Sign in to edit

« The Mk22 Mod 0 pistol is a single-action semi-automatic pistol, with a 10-round magazine chambered for 9mm parabellum. It was commonly issued to Navy SEALs and tunnel rats in Vietnam. This pistol had a suppressor with a slide lock mechanism that further reduced the produced noise. The gun's purpose was to eliminate sentry dogs or guards without alarming targets.

The Mk22 Mod 0 is a 9 mm handgun used exclusively by MACV-SOG forces in ArmA 3. It was added with the release of the S.O.G. Prairie Fire Creator DLC.

Overview[]

This section is a stub. You can help Armed Assault Wiki by expanding it.

The Mk22 Mod 0 is a semi-automatic handgun that is chambered to fire the 9x19 mm cartridge.

The Mk22 feeds exclusively from 14-round box magazines. It can attain a fire rate of up to 600 rounds per minute[CfgWp 7][Formula 1] and has a muzzle velocity of 280 m/s.[CfgWp 8]

A sound suppressor can be attached onto its muzzle (this same suppressor can also be shared with Model 10 revolvers).[CfgWp 9] However, it is not possible to mount an optical sight onto the Mk22, nor is it possible to wield it simultaneously alongside a flashlight/torch.

Ironsights[]

Arma3-sogpfmk22-ironsight-overview

The Mk22's ironsights are set to a fixed zeroing of 50 metres.[CfgWp 10] It is not possible to manually adjust this to a different setting.

Ammunition[]

Trivia[]

  • Prior to being fixed in Update 1.1, the Mk22's magazine description incorrectly stated that it contained 7.62×25 mm rounds as opposed to 9×19 mm (despite the fact that the magazine was properly configured to load 9 mm ball ammo).[1]

Formulae

  1. ↑ 60 / reloadTime = 60 / 0.1
  2. ↑ Magazine's initSpeed * Ammo's caliber * 15 / 1000 = 300 * 0.8 * 15 / 1000
  3. ↑ Weapon's initSpeed * Ammo's caliber * 15 / 1000 = 280 * 0.8 * 15 / 1000

Notes[]

  1. ↑ This muzzle velocity only applies to the magazine itself. The Mk22's weapon class has its own initSpeed value defined (280 m/s) that always takes precedence over the magazine's initSpeed value.
  2. ↑ This is the Mk22 Mod 0's actual muzzle velocity. The weapon class initSpeed value (280 m/s) takes precedence over the magazine initSpeed value (300 m/s).
  3. ↑ Damage will be reduced if the projectile's velocity drops below this value.
  4. ↑ This is the actual penetration depth of the Mk22 Mod 0's 9 mm ammunition. The weapon class initSpeed value (280 m/s) takes precedence over the magazine initSpeed value (300 m/s), affecting its penetration formula as a result.
