Hey Nitro450exp,

That is a neat setup!
I got lucky with the stock trijicon mount that just dropped onto the Krieghoff rail!
Needs some fastening to keep it in place, but seems to be good now!

I have fired about 10 rounds now and am getting nice results and certainly easier on my eyes that iron sight(unfortunately!)

Looks like this will be my setup for 2 months time!

I cannot wait! Packaging and repacking already!

--------------------
Decisions made.......now to find the gun!
.450NE is still the dream, but along came the Krieghoff .470NE.........couldn't say no!

I've just mounted an RMR to my Heym .500 double. The RMR mount comes with a locating pin that one can use a small hammer and gently tap the pin into the underside of the mount that assures the sight won't slide along the rib.

Fortunately the Heym rib has a locating hole on the top of the rib parallel to the front of the mounting grooves machined into each side of the rib.

Unfortunately, the right claw on the mount can't fully bottom in the groove on the rib because the locating pin locates the sight just a tad too far forward so that the very front end of the claw touches the rib just past where the right side groove stops.

Fortunately I have a teeny tiny file that I used to file off the front 3mm of the right side claw on the mount and presto! the mount now fits perfectly and the locating pin assures that the sight will not move forward or aft under the heaviest of recoil.

The sight works absolutely fantastic and I couldn't be happier!!!

The locating pin of course is optional however one may under heavy recoil experience movement of the sight without it and in addition, return to zero may possibly be inconsistent upon removal and reinstallation of the sight.

Now I need to have the grooves and locating pin hole machined into the rib of my Merkel so I can mount an RMR on it as we'll.

Gentlemen,

has any of these sights caused the regulation to be off. Assuming your DR was regulated to open sights, OR a scope in the first place?


When at Heym, I was interested in having ALL THREE, ie express sights, scope and a dot sight. All may regulate differently I was told. Just for info - not to go off topic - So in practice, I would have had the rifle regulated for the scope primarily (.375 Flanged), then open sights a good compromise to 50 m (ie for 0 to 50 m they would work well enough, crossing before 50 m if regulated for a scope say to 100 m). The dot sight, I would have just hoped was similar to the open sights, but was told it is different yet again. I could not go ahead with this planned rifle due to changed economic circumstances.

So just for info, interested to see if changing from open sights to a dot sight has affected regulation in a noticeable way? Thanks.

The RMR made absolutely no difference whatsoever to the regulation. It weighs almost nothing at all. It does however make one's sight picture a little more consistent/easier particularly for older eyes. My composite groups didn't really change between irons and RMR. Still maybe 2" @ 50 yards. The irons take an incredible amount of attention and focus for me to do the 2" though whereas the RMR will produce similar groups with a little less work aligning the shot. I don't have facility to mount a scope on this gun and I don't think I'd want to. The .500 is on the very upper limit of my ability to handle the recoil and a scope unless mounted scout style would surely remodel my eyebrow in short order.
