Pictured below is the German MG42. The MG42 was one of the most feared small arms of World War II. It is still consider today to be one of the finest light machineguns ever made. The U.S. M60 is a copy of the MG42.
This marker includes:
Tippmann 98C w/ E-grip
Real Steel MG-42 Shell
The Real Action Paintball MG42 Machine Gun is newer, so it should be commonly available, both new and used.
