Remington Gyro-Sniper Rifle

Remington Gryo-Sniper Rifle is gyro sniper rifle. A development of the gyro-rocket system initially proposed by Hughes and Militech in 2008, the Remington Gyro-Sniper fires a rocket-propelled, gyrostabilized shell. Through the use of advanced sensor technology, the shell homes in on the weapon's laser designator. The designator's integral range-finding computer determines such factors as wind speed/direction, distance to target, etc., then vectors the shell toward the intended target. lowlite and infrared capabilities are built in. The incredible stopping power (and long range) of the Gyro has earned it the nickname "Zeus' lightning" among police and Max-Tac snipers. Its ammunition is quite expensive: 400eb for a case of 50 shells.
