I want to mount a Docter Optic sight on my 500 Nitro Double. It has a rib but is not drilled and tapped for a scope. I would like a quick detach mount. What is the best way to mount it?

Have asked JJ Perodeau the same question about mounting a Trijicon RMR06 to my .303 double. No reply as yet as I imagine he's very busy.

Of note is that the ribs, as I look at them, are not wide enough for most rings/mounts even if you are able to mill a slot on each side to attach them to.

Please post if you find out from another gunsmith and I'll do the same when JJ gets back to me.

Regards

I called Merkel USA today. They had me send them images of my rifle and said they will try to figure something out.They said they could mill down the Rib but I didn't want to do it that way. I'll post when they get back to me.

You could do it the heym way. Where they mill the sides of the rib and a small hole in the top. Looks clean. I had JJ do one of my older Heyms the same way before Heym was doing them all this way. Chris will sell you the low profile mount Im sure.

Another quality but non intrusive method is to build a base that is fit to the slot for the rear sight. Costly but no extra holes and slick when done correctly.

I would second JJ as he has cut the rib on an older Heym 470 I have and I was going to get him to do my Merkel 470 but I sold the Merkel. The nice thing about this method of mounting is it does not show when the red dot is removed unless you are really looking for it.

I see they sell the mount at Heym. I will call JJ tomorro and see how far out he is.

Key questions here:
-- how wide is the Heym rib?
-- what does the base use for a recoil stop?

JJ did my 45-70 and .577 NE. Worked out great with Dokter but Aimpoint affected regulation too much
