« The MAR-10 is a powerful marksman weapon used by CTRG forces. This semi-automatic rifle is chambered in .338 Lapua Magnum. With its 66 cm long barrel and 4.4 kg weight, MAR-10 isn't easy to handle, but high power and extreme precision with effective range up to 1700 m compensate it.

The MAR-10 is a .338 marksman rifle primarily used by CTRG operators and in limited numbers with Mediterranean NATO forces in ArmA 3. It was added with the release of the Marksmen DLC.


The MAR-10 is a piston driven, semi-automatic marksman rifle chambered to fire the .338 Lapua Magnum round.

It loads from 10 round box magazines and can attain a fire rate of up to 250 rounds per minute, with a muzzle velocity of 915 m/s. It can accept accessories on all three rails; top, side, and underbarrel, and can have attachments mounted onto its muzzle.


Ready and waiting.

In terms of performance, the MAR-10's damage output is somewhat underwhelming at close and medium ranges due to using a smaller-sized cartridge compared to its CSAT counterpart (8.6 mm versus 9.3 mm).

But consequently, the MAR-10 has a better ballistics model as it retains much of its power regardless of distance. This is in contrast to the Cyrus, which suffers from a significant damage drop-off for targets beyond 700 metres.

When it comes to accuracy, the MAR-10 is fairly precise and can be used to take out targets at ranges of up to 1,000 metres with little-to-no dispersion. In that aspect, it is almost on-par (though not exactly the same) with sniper rifles like the M320 LRR, making it perfectly suited for use in sniper engagements as opposed to short range firefights.


  • Black: Matte black paint finish.
  • Camo: Custom two-tone splinter camouflage pattern inspired by the Arid Dazzle pattern uniforms worn by CTRG. Exclusively used by CTRG Group 14 operators.
  • Sand: Desert sand/flat dark earth paint finish. Primarily used by Mediterranean NATO sharpshooters.


  • The MAR-10 is based on the real-world "Bad News" rifle designed by Noreen Firearms, an outdoor/sporting goods company based in Montana, U.S.A.
    • It is also fitted with a custom-designed stock, and what appears to be a front handguard inspired by the War Sport "LVOA" rifle, complete with a Top Hat compensator.
  • Unlike most other sniper rifles and DMRs, the MAR-10 is only capable of semi-automatic fire.
