Sorry for the first two blurry photos. I was in a hurry to leave my main blaster storage and I only discovered a better setting for the last photo.
Theres a couple of subtle cosmetic changes on the Rampage. First, the Rampage as a whole blaster looks smaller then the Raider, or is it just me? The handle of the and stock addition area are a darker gray then the Raider. The area below the magwell on the Rampage has gray, while the same area on the Raider does not. The Rampage handle has a darker gray area, while the Raider’s is lighter. Finally, the Rampage’s colors are accented with white and gray.
