If you check out the design overview for this Kimber K6S DASA "Magnetron" revolver build you'll see that this build has 3 main elements: the barrel shroud, the magnetic holster (hence the name), and the red dot mount. I decided to tackle the red dot mount first.
There are only a few options for mounting red dots on revolvers. The off-the-shelf mounts only fit specific guns and optics. There is no such mount for Kimber's K6S, so I need to make one for this build.
I'm planning on using a Holosun 407K red dot and my plan to mount it is pretty simple:
Buy a replacement rear sight for the K6S
Buy a mount for the Holosun 407K
Destroy both with a combination of dremel and knock-off drill press
Permanently attach them so that together they make a legit K6S red dot mount
Here goes nothing.....
The image below has all the components. The top is the DPP Mount which is intended for a Springfield XD, the middle is the aftermarket rear sight, and the bottom is the rear sight that the K6s ships with. What I need to do is grind off the dovetail on the DPP mount so that it has a flat bottom that I can attach the the rear sight.
Here you can see that the aftermarket sight (right) has a flat top and overall lower profile than the sight that Kimber ships with the gun. This means it requires less grinding to prepare for the red dot mount to be permanently mounted to the rear sight which will then be mounted using its dovetail that is built for the K6s..... Lot's of mounting.
I started with the DPP Mount. I needed to remove the dovetail it came with and make the bottom flat.
Then some light sanding on the K6s replacement rear sight and the surfaces they're ready to mate.
To ensure a permanent connection and therefore an accurate red dot, I planned to use both a bolt and JB Weld to connect the red dot mount to the rear sight. That meant I needed to countersink the red dot mount plate so that the bolt head didn't interfere with the Holosun.
I don't have a drill press (I know, shame on me) so I picked up a drill guide which helped keep my drill angle square to the mount and reduced the risked that I drilled too deep. It worked better than expected and the drill guide is much smaller than a drill press.
So, how's she look on the gun? Pretty good, but there is a larger gap between the front of the mount and the top of the revolver than I would like. I want as much contact between the mount and the gun as possible to support it and limit the chances of it moving or breaking.
A bit more sanding and the gap was removed. This Fudd revolver red dot mount is ready for action.
The 3 pieces ready for cleaning, gluing and painting.
