Firecap

Firecap

Many semi automatic weapons have something known as a firecap. A true semi-auto weapon can fire as fast as you can pull the trigger, such as the M14 EBR or the M1911. Others, however, such as the M1 Garand or Modern Warfare 2's Desert Eagle cannot. They instead have a preset limit on the rate of fire.

On the 360 and PS3 versions of the past three Call of Duty games, there is a limit of aproximatly 1800 RPM for semi-auto weapons, although no human can fire 30 bullets per second. The Garand has a max limit of only 444 RPM, and Modern Warfare 2's Desert Eagle is currently unclocked, but is estimated at about 100 rounds per minute.
