How the heck did you get your hands on a BAR?
It was back in the '90s...a local gun shop had number of full auto weapons that you could rent, to shoot on their range. There are a growing number of businesses in Las Vegas that do that today.
Anyway, they had (among other things) an Uzi, an MP5, and a BAR available. Not a hard decision to make!
At that ancient time, there were several WWII era weapons we got to play with, like the flame thrower and 3.5" Bazooka. Great stuff for teenagers too young to vote or drink...............
