I wanted to buy a Fastfire III and still be able to use my factory bead. I ended up buying the Fastfire III and the Speedbead separate.
My question is will the Fastfire III metal protector work with the Speedbead mount? I am shooting a Benelli SBE II.
I think I read on this site a while ago that it will fit, but may obscure your vision a bit more on both eyes open shooting. I am buying a speedbead for my Maxus btw.
