In 1996, the original IMI Galil was reworked to fulfill the Designated Marksman Rifle (DMR) role - or squad-level "sharpshooter" - within the inventory of the Israeli Army to become the "Marksman's Assault Rifle Mark 1". With the Galil pedigree in place, the new weapon brought along with it the same support for the 5.56x45mm NATO standard cartridge and its repeat-fire nature though the rifle was further accurized for combat at distance. The designated marksman/sharpshooter of any unit is not a sniper element per se, for he/she lacks the formal training of the art, and is more akin to an infantryman trained for long range combat. As such, the DMR can be called upon to engage targets beyond the reach of the standard infantryman and lay down repeating fire with accurate results. The MAR Mark 1 was developed to fulfill this role within the Israeli Army. Other armies of the world have included this specialist in their doctrines to date - including the Russians, Americans and British.
As a ranged weapon based primarily on medium- to long-distance precision, the MAR Mark 1 is completed with specially refined barrels that are manufactured strictly for the role. Each are chrome-lined and maximized to take advantage of the full power inherent in the 5.56x45mm NATO cartridge, all set within the proven Galil framework (itself based on the Kalashnikov AK family by way of the Finnish Valmet m/62). The MAR Mark 1 retains the original's double-strut folding stock (folding over the right side of the receiver) but sports an adjustable cheekpiece for comfort. The included bipod is adjustable and folds backwards against the foregrip. The curved, detachable box magazine holds 35 rounds of 5.56mm ammunition in a stacked, spring-loaded arrangement. An scope is mounted along the left side of the receiver while iron sights are retained as backup.
The internal function of the MAR Mark 1 is exactly the same as found on the Galil Assault Rifle.
