I see that the knurled piece actually slips down over the tip of the arrow, concealing the tip of the insert up inside.

What the heck is the purpose of that? Maybe the same principle as the old Beman external inserts - adding a little more structural integrity to the tip of the arrow?

Yeah, I'd agree - look for the Rocket Bunker Buster to come to a clearance aisle near you. Nobody is gonna buy those things... Then again, Matthews has been selling the same bowin different camo patterns and withdifferent (prettier)limbs/risersfor 10 years straight, raising the price every year, and there are still people lined up to get them. Bowhunters can be strange ducks, and if they market it right, anything is possible.
