The SC-IS Sniper Rifle has an internal suppressor, powerful damage output, and extensive range, making it one of the most powerful weapons in the Fourth Echelon line of prototype weapons, as well as being one of the most powerful sniper rifles used by Fourth Echelon during the Blacklist Attacks in 2012. Developed by Charlie Cole, the SC-IS SR is built uniquely and ideally for long distance sniping with a minimized chance of being detected due to the suppressor. The SC-IS SR's strongest offensive features are also its best answer to counter enemy snipers.
