Why does a suppressor need a solid shoulder seat well but the adapter needs no such shoulder?
According to my interpretation of our discussion here, an adapter does need a shoulder as well. However, it can be less than a direct mount situation requires when permanently, or semi-permanently affixed. That way there's less wear on the small shoulder than there would be from repeated mounting. The wear would be on the ample adapter shoulder, not the slight shoulder on the barrel. Subsequently less risk of getting askew and going to hell with a potential baffle strike or cockeyed inaccuracy potential and other bad chit nobody wants to experience.... Essentially, the shoulder for the adapter, and/or the suppressor is necessary to ensure absolute proper alignment with the bore. Don't shoot your supressor.
Goodness, I hope that's right, or I'll, PUN alert, hear about it.
