« The Gepard GM6 Lynx is a semi-automatic anti-material rifle using Russian 12.7x108 mm ammo. Its purpose is to stop or disable targets such as light armored vehicles, light shelters and helicopters from 600–800 m range. Due to its weight and portability, it is good for parachute, airmobile and territorial troops. The barrel recoil technology brings the recoil of the GM6 below the recoil of other rifles in the same category. The weapon is highly accurate and effective up to a range of 1500 m.

The GM6 Lynx 12.7 mm sniper rifle.

The GM6 Lynx is a 12.7 mm bullpup anti-materiel sniper rifle used by CSAT and AAF snipers in ArmA 3.

Overview[]

The GM6 Lynx is a semi-automatic, long-recoil operated anti-materiel rifle that is chambered to fire the 12.7×108 mm round.

It loads from 5-round box magazines, and can attain a rate of fire of up to 150 rounds per minute[CfgWp 6][Formula 1] with a muzzle velocity of 820 m/s.[CfgMa 2] It only has a top rail for mounting optical sights[CfgWp 7] and cannot be fitted with any other kind of accessory or muzzle attachment. However, it does have an integral folding bipod that is fixed onto the centre of the barrel.[CfgWp 8]

Unlike its NATO counterpart, the GM6 has the unique ability to load and fire Armour Piercing Discarding Sabot (APDS) ammunition. Aside from being able to instantly kill soldiers wearing heavy plate carriers in one hit regardless of distance, these 12.7 mm APDS rounds can penetrate the armour of MRAPs and other lightly-armoured ground vehicles. Even heavier vehicles with exposed components such as optics or uncovered wheels can have some of their weapon systems be disabled with this ammunition should they be struck in the right locations.

While it is significantly less accurate than the M320 LRR when it comes to long range engagements[CfgWp 9], the GM6 compensates by firing the more hard-hitting 12.7 mm round that not only inflicts ~ 37% more damage[CfgAm 1], but also has slightly better penetration against armoured targets.[CfgAm 2]

However, it should be noted that the GM6 is rather bulky to carry and being a sniper rifle, is naturally ill-suited for use in close quarters combat.[CfgWp 4] Its magazines are also slightly heavier to carry while containing two less rounds in comparison to the M320's seven.[CfgMa 3]

Ironsights[]

Arma3-gm6-ironsight-overview

The GM6 Lynx's ironsights can be zeroed starting at a minimum of 100 metres up to a maximum of 600 metres (100, 200, 300, 400, 500, 600).[CfgWp 10] It uses a default zeroing of 200 metres.[CfgWp 11] Neither the front nor rear sights are illuminated.

If an optical sight with a zeroing limit greater than 600 metres is fitted onto the top rail (e.g. LRPS), the GM6 will allow for an absolute maximum zeroing of 2,200 metres.[CfgWp 12]

Camouflage[]

  • Grey: Standard matte grey paint scheme. Used by AAF snipers.
  • Camo: Arid Hexacam camouflage pattern. Used by Mediterranean CSAT snipers.
  • Green Hex: Tropical Hexacam camouflage pattern. Used by Pacific CSAT snipers.


Western Sahara Creator DLC only

NOTE: The following camouflage schemes will only be available if the third party-developed Western Sahara Creator DLC is activated.

  • Snake: Snakeskin-style spraypaint pattern applied over a grey finish.

The GM6 can be loaded with two types of magazines.[CfgWp 13] Both magazines share the same weight of 16[CfgMa 5][CfgMa 6] "mass" units:

12.7 mm 5Rnd Mag[]

Arma3-ammunition-5rndgm6ball

Standard-issue box magazine loaded with five rounds worth of 12.7 mm Russian ball ammunition.[CfgMa 7]

None of the rounds fired will emit visible tracers.

12.7 mm 5Rnd APDS Mag[]

Arma3-ammunition-5rndgm6apds

Specialised 5-rounder box magazine loaded with armour-piercing 12.7 mm APDS ammunition.[CfgMa 8] Intended for use against lightly-armoured ground vehicles and exposed components on armoured fighting vehicles.

Rounds fired from this magazine specifically have a greater muzzle velocity of 1,060 m/s[CfgMa 4] and can penetrate up to ~ 57 millimetres of armour plating.[CfgAm 8][Formula 3]

Trivia[]

  • The GM6 Lynx is based on its real-world counterpart of the same name designed by Hungary-based firearms company SERO Engineering Ltd.[1]
  • Initially, the GM6 was only available in a grey paint finish. The Bootcamp Update added an alternate variant with the Arid Hexacam camouflage scheme[2], while the Green Hex variant would not be included until the Apex expansion was released.[3]
  • The GM6 Lynx was not originally available as part of the Alpha's assets at launch and was only added into the game after Game Update 0.60 (alongside the introduction of snipers for both NATO and CSAT).[4]
  • At launch, the GM6 only had a weight of 140 "mass". This was greatly increased to its current 480 "mass" after Game Update 1.38's release (representing an approximate ~ 242% increase in weight).[5]
  • Prior to Game Update 1.52, the GM6's charging handle was not animated. The patch also corrected the bolt's animation upon firing the magazine's last round.[6]
  • It is one of the few weapons in ArmA 3 that is directly referred to by its real-world manufacturer name. This is because representatives from SERO provided Bohemia Interactive's developers with CAD data for the GM6, a chance to record audio samples, to test fire the weapon with live ammunition, and authorisation to use the GM6 as an in-game asset.[7]
The information below details unused, pre-release or removed content.
  • Arma3-gm6-04

    IR Laser Pointer fitted onto the GM6's (disabled) side rail.

    The GM6's model has an unused proxy for mounting side rail accessories.
    • Because the weapon is not configured to do so by default, however, the user cannot fit laser sights or flashlights onto the weapon despite side rails being depicted on the model itself.

Formulae

  1. 60 / reloadTime = 60 / 0.4
  2. initSpeed * caliber * 15 / 1000 = 820 * 2.8 * 15 / 1000
  3. 3.0 3.1 initSpeed * caliber * 15 / 1000 = 1060 * 3.6 * 15 / 1000

Notes[]

  1. 1.0 1.1 Damage will be reduced if the projectile's velocity drops below this value.
