.223: Bigger And Badder

Tom's Hardware's Biggest CPU Shoot-Out, Ever
By
.223: Bigger And Badder

The ArmaLite model 15 is one of the most easily recognizable rifles out there—largely due to the militarized version, the M16, used by the United States (and a number of other countries). The “civilian” AR-15 shoots the same .223 cartridge as the Ruger Mini-14 on the previous page. With a muzzle velocity of 3,200 feet per second, both guns are able to do some serious damage to the Opteron’s heatspreader, as we’ll see on the next page. 

The version of the gun being shot here is a California-legal model, with a standard upper receiver and lower receiver with a fixed 10-round magazine.
