Opinions... range finder for my “optics hub” - type/mount?

I’m looking for opinions on what range finder I could mount to this optics hub mount? Useful range would be <1100 yards, and I’d prefer not to use a “tray”, but something that would mount to the side/top of the m-lok frame (currently using RRS mount for the inverted scope)... do I have any options? (Kestrel linked... perhaps TerrapinX or Leica offering?). Thanks for the help!

Outstanding! There has to be a market for this - I made 8 calls, to som of the bigger players... no help. 100 points to you! I was hoping to find a m-lok Mount (tripod head) to mount a TerrapinX on top... no lock yet. I new skipping shop class in grade nine would come back to haunt me! Thanks for sharing!

Why not a mini ball head turned 90 degrees?


 
I'm really disappointed that the cheese plate standard isn't being adopted for optical shooting accessories.

What kind of Mlok device do you need on a spotting scope?

On the other hand, pretty much everything optical has 1/4" thread so you already have one foot in the cheese plate pool.

The best would be to do both in an intelligent way and someone really should start making real Picatinny rail that can mount to cheese plate.

On to the rangefinder, you can get a Sig Kilo 3000 BDX and an Outdoorsman mount which will link to your Kestrel and give you the advantage of binocular vision.

Is there a way to bolt an Outdoorsman mount to that spotter? If it was cheese plate compatible it would.
 
I’m almost ready to order... RRS clamp on top of the inverted Optics Hub, with a TerrapinX and RRS mount. LRF will be in line but “elevated”. The only drawback... RRS 1/4x20 holes are 30mm on center and the Hub is 1 inch... may have to dril/tap the 2nd hope. Nice thing (if it works- TerrapinX can be mounted on the RRS if the Mark 4 spotting scope is left in the box.
 
Don't over think it. Since you have an Optics Hub, you're way ahead of the game. You can adjust the spotter side to side, or up and down if turned on its side. Then mount a RRS clamp on the side of the Optics Hub, which you can adjust it's pan or sweep opposite of the set screw adjustment within the Optics Hub for the Spotter. You put a rail on your LRF, and clamp it with the RRS clamp. Very simple.
Picture is an example...

Alpine... great photo... thanks. I have my scope inverted... it should work... key question- will “one” screw in the clamp hold the LRF from twisting... do you wish you would have used a RRS clamp with two screws? Reason I ask was based on the advise of Michael from RRS... and two screws complicates things. Thanks for sharing!

I don't run mine that way, I configured it as an example for you. But you can use the one screw clamp, and won't have any movement if you put some antiskid or friction tape between the clamp and Optics Hub. I have antiskid material on my platform as pictured below, and the one screw attachment is rock solid.

Now what you may run into, having the LRF far enough back to allow for the same eye relief as the spotter. If you cannot move the LRF to the rear enough on the Optics Hub, a simple solution is just buy a $12 cheese plate rail, attach it to the Hub, and have it extend rearward, and then mount a single screw or two screw RRS clamp.

Something like this example:

Part of the reason I bought the Ranger was to fab an MLOK mount using the pocket clip holes, but wound up going another way.

This worked OK; it's made from leftover action cam mounts:

This was hacked out of aluminum bar stock with a shaped area and adhesive rubber pad to fit the LRF contour:

The mounting bolts and thumbscrew (from an Arca style plate) give enough adjustment to cowitness with the scope and stay that way, but the main goal was locating the eyepieces so they are both usable with a small shift of the head. I haven't seen other LRFs positioned this way, but once I tried it there was no going back. Of course, a Radius solves both issues--why is the external display such a a rare feature?

I would love to have a mount like this. ..
 
I appreciate all the help, and the ideas provided… especially the assistance of Michael from RRS, the folks at Kinetic Development Group with the Optics Hub and Jason at EuroOptic we were able to retain the features of the Terrapin X, and provide a modular solution depending on need (alignment is not perfect between the optics and the LRF, but it’s close). Final shout out to the folks at Cole-TAC for the extra large rain hood! ??
