This has got me very interested. I used to be a much better shotgunner then I am now, I've fallen out of practice.
How is it that you can still see the red dot with the gun mounted incorrectly? I don't doubt you, but I've never used a red dot sight so I don't know. Is it that you can't see the bead with out your head mounted correctly, or that its always in the right spot?
And with the SBE, can you still use the inserts for stock fit?
