M-97 Viper/MEAMP Viper S Siphon

Description
The Viper is a rapid-fire rifle popular with military snipers who appreciated a long-range gun that could snap off multiple shots in a short period. Rosenkov Materials sold a considerable number of Vipers to the Initiative at a discount in return for undisclosed favors from Initiative founder Jien Garson.
