What's with all the hate on the Desert Eagle? Sure the .50 cal AE version is totally pointless as a sidearm, but the gun comes in like two other flavors (.44 magnum and .357 magnum).
Worst firearm in modern history: The M16/M4 and it's variants (not including the HK M416/417). Probably caused the deaths of more Americans than any firearm the enemy (if your in the US) ever used. Indirectly of course, but a jammed gun might as well be a bullet to the face.
And i'm also a little confused as to the hate on the XM8. The thing beat out all the other rifles in the US trials. That is to say, it beat the FN SCAR, Colt M4, and HK M416. Personally, I'd rather have a rifle that jams once every 10,000 rounds that one that jams ever time it see a speck of dirt or sand. (unless the issue is the NATO 5.56mm round, which is shit.)
