Have to wonder if that was a movie prop gun. Would have to be a stout chick to hoist a BAR up offhand like that.
Had to have been something like that. The actress fired it in that shot. I’m guessing that they used as a light a load as possible.
But then the real Bonnie Parker was diminutive and she used a BAR during one of the shootouts.
My dad, who went on the beach at D-Day+3, told me it amazed him that every time he needed a replacement GI that it was the smallest guy in the squad that wanted to carry their BAR. The little guy syndrome? He never knew of course, but it always mystified him. Never failed how they wanted to most fire power they could carry.
I recall reading years ago that Bonnie fired a BAR at a sheriff, split the tree he was behind or some such thing. Bonnie was said to like the power of the BAR.
