The lights are on
Type 95: The Type 95 is unlocked at Level 32 in Call of Duty: Modern Warfare 3's multiplayer. It is a three-round burst weapon and has a high rate of fire per burst. The Type 95's high damage and fast rate of fire lead to one-burst kills quite often, making it versatile in almost all situations. The Type 95 can kill in only two bullets within range, but suffers from high damage drop at range, so at extreme ranges it may take up to five bullets (two bursts with no more than one bullet missed) to kill. It has less hipfire accuracy compared to most assault rifles due to the recent patch that reduced the Type 95's overall effectiveness.
M4A1: The M4A1 can be modified with an M203, Red Dot Sight, supressor, or ACOG scope after having completed the respective marksman challenges. The M4A1 is an excellent weapon in the right hands, with moderate damage and fairly low recoil. However, the M4A1 has fast, large idle sway making it more difficult to aim properly at long range. The M4A1 shares ammunition with the M16A4 and the G36C. The M4A1 Carbine is one of the most commonly used weapons in online multiplayer on all platforms, due to its low unlock level and good stats.
As stated above, the M4A1 is not particularly effective at long range due to its large idle sway. However, the M4A1 is ideal in both close quarters and mid-range combat due to its high rate of fire, decent hipfire accuracy, and low recoil. Steady Aim also makes the M4A1 even better in close quarters. Stopping Power improves further upon the weapon's versatility, making it deadly at all ranges, and Bandolier aids the player's longevity in combat by offering a large supply of ammunition.
The weapon's low damage output is mitigated by its high rate of fire and very low recoil, allowing for accurate automatic fire at both short and medium ranges and even burst fire at longer ranges. Whether equipped with optics or a grenade launcher for assault or a suppressor for stealth, the M4A1 remains effective in almost all combat situations.
MK14: The MK14 is unlocked at Level 60 in Call of Duty: Modern Warfare 3's multiplayer. It has a low capped rate of fire, but it has high power, as it kills with two hits to the chest or one headshot at close range, and 3 shots to the body at long range. It will also kill with 2 shots at range if one is a headshot. Considering that this rifle has one of the longest effective range of all assault rifles most of the time it should only take 2 shots to drop a target. Its recoil is very controllable compared to the M14 from Call of Duty 4: Modern Warfare, especially when combined with the Kick proficiency.
Due to its high damage and hipfire accuracy, it is often favored in Hardcore game modes as a makeshift sniper rifle if using the Attachments proficiency and equipping an ACOG Scope and Suppressor, as the silencer's range penalty is mitigated by the fact that it is still a one hit kill at all ranges in Hardcore mode, unless the target has a Ballistic Vest, however, a headshot will kill anybody regardless of whether or not the target has a Ballistic Vest instantly on Hardcore.
Rapid Fire has a unique effect on the MK14; because the weapon is semi-automatic, Rapid Fire simply raises the fire rate cap, allowing for marginally a faster fire rate. This can be useful in close quarters and when facing many enemies that need to be quickly dispatched; however, for most situations, it's not necessary.
Another unique part of this weapon is the Shotgun attachment. Equipping the Shotgun dramatically increases visual recoil when firing the rifle. The sights kick back heavily, making it more difficult to accurately place follow up shots, except with the Thermal Scope.
O.K. this is my first guide and is in Construction and is not complete, I am aiming to get this complete as soon as I can, I will usually post 1 or 2 weapons and there facts a day also, if you edit this guide only edit or add weapons. Also I admit some of this stuff is copied from Wiki but is edited.
