Metal Eater

The Metal Eater (メタルイーター) is the nickname given to a series of powerful sniper rifles used in the Toaru Majutsu no Index universe. The most famous of course is the Metal Eater MX, one of the standard weapons that are used by the Sisters along with the Toy Soldier.

Specifications and capabilities
The Metal Eater MX (鋼鉄破り(メタルイーターMX)) is actually a Barret M82A1 anti-tank rifle. In the Toaru Majutsu no Index universe it has the reputation of blowing up a tank from 2000 meters away during the Gulf War. The Barret M82A1 that are used by the Sisters however are prototype models that allows the use of the full-auto feature, allowing for rapid fire usage. The feature was originally removed for the mass production as the recoil was excessively powerful, which can smash a shoddy helment into pieces.

The Sisters who use the rifle have no problem with it as they have received the necessary information using Testament on how to counteract and ward of the powerful recoil. The rifle had a length of 80 centimeters, uses .50 caliber anti-tank bullets, and can fire it at speeds of 1200 kilometers per hour.

Specifications and capabilities
The Metal Eater M5 (メタルイーターM5) is an anti-tank semi-automatic rifle that was used by Academy City in World War III. It was originally the MX, only with modifications done to the handle and scope, and a water cooler was installed to it. It is capable of causing some damage to a Powered Suit. It still retains the massive recoil that was present in the Metal Eater MX.
