Mk20

«

The Mk20 is a gas-operated rotating bolt, selective-fire weapon, which was designed as a highly moddable weapon. Its design and front ejection system allows true ambidextrous use. Two other variants of Mk20 exist. The Mk20C comes with a shorter barrel suitable for close combat and the Mk20 EGLM comes with an enhanced grenade launching module. Field Manual

The Mk20 is a 5.56 mm bullpup assault rifle used by the AAF, Altian government Loyalists and in limited numbers with FIA guerillas in ArmA 3.

Overview

The Mk20 is a gas operated, selective-fire bullpup assault rifle that is chambered to fire the 5.56×45 mm NATO round.

It loads from 30-round STANAG magazines, and can attain a rate of fire of up to ~ 857 rounds per minute with a muzzle velocity of 900 m/s. The top and side rails support being mounted with accessories while the muzzle can also be fitted with attachments.

Mk20 fitted with an MRCO.

The Mk20 serves as the standard issue service weapon of the AAF, and is also used by FIA marksmen as a stand-in for heavier battle rifles. Similar to the TRG-21 used by the FIA, it is also a bullpup rifle that that is ideal for use in both short-medium ranged firefights due to its compact layout.

Compared to the TRG-21, the Mk20's recoil is easier to manage (for a 5.56 mm weapon) and has a greater rate of fire of 857 rounds per minute versus the TRG's 750. As with the TRG-21 however, the Mk20's usage of 5.56 mm ammunition results in poorer performance over long ranges compared to assault rifles chambered in larger calibres such as the MX or AK-12.

As a result, the Mk20's higher muzzle velocity does little to compensate for its lower damage. The only upsides are that the weapon and its magazines are lighter to carry, though it also means that the user needs to expend more rounds per target if they happen to be wearing ballistic-resistant vests.

The Mk20 EGLM is a modified version of the baseline Mk20 rifle that has an underbarrel grenade launcher attached to it.

As with its parent weapon, it is also chambered to fire the same 5.56×45 mm NATO round while the grenade launcher can launch 40 mm grenades, ranging from harmless smoke/flare shells to high-explosive (HE) rounds.

It loads from the same 30-round STANAG magazines and is virtually identical aside from having an increased inertia penalty on the operator due to the addition of the grenade launcher.

The EGLM uses a red dot quadrant sight that can be zeroed up to a maximum distance of 400 metres.

All variants of the Mk20 support being fed with 30-round STANAG magazines, interchangeable with any other weapon chambered for the 5.56 mm NATO round. They are all available in either a Black or Sand finish, and have identical weights of 8 "mass" apiece:

5.56 mm 30rnd Reload Tracer (Yellow) Mag

Basic 30-round 5.56 mm STANAG magazine. The last four rounds of the magazine always consist of yellow tracers.

5.56 mm 30rnd Reload Tracer (Red) Mag

Identical to the baseline STANAG, but the last four rounds consist of red tracers instead.

5.56 mm 30rnd Reload Tracer (Green) Mag

Identical to the baseline STANAG, but the last four rounds consist of green tracers instead.

5.56 mm 30rnd Tracer (Yellow) Mag

Contains 30 rounds worth of visible yellow tracer ammunition. Identical in all other aspects to regular STANAG magazines.

5.56 mm 30rnd Tracer (Red) Mag

Consists purely of visible red tracers. Identical to the other full tracer STANAG magazines.

5.56 mm 30rnd Tracer (Green) Mag

Consists purely of visible green tracers. Identical to the other full tracer STANAG magazines.

Trivia

• The Mk20 and its sub-variants are based on the real-world "F2000" bullpup assault rifle designed by FN Herstal of Belgium.
  • More specifically it is based on the "Tactical TR" model of the F2000, and it uses a "Tri-Rail" foregrip that was then-designed by Monolith Arms (now owned by Magpul Industries).
  • The Mk20's designation should not be confused with the real-life "MK20 SSR", a designated marksman rifle that is also designed by FN Herstal.
• The EGLM on the other hand, is based on FN Herstal's "GL1" grenade launcher module that was designed specifically for use on the F2000 family of bullpups.
• Screenshots released during the pre-Alpha phase of ArmA 3's development indicated that the Mk20 was originally meant to be a NATO weapon. By the time of the Alpha and Beta's release however, it was eventually replaced by the MX.
