MW2 M21 with silencer and heart rate sensor

The MW2 M21 with silencer and heart rate sensor will replace your regular G3SG1 rapid fire sniper rifle. For the first time, the model appeared in one of the first mw2 missions, after which it became an indispensable tool for silent shooting of opponents.
The heartbeat sensor is set for beauty, that is, it does not show enemies (sorry, but this is already in: D). The rifle is optimized for old PCs, and for all versions of counter strike source.
