I thought I would share this for those interested. It took awhile and cost as much as the RMR due to 3D modelling and scanning the firearm but I am very happy with the fit and cheek weld while in use. I also managed to get it low enough the irons are still visible and somewhat useable but by no means co-witness.

It does shoulder nice and naturally lines up to my eyes so it should perform well.

Cerecote colour was midnight blue for a nice finish.

That looks great! I don’t think you can get lower than that!

Really appreciate your post. JJ is putting one on for me for my SRO for my 470
 
Thats really cool. Where could I purchase one?
 
I can inquire at the machine shop I had cut it, but this was really just a one off as nobody offered what I wanted and I didn't want to mill the gun at all
 
Awesome thank you. Did u already have the screw holes drilled into the removable scope piece or did they drill into the vent rib

same question I had. My Merkle just has the complete rib with no take out section. It is a 140 AE Safari. My questions are the following please:
1. Does your Merkle have the same thing as mine...no take out section already there as their 160's have?
2. If not, how does your mount bolt on?
3. If it is a bolt on, I would love to buy one from your gun smith versus having to get JJ to mill my mount.

Please let us know...greatly appreciated!!!
 
The firearm was not modified in anyway. It had the factory removable dovetail. this was built to utilize this cut out. If I was going to mill the gun I could have achieved co-witness.

The new mount bolts on with the same two factory allen head screws that the dovetail used.

I'm not sure how it works here for posting links to companies but if its ok I will. Great local shop who specializes in high end tactical builds mostly.

@P-J I'd also be interested in one if the machine shop could make another pretty easily. I was going to get it done at some point locally but if it's already been looked at and measurements and what not have been saved, it makes sense to have it done there.
 
You just made me want one for my Merkel
 
Congratulations on a very nice solution.

Although not a trivial task, and somewhat expensive, I believe it would be possible to engineer a mount in such a way as to get it lower.

Two factors make these mounts thicker than they need to be:
i. Most are machined from aluminium which requires greater thickness than steel (or titanium) for strength.
ii. The base plate sections of most mounts are drilled and tapped to take the sight attachment screws. This leads to a minimum thickness in order to get sufficient thread engagement.

The Shield company encountered this problem when they designed their mount for the Glock MOS system. Their solution was two part. Firstly they made the mount out of steel and used thin headed screws to attach to the slide. Then, instead of having the base thick enough for threading, they designed the mount so that the sight attachment screws threaded into raised pillars. This enabled the Red Dot sight to be low enough to co-witness with standard sights.

This would be an expensive project for an individual to design, machine and test a similar approach for double rifles. However it should be a piece of cake for any of the double rifle manufactures.
