The best gun is the AK-47 with the red dot sight.
The red dot sight in MW3 is not available as a customization option like in MW2. In MW3, you can use the available optical attachments such as the holographic sight or the red dot sight provided by default with certain weapons.
Red dot, grenade Launcher, FMJ, or an ACOG sight.
Instead of a single dot, it has a small circle with crosshairs. It's generally a better aim.
the wa2000 thermal scope and heartbeat sensor with a raffica red dot sight fmj
holographic sight is practically the red dot sight but bigger. personally i like the holographic sight alot better. The RDS can be a little off on some guns (FAL), while the HS isn't.
Modern Warfare 2 is going to be in this period of time. That is why it is called MODERN Warfare 2.Lolz. Indeed. Too bad CoD:WaW was such a disappointment going back to old weapons and WW2 and all that crap. Can't wait for MW2 and that awesummm new Red Dot Sight.-xKillingxCupidx
By my opinion... -If you like to be cheap, put on a grenade launcher. -If you want to be more tactical, put on a red dot sight. -If you want to be a ninja, put on a silencer.
just get kills with the gun, then when you unlock attatchment like the red dot sight, getting kills with that attachment on will unlock further thing like so: grenade launcher - underslung shotgun silencer - heartbeat sensor red dot sight - holographic sight FMJ - extended mags ACOG scope - thermal scope
Once you reach level 25, you can customize the red dot sight and the reflex sight by going to your primary weapon with a sight equipped, then to Reticule or Reticule Color, which customize the shape of the dot and the color respectively. Once you level up a bit more, you can change the lens color as wel. Your sight could be an arrow like a classic Modern Warfare ACOG Scope, a smiley face, a yin-yang symbol, a star or even the Treyarch symbol!
