WSM400A1

The WSM400A1 Carbine is a fully automatic assault rifle with a shortened M203 grenade launcher, laser sight, and flashlight. Favored by Progressive Restoration units for close-quarters combat because of its compact size and firepower, this weapon has an effective range up to 150 meters.

The WSM400A1 is the third weapon you obtain in Shadow Complex. It appears to be based on the Colt M4A1, a real-world assault rifle/carbine.
