The public range benefit is huge. I like the idea of having it not attached to the barrel. I may have to play with that.
I have surveyed a non-modified bayonet. It would not be hard to arrange a bench top mount for it without having to modify the unit.
The ease of setup at the range is the #1 reason I made the switch from my pain in the butt Oehler 35P. Loved the MSpeed so much I sold the Oehler. I can adjust the MSpeed without ever encroaching the firing line or needing a cease-fire..
