The BAR (Browning Automatic Rifle) has been around since like forever. I know it was in use during the during WW II - so the freakin thing has been battlefield tested.
I doubt that the commercial hunting BAR rifles are the same as their military predecessors, but Browning does have distinguished history in the area of automatic rifles.
I don't think there is a more widely used and widely respected automatic rifle then the BAR. So if I were you, I'd go slap that salesperson up side the head for making
such a moronic statement. I've owned a .308 Browning Lightweight Stalker (although I could never figure out what was so light about it) and the thing just worked and
worked and worked - never a misfeed, a misfire, or a stovepipe - an extremely reliable gun. How the newer Short Trac BAR rifles compare to the older BAR rifles, I'm
not certain, but if it has "Browning BAR" as part of its name then it's probably a pretty good rifle.
