The M240 has mild recoil for a light machine gun, but enough to throw off aim at medium to long distances if firing full-auto. Because of this, the Grip is recommended. The weapon has slightly obstructive iron sights that are similar to that of the M16A4, the third fastest reload time for an LMG, low damage, and an extremely high rate of fire. Scavenger is a good choice as the weapon expends ammunition quickly, however as an LMG two one-hundred round belts is sufficient for most occasions. If used with both a Grip and Red Dot Sight, the M240 can be very effective at all ranges if burst firing is used effectively. The lack of damage drop off means it is most effective at long range, where it will still down a player in three shots with Stopping Power, or four without it in normal circumstances.
Because of the lack of damage drop off, using a silencer - with or without Stopping Power - is extremely ill-advised, as the Silencer is subject to a glitch and will not conceal the player's position on the radar, all the while requiring one more bullet to kill at all ranges. This does not render the silencer completely useless though, as it removes the muzzle flash when firing.
The M240 has low damage for an LMG, balanced with its extremely high rate of fire. The M240 excels greatly in Hardcore, where it delivers one-hit kills at any range at a very high rate of fire with some mild, easily controllable recoil. The high rate of fire and high capacity makes this weapon a premier choice for bullet penetration kills. The M240 suffers from very high muzzle flash when fired in full-auto. The Holographic Sight is a solution to both problems; the sight is elevated, therefore the player will see a notably lower amount of flash.
Stopping Power does not have a significant effect on the M240 due to the high fire rate, making other Tier 2 perks more viable options, such as Hardline for quicker killstreaks and Lightweight for getting to positions quicker and faster recovery after sprinting. The M240 is highly suited to providing a constant stream of suppressing/covering fire. Sleight of Hand Pro is recommended due to the longer sight raise time without the perk. It also performs quite well as an overwatch weapon with any optic plus a Grip with Bling, having moderate, mostly visual recoil that can down a target surprisingly fast, with or without Stopping Power.
When picked up in the campaign in the Wii version of the game, sometimes it will spawn with no iron sights at all, making aiming difficult. Despite this, it will still be aimed as if it had a optic on it, making it nearly impossible to shoot it at farther ranges.
