The M320 LRR .408 sniper rifle.

The M320 LRR is a .408 sniper rifle used exclusively by NATO forces in ArmA 3.


The M320 LRR is a bolt-action sniper rifle that is chambered to fire the .408 Cheetah round.

It loads from 7-round box magazines and can attain a fire rate of up to 50 rounds per minute, with a muzzle velocity of 910 m/s. The M320 has a single top rail that can only accept optical sights. It has an integrated bipod located just to the front of the barrel where the shroud is located.

The M320's .408 round can score 1-shot kills no matter the distance.

In terms of performance, the M320 completely outmatches every other sniper rifle and machine gun when it comes to both range and precision.

When paired with long range optics such as the LRPS, it is entirely possible to engage targets at distances of up to 2,200 metres with pinpoint accuracy; a feat that can be matched by very few vehicle-mounted heavy weapons and even less handheld firearms (other than the SPMG).

Compared to the 12.7 mm round fired by its CSAT counterpart, the M320's .408 Cheetah has better ballistics that can travel faster and further, though at the cost of some power loss at shorter ranges. However, because the M320 uses a bolt-action operation, it is somewhat difficult to re-engage targets quickly and causes it to have an extremely low base rate of fire.


  • Black: Matte black paint scheme. Used by NATO snipers based in the Eastern European theatre.
  • Camo: Spraypaint scheme designed to mimic NATO's MTP uniform camouflage. Used by Mediterranean NATO snipers.
  • Tropic: Tropical jungle camouflage. Used by Pacific NATO snipers.

The M320 only accepts one magazine type. It has a "mass" value of 14 units:

  • The M320 is based on the real-world "Intervention" series of sniper rifles designed by CheyTac LLC, an arms manufacturer based in South Carolina, U.S.A (more specifically, it is based on the "M200" variant).
    • Likewise, the characteristics of the .408 Cheetah's ballistics model is based on the real ".408 CheyTac" round used exclusively by the Intervention series. The real .408 CheyTac is notable for its very high accuracy at extreme ranges.
  • Despite being a bolt-action weapon, there is no animation for cycling the M320's bolt.
    • However, an unused animation (animation name: GestureFireLRR) complete with an accompanying soundset does exist in the game files. Because there is no native engine-level method for simulating bolt action animations however, these cannot be seen in-game without using scripts.
  • Initially, the M320 was only available in the default all-black paint finish. The Bootcamp Update would eventually include an alternate variant featuring the MTP camouflage scheme.
    • The Tropic variant would be the last to be added and was only included after the release of the Apex expansion pack.
The information below details unused, pre-release or removed content.
  • Suppressed M320 LRR, using a .338 suppressor as a placeholder.

    Oddly enough, the M320's model has an unused proxy point that would allow the model to mount a muzzle attachment.
    • However, because the M320 isn't configured to accept muzzle attachments, nor are there dedicated .408 suppressor models, the M320 cannot be suppressed without the use of a custom addon.
    • Additionally, the M320 doesn't have a dedicated soundset for firing with a suppressor and will therefore be completely quiet when fired (only the weapon's default sound shader tails will play).
