RE: BOSS or no BOSS
they remind me of the old " dial a duck" chokes used on shotguns.....they work....yes they do.....but their gains (in my opinion) don' t outweigh the loss of barrel length, loss of aesthetics, extra muzzle blast directed back, extra weight, loss of resale value, ............They are a great marketing device and that' s about the end of their value.....
