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


The MX 3GL is simply a modified version of the baseline MX variant that has an underbarrel grenade launcher attached. Like its parent model, the GL variant fires caseless 6.5×39 mm NATO ammunition where as the grenade launcher fires 40 mm grenades.

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 its top and side rails, while also being able to mount attachments onto its muzzle. The underbarrel grenade launcher has a quadrant sight with a red dot for the operator to aim with, and can be zeroed up to a maximum range of 400 m.

The MX 3GL shares the same strengths (and flaws) of its baseline model; the sole difference with this variant is its underbarrel-mounted 3GL grenade launcher. The 3GL is unique for being able to load not just one but up to three-round grenade "magazines" that can be fired in quick succession. Combined with its use of a red dot quadrant sight and weighing exactly the same as both of its CSAT counterparts, this undisputedly makes the 3GL the best underbarrel grenade launcher out of them all.
