Designated marksman rifles compared to sniper rifles, battle rifles, and assault rifles

Most designated marksman rifles are based on an assault rifle that is currently issued by a nation's military, or on a battle rifle that was formerly issued. A battle rifle is a semi-automatic or full-automatic rifle that fires 7.62mm NATO or similar full-power rounds. Classic examples include the M14
M14 rifle
The M14 rifle, formally the United States Rifle, 7.62 mm, M14, is an American selective fire automatic rifle firing 7.62x51mm NATO  ammunition. It was the standard issue U.S. rifle from 1959 to 1970. The M14 was used for U.S...

 cartridge during the 1970s and 1980s.

Some nations have also built rifles that were designed for the designated marksman from the ground up.

Sights

All designated marksman rifles will have some type of optical sight with a higher magnification level than the standard issue rifle. For example, the SDM-R

. Sometimes, the sighting system will be the only difference between the standard rifle and the designated marksman rifle, as is the case with the F88S DMR issued to the Australian Army.

Sniper rifles often have even greater magnification than designated marksman rifles, for example, the M110 SASS used by the United States Army, is equipped with a Leupold 3.5-10x variable-power scope. However, some designated marksman rifles, such as the Mk 12 Special Purpose Rifle or the USMC Squad Advanced Marksman Rifle are fitted with scopes with similar magnification.

Barrels

In some cases, the designated marksman rifle will have a longer barrel than the standard issued rifle. However, this is not universally true. In fact, the M16A4 rifle is still standard issue to the United States Marine Corps. The barrel on the Mk 12 Special Purpose Rifle, the current rifle used by the squad designated marksman in the USMC, is only 18 inches long - two inches shorter than the barrel on the standard rifle. Also, some rifles, such as the F88S Austeyr, have a barrel that is the same length as the standard service rifle. The FD-200

 have barrels 18-22 inches long.

Ammunition

In most cases, a designated marksman rifle will share the ammunition used by standard issue rifles. In the U.S. military, designated marksman rifles chambered for 5.56mm NATO have available the 77 grain match-grade Mk 262 Mod 0/1 cartridge that enhances range to roughly 700 meters.

DM rifles using battle rifle cartridges such as 7.62mm NATO or 7.62x54mmR, may issued with standard ball ammunition, or special match-grade loads, such as 7.62mm NATO 'M118LR' sniper round in the U.S. military.

Action

All designated marksman rifles in use today use a semi-automatic action, with some also being able to fire in full-automatic mode.

Some sniper rifles are semi-automatic, though the vast majority are bolt-action.
