Add some real teeth to your arsenal and rip through enemy lines as you arm your G.I. Joe or other 1/18 scale vehicles with my Mark II heavy armaments 50 caliber Browning machine gun and my intricately detailed mount and swivel. It is easy to put together and install with several points of articulation. Some minor retooling may be necessary to properly fit the parts and mount on the desired custom vehicle. Retooling with a rotary tool, pin vise or drill may be necessary. If the swivel loosens it may be tighten with a drop of super glue then moving the joints until there is enough friction between the moving parts.
