Another vehicle mounted airsoft support weapon that actually comes with a vehicle from Evike.com... "We built a 240 Bravo Polarstar Custom to work with our HMWVV. We do a lot customization to allow for a 7.62 size drum mag to function as the actual drum mag. The gun is powered by a large Scuba tank inside the HMWVV. Look for this weapon and the HMWVV at an event near you."
