Our representative in Switzerland field tested this new OBM scope mount system on his long-range custom build for the K31 rifle.
The stock is gorgeous.

Any details you can share on the stock, barrel and scope mount? I have a bubba’d up K31 in the safe that I bought specifically to do something like this with a number of years ago. I want to find someone to modify the existing barrel tennon to take prefits, make a relatively lightweight composite stock for it and get a proven reliable scope mount.
Where does the brass eject lol?
Good morning. The receiver and the barrel are original K31. The stock itself is a custom stock made in Switzerland specifically for the K31 rifles.
The scope mount is the new OBM (over the bore mount) made specifically for the K31.
Clean ejection is 100% and directs spent brass left side of the receiver.
Since the K31 is not identical from one rifle to the other as pertains to ejection direction, the deflector is adjustable.
The device on the muzzle serves as a brake as well as a harmonics damper. I think you can tell that the barrel is free floated on the rifle in the original photos. The photo below shows the mount on an issue K31 and you can see the adjustable deflector bit better.

What about the eye relief? Is it ok?
Judging by the photos, the ocular lens looks a bit too close to the eye.
