The primary reason I think you don't see more is 1) weight, 2)cost, 3) bolt guns are usually more accurate. I have a BAR and it is a very good rifle but it is heavy and I don't ever plan on more than 1 shot. I don't even work the bolt on my gun after the shot most of the time. Not bragging, I just don't take risky shots.
