Whats the best gun for MW2?

The nerf gun. It shoot's orange darts and is almost never accurate. You can't get long shots with it sadly ): But it's good for close combat. Especially the vulcan heavy automatic blaster.

Well, i don't think theres is a "Best Gun" because they all have their own advantages, but a good class would be UMP45 Silenced with Marathon, StoppingPower and Ninja. Equipment claymore or C4 and stuns. But honestly experiment with different guns and perks until you find something your comfortable with. Good Luck!

m1a1 its good on fire rate or u wanna be juggernaut use the first lmg just hold rt or r2 when ever you see an enemy think of an no clip gun with infinet ammo no will get you thats cheap too bc they wont be able to hide suggest using steady aim as a perk or watever it is

wow..i cant believe no one has said tar-21 that **** murders i got my first 3 nukes with the silencer, perks scavenger pro, stoping power pro, ninja pro, secondary not really necesary if your using scavenger, but i would raffricas akimbo. kill streak nuke/ harrier,ac130,nuke non-nuke/ sentry gun.(its really underestimated but it can get you more kills then preatetor missle if put in the right place) harrier chopper gunner. marty down. painkiller is for *******

M16 w/Red Dot Sight or Holographic. Add a SPAS-12, Claymore, Scavenger Pro, Stopping Power, and Ninja and you have the world's best camping class. Edit: If you're a runner, the UMP45 seems to be everybody's favorite. The perks on that one are obvious, I'd hope.

The guns I find to be the most rewarding are the MP5 with FMJ, and the Scar-H with a silencer. Also Intervention with FMJ is good.

Seriously, ACR is the only way to go
