Overview
The M590 CQB Mariners, (or M590 CQB SE) is a special variant of the M590 CQB. It is considered to be the strongest variant of the M590, and it had the honor of being an easy 1-shot kill before its power was greatly reduced.

Features
Some players may have a difficult time differentiating this gun from the original M590 Mariners during combat. If you look carefully, you'll notice that it is even shorter than the original Mariners, making it the most compact M590 Variant. The Mariners CQB has even further increased damage and decreased spread from the original M590 CQB, which is highly noticeable, as the Mariners CQB can get one-shot kills from a distance about 8 feet greater than the original CQB. It can fire quickly, with plenty of damage, making it a lethal gun. However, most players may not be used to the much decreased recoil and weight.

Usage
Gameplay footage of this weapon shows that a player was actually able to take down almost all of his/her enemies from a single shell. However, this isn't always the case, as enemies might have already been damaged by other players to some degree. Rumor among players states various conflicting things about getting kills with this gun, including that enemies have to be damaged to get a one-shot kill, enemies do not have to be damaged to get a one-shot kill, and that enemies can be killed with 2 shots at medium range.

Trivia
