The Velko R4 5.56 mm assault rifle.

The Velko R4 is a 5.56 mm assault rifle used by UNA peacekeepers and in limited numbers with North African CSAT crewmen in ArmA 3. It was added with the release of the Western Sahara DLC.

The Velko R4 is a selective-fire assault rifle chambered to fire the 5.56×45 mm NATO cartridge.

It loads from either 35-round box magazines or 50-round extended magazines. It has a muzzle velocity of 925 m/s, and can attain a rate of fire that ranges between 600 (semi) up to approximately ~ 675 (full auto) rounds per minute.

The Velko R4 allows for optical sights to be fitted onto its top rail and can also mount a sound suppressor. However, because it utilises an integral folding bipod, it does not require a separate bipod to be mounted. Additionally, it lacks a side rail and cannot be customised with flashlights or laser pointers.

The Velko R4 supports only two types of magazines. They do not have alternate camouflage options.

It should be noted that none of its magazines are compatible with other 5.56 mm platforms. Both are restricted to only the Velko R4 and cannot be fed into any other 5.56 mm weapon:

5.56 mm 35rnd Mag


Standard 35-round magazine loaded with 5.56 mm ball ammunition. It has a weight of 9 "mass" units.

Only the last four rounds of the magazine consist of visible tracers.

5.56 mm 50rnd Mag


Extended capacity 50-round magazine. It is heavier and weighs a total of 14 "mass" instead.

Aside from its increased capacity/weight, it remains identical to regular 35-rounder magazines.


  • Western Sahara's Velko R4 is directly modelled after the South African-made "Vektor R4" assault rifle.
  • Although it is not utilised by the SFIA, North African CSAT crewmen are uniquely equipped with the Velko R4 (no other units are issued the rifle).
  • Following Update 1.02's release, the Velko R4's muzzle velocity was slightly reduced from its initial 950 m/s to its current 925 m/s.
The information below details unused, pre-release or removed content.
  • Curiously, there is an unused text string within the DLC's files that references a so-called "Velko R5 GL" variant (String name: STR_LXWS_VEKTOR_GL).
    • Based on its suffix, it can be assumed that it would be for a Velko derivative that is either equipped with an underbarrel grenade launcher or rifle grenade adapter. However, no actual config entry or a model exists for this (supposedly) unused variant.
