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 accepts accessories on all three of its rails; top, side, and underbarrel, and can have attachments mounted onto its muzzle.


Ready and waiting.

Performance-wise, 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.

  • 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.
