Thanks for the replys. I had looked for the wiegland rail but could not make up my mind that it was the thing. I have ordered an ultra-dot 30 with 4 moa and I use Alaska Arms QD for other scopes so they are on order as well. I appreciate anyone who gave it a thought. I'd think some entrepreneur with a machine shop could make a first rate QD that would accept Trijicon rmr etc. There must be an alignment issue, strength or something. I know I'm not the only person wondering about it.
Some Rugers come with holes tapped on the integral bases. Should be pretty easy to have that done and then mount something like an Aimpoint Micro H2. I’d not depend on something like the Burris adapter, which works pretty well on lighter stuff.
Here is what I have done with my M77's. Using my worse than "Kyber Pass" skills and crude tools, I made small Pic bases for the rear bridge and attached by drilling 2 each #8-40 Torx screws. They'll hold any sight that single point attaches to a pic or Weaver base. My bases are only .175" above the Ruger integral base so it's no problem using Ruger factory iron sights with the red dot removed. Just in case I want to mount a scope on the rifle with Ruger factory rings, I epoxy bedded the mini bases, so with 2 screws they go back on to zero. I have to warn you, the blued Ruger M77 receivers are very hard. The stainless receivers are harder than the blued ones to drill and top. But once done, it is really a nice set up. RJ
