After working for three well known outlets. Absolutely not a prayer.
No profit whatsoever and the number of 'customers' who defy all sense of, well, sense, is breathtaking.
Plus, the amount of tales of, 'I shot a rabbit at 200m with a B2, guns are a tool, it's worth more than that second hand, its not rust, it's patina, a friend borrowed it and did that, etc etc', does become boring after the umpteenth time in an hour.
A good tip to take into any gunshop is, your tale has been told before. And laughed at.
