RMR Base + Adapter for Chapuis Doubles

[Tom Leoni]

All ~

I wanted to announce that, starting in 2026, every African grade Chapuis double rifle (.375, .450-400 NE and .470 NE) will come with a free base and adapter for RMR red-dot mounts.

I was able to negotiate a great price with the incomparable Andy Larsson of Skinner Sights, and I am happy to be able to offer this added value to the double rifle community.

The way it's mounted is:

1 - Carefully unscrew and remove the front scope-mounting block in the quarter-rib. This requires a very fine screwdriver and it is often best done by a gunsmith, so as not to damage the engraved screws.
2 - Place the rectangular base in the now-open slot, and screw it in tight with the supplied Allen key.
3 - Mount the red-dot adapter on top of the base by tightening the adapter's two screws with the supplied Allen key.

If you have any suggestions on how to further improve my brand's value, in the immortal words of Dr. Frasier Crane, "I'm listening." ...As long as it's feasible and cost-effective, of course

That is huge, and wonderful news Tom.

When the first shipment of RMR bases come available, I’ll be first in line… I definitely want to mount one on my wife’s Iphisi..

Count me for one

Great news Tom! When I bought my secondhand Chapuis 375 in 2017, I had a gunsmith in Dallas remove the block in the rib and make a base for the Trijicon RMR. It fits flush to the rib and works great.

Great news!

If this part fits a UGEX 9.3 I'd love to buy one...its hard to organise anything like this in Australia, Land of the plastic Tikka

Hi Tom,

Exciting idea - do you have a photo? I'd love to know about height over bore etc

Thanks,
Jack

All - 20 units of the red-dot mount for Chapuis African-grade rifles (Iphisi and Elan) have just come in. These are not the ones made by Skinner Sights (which I'll be including in all African Chapuis doubles once they come in from Montana); these are the all-steel, one-piece mounts made by Chapuis, with a Weaver profile.

Part number is 66027--it can be ordered through any FFL dealer near you.

I'll be ordering more in the future.

 

[Surgeon1]

I definitely need a base for a 470 when available

I would get my FFL to order one ASAP, since I have only 20 here.

Tom,

I think this is a really smart business move by you and Chapuis, well done. I purchased a very nice used Chapuis 30-06 double a year or so ago and you and I had communication about fitting a RMR, in my case things were slightly complicated as I already had removable scope bases in place. I finally used the existing rear mounting block with a Trijicon 12-14 mm rail mount adapter and fitted an RMR.

In this day and age, considering the rising cost of double rifles, I think including scope mounts / red dot mounts is adding a lot of value and taking away a lot of headaches for double rifle buyers. I just purchased a number of mounting options and 3 more RMR sights to outfit my Chapuis double in 30-06, a Valmet o/u double 30-06, a Benelli R1 semi auto in .308 and a Blaser 97 o/u combination gun.

I put my Krieghoff big five double in 500/416 NE to serious use earlier in the year in a large cull hunt in Australia fitted with an RMR, I'm convinced that the RMR is an awesome solution for double rifles, particularly with my aging eyesight. I'm doing a bit of European driven boar hunting and looking forward to using my medium caliber doubles / combo guns with RMR red dots fitted.

As a consumer I look at optic mounting solutions as an important part of assessing a gun, if the manufacturer provides those options with the gun, that gun will definitely get interest from me. We shoot a lot of Blaser R8, the fact that I own many Blaser mount options has made me fit Blaser compatible one piece scope rail bases to other rifles such as Tikka so I can fit existing, red dot, scopes and thermal sights.

Personally I like the 3.25 MOA RMR Type 2 red dots, I'm using them out to about 100 yards and like the fast target acquisition and the use on running or moving targets.

I'm sure Chapuis will continue to grow and get support from new customers having solved the red dot mount issue and including a new mount with every new double.

Tom, I don't want to "hijack" this thread / post, but I would like to know what ever happened to the idea of a 450 -400 double for under $10,000.

He answered in the original thread that with tariffs and other cost increases that’s isn’t possible at this time.
