Did you have the realistic Mattel M-16? That was a lot of fun! And a cap-firing tommy gun?
We had tommy guns, silver colored plastic hand grenades, felxible plastic bayonets on rifles and a Johnny Reb cannon for artillery.
Caps cost money, and we would pool our money and buy a box of rolls and did we have fun. Not everyone had the cap firing guns. Those that didn’t provided their own sound efforts.
We were on the honor system, becasue this was before paintguns.
