WHY? This is very close to what I would tell my kids when they were growing up, Because I said so! But to be honest its just that now at my age, the house is paid for, both cars and truck paid for, and I have already given more money to 5 kids than I should have. And in other words I'm spending their inheritance. I have been bump firing many years and its just a gagget that I don't need, but one I want. Also a plus is when I let my grandson shoot and see that big grin on his face that in its self is worth all the money in the world. Still considering the one for the AR platform..
