RE: Bushnell, Simmons or Redhead (bass pro shop brand)
Im not sold on the 50mm yet...the gun is a TC encore so I have plenty of rise in the comb as well as barrel clearance. I have a Nikon on another gun and I do like it....
As for using a fixed optic (as earlier suggested) Im not intrested in going that route. I have been in more then one situation where an adjustable optic makes life nice.
