEALs, Delta Force, and task specific Green Berets ODA teams/units.
A designated marksman rifle (DMR) is a modern scoped high-precision rifle used by infantry in the designated marksman (DM) role. It generally fills the engagement range gap between a service rifle and a dedicated sniper rifle, at around 300–600 metres (330–660 yd).
The SR-25 is a designated marksman rifle and semi-automatic sniper rifle designed by Eugene Stoner and manufactured by Knight's Armament Company.
The M110 Semi Automatic Sniper System is an American semi-automatic sniper rifle that is chambered for the 7.62×51mm NATO round. It is manufactured by Knight's Armament Company, developed from the Knight's Armament Company SR-25, and adopted by the U.S. military following the 2005 US Army Semi-Automatic Sniper Rifle competition.
The Marine Scout Sniper Rifle (MSSR) is a Philippine semi-automatic designated marksman rifle developed by the Philippine Marine Corps for their Marine Scout Snipers. Designed in the mid-1990s to replace severely-outdated battle rifles then used as marksman rifles, the MSSR is essentially an M16A1 that has been heavily modified and accurized to serve as a marksman rifle.
The M39 Enhanced Marksman Rifle is a semi-automatic, gas-operated designated marksman rifle chambered for the 7.62×51mm NATO cartridge. It is a modified and accurized version of the M14 rifle used by the United States military, in a similar vein to the Mk 14 Enhanced Battle Rifle. It is based on the United States Marine Corps Designated Marksman Rifle (DMR), which it replaced. It is manufactured by Sage International and maintained by the USMC's Precision Weapons Section.
The M27 Infantry Automatic Rifle (IAR) is a 5.56mm, select-fire assault rifle, based on the HK416 by Heckler & Koch. It is used by the United States Marine Corps (USMC) and is intended to be issued to all infantry riflemen as well as automatic riflemen. The USMC initially planned to purchase 6,500 M27s to replace a portion of the M249 light machine guns employed by automatic riflemen within Infantry and Light Armored Reconnaissance Battalions. Approximately 8,000–10,000 M249s will remain in service with the Marine Corps to be used at the discretion of company commanders. In December 2017, the Marine Corps announced that it would equip every member of an infantry squad with the M27, supplanting the M4 carbine which would be retained at the platoon leadership positions and above.
The L129A1, also known as the L129A1 Sharpshooter Rifle, is a 7.62×51mm NATO designated marksman rifle manufactured by Lewis Machine & Tool Company (LMT) for the British Armed Forces.
Lewis Machine & Tool Company (LMT) is an American armaments company founded by Karl Lewis, in 1980. LMT manufactures weapon systems including a variant of the M4 carbine and the M203 grenade launcher. LMT products are used by the military forces of the United Kingdom, New Zealand, Estonia, and the United States. LMT formerly produced forged FAL receivers for Illinois-based DS Arms.
M110A1 may refer to the M110A1 CSASS or the M110A1 SDMR. It is an American semi-automatic sniper rifle that is chambered for the 7.62×51mm NATO round. It is manufactured by Heckler & Koch (H&K) and developed from the company's HK417, and similar to the Bundeswehr G28 configuration. Despite a designation similar to the M110 Semi-Automatic Sniper System, the M110A1 is an unrelated design as the former was a development of the Knight's Armament Company SR-25. The M110A1 CSASS was expected to supplant and eventually replace the M110 in U.S. military service but this does not appear to have occurred as of 2022. However, several thousand M110A1 SDMRs have been fielded with the US Army and Air Force to replace various weapon systems currently being used.
