Most Missile launchers today are made from fiberglass. Even if the missile has a reverse plate made of metal, most of it is lightweight composites! A M-2 is 100% good old fashion American Steel. It weighs 84 Lbs UNLOADED! 50 Lbs for the gun, another 34 pounds for the barrel. Add 100 rounds of ammo about 12lbs....plus the recoil.....whereas most Missile launchers have close to no recoil.....I'm for Roadblock!
