I was looking for a sight that would clamp to the top rail on its own...................
I realy don't want all that GI Joe black ramp stuff on top of my gun............it is only for 25 yards, testing out reloads,since my eyes with Bi-focals and the gun and target are not working like they did in the past.

I looked at Bushnell first strike but it got a lot of bad replies and the Star is China ...junk.

Just hate to take the rear sight off for the new unit. S&W 686

Thanks for any help.
