History
Mk 46 Mod 0 This is a variant of the special purpose weapon adopted by USSOCOM. The program, which led to both the Mk 46 and Mk 48, was headed by the US Naval Special Warfare Command (NAVSPECWAR). Like the SPW, the carrying handle, magazine insertion well, and vehicle mounting lugs have been removed to save weight. However, the Mk 46 retains the standard M249 plastic buttstock instead of the collapsible buttstock used on the SPW. The Picatinny rail forearm also differs slightly from the SPW. The Mk 46 has the option of using the lighter SPW barrel or a thicker, fluted barrel of the same length.
Singleplayer/Spec-Ops
It appears with a Foregrip in the mission "Dust to Dust" being used by Yuri. Its first and only usable appearance, however, is in "Bag and Drag", where it can be found in a GIGN armoury, and is also carried by friendly NPCs.

The MK46 is available in a default class with both a grip and a RDS but unlocked for Create-a-Class at level 54. It is also mounted on the Assault Drone point streak with a unique 50-round belt. It is a relatively versatile Machine Gun, having moderate-high power, medium recoil, good range and a high rate of fire.

Description
|
Icon
|
|
Kick
|
Kick Reduces recoil by 20%, allowing for steadier full-auto and faster recovery from shots. |
 |
|
Impact
|
Impact grants maximized penetration for any weapon. This is especially powerful on Assault Rifles and SMGs, as LMGs already have strong penetration, and Sniper Rifles are difficult to use for intentional walling shots. |
 |
|
Attachment
|
Allows the use of 2 Attachments. It is a solid all-around Proficiency, useful in many situations. This Proficiency is also notably useful for stealth builds, as it allows you to use a Silencer alongside any other Attachment. The Attachment Proficiency is also helpful if you are still getting comfortable with iron sights, as it allows you to take and optical Attachment and a second utility Attachment. |
 |
|
Focus
|
Reduces visual recoil by 50% when you are hit. Focus is very effective for SMGs and Shotguns. It is also helpful for ARs, as it can keep your shots on target when you enter a heads-up one-on-one firefight. |
 |
|
Speed
|
Improves movement speed by 10%, or one step up on the mobility scale. Speed is an important upgrade for LMGs and Riots Shields. It is less critical for Sniper Rifles, excepting the Barret and AS50, which are heavier and slower than other Sniper Rifles. |
 |
|
Stability
|
Reduces idle sway by 25%. Consider this to be an 'automatic' Breath for long-range combat. It is most useful on LMGs, as they need the enhanced accuracy for long-range shots, though ARs also benefit from it. |
