The MX is a 6.5 mm assault rifle used by NATO forces and in limited numbers with CTRG operators in ArmA 3.


The MX is a selective-fire assault rifle chambered to fire the caseless 6.5×39 mm NATO round. It is the baseline assault rifle model upon which all other MX variants are based on.

It loads from 30 round double-stack STANAG magazines and can attain a fire rate of up to 625 rounds per minute, with a muzzle velocity of 800 m/s. The MX supports being fitted with accessories on all three rails; top, side, and underbarrel, while also being able to mount attachments onto its muzzle.

Largely constructed out of polymer, the MX is a lightweight weapon that is the standard issue service rifle of both Mediterranean and Pacific NATO forces. Compared to traditional 5.56 mm cased ammunition then-used by Western militaries, the caseless 6.5 mm round that it fires has increased stopping power while decreasing the weapon's weight at the same time.

In terms of performance, the MX has the best accuracy of all the assault rifle models (aside from the SPAR family) and easily outmatches both of its CSAT counterparts at any range. This enables the operator to lay down a hail of precision fire at distances of up to 400-600 metres. Despite being a conventionally designed rifle with a longer barrel, the MX is also faster to reload and takes one whole less second to rearm as opposed to its bullpup counterparts.

Its main downsides are its mediocre rate of fire which pales in comparison to the Katiba used by Mediterranean CSAT forces, and its slightly higher recoil while firing on full auto. Though its recoil is somewhat compensated by its good accuracy, the MX is still an overall more difficult weapon to handle.
