I can see the advantage of this suppressor in terms of stability in mounting, and perhaps balance of the whole thing, but I think it would not be as efficient as the entire length hung off the barrel. One key of max efficiency of a suppressor is permeability of the medium surrounding the bullet's path, and surface area would figure heavily into this. Yes, we have again as much volume in the structure behind the muzzle, but access to it is restricted to the I.D. of the outer tube, minus the O.D of the muzzle, sectioned at the muzzle, when this surface area is calculated. But it may be that the pressure is developed in the system quickly enough that my point may be negligible. Anybody know for sure?
