RMR co-witness direct mount for SP5 - Page 1

[ARCHIVED THREAD] - RMR co-witness direct mount for SP5

Posted: 2/19/2021 2:22:25 AM EDT

After scrubbing the nets looking for a way to directly mount an RMR to my SP5, I quit looking. Instead I have designed one. I have a guy that will mill them on a Hass robot. The rub is he wants to do ten as a minimum.
I believe I have a very good solution, I just need to feel out whether or not there is a market for such a mount. It indexes on the tab at the top and allows the iron sights to align just below the red dot in the glass.
The front sight hood and the body of the RMR frame each other pretty well, providing a working answer to the co-witness question.
Am I crazy? Any body interested?

I'm interested in something like that. Able to figure out a price for the item and any possibility of showing a proof of concept?

I will probably early march. I have to cast some signal cannon barrels before he writes the program.

I still can’t believe no one has made an aimpoint acro mount for the MP5. Seems like an ideal red dot for the platform that would co-witness.

What about the KAC RAS and optics mount?

Take look at this

I have it on mine and I love it. It replaces the rear sight assembly. I mounted an SRO on mine, so since it's round if the sight ever dies you still have a diopter of sorts and can make it work

I have the M8 industries RMR mount on my SP5K as well. I liked it so much I bought another for my FA SP89. I may try a Holosun on that one. It’ll be interesting to see how it holds up to FA fire. I suspect it’ll be fine since they are designed for a pistol slide which is a much more violent action than what you get out of an MO5.

Those are all good solutions.
But I want to retain use of both iron sights. Real co witness.
I actually like the castle rear sight and think with the rmr mounted low enough it will create a very intuitive sight picture.

I have the battle steel (botach) Aimpoint micro mount. Not an rmr but it’s a beautiful perfect co-witness. The front sight circle is perfectly around the dot and doesn’t interfere at all with the sight picture. The only bad thing about it is the stupid white bold battle steel marking on the side. I ended up having my blasted and cerakoted.

I'd be in for one if the price is reasonable.

I contacted Botach and asked if they (or whoever makes the mount pictured above for them) would make one for an RMR--it seemed like a no-brainer for me. Alas, they never responded. If that is what the OP is talking about--a mount like the one pictured above but for an RMR, I'm in.

YES!!
Similar as the one above, however, maybe with only one claw. Trying to work it so it won't obscure the SN.
I will get it worked out with anodized finish for under two hundred bucks.
We are working the bugs out now, so I'll have more shortly.

On mine the serial number isn’t covered with the optic mount, but I’ll have to look at my sp5’s to see if it’s in that spot. Have you checked out the shield mount? It’s similar to what you’re asking for but the footprint is the shield and delta point pro.

I have a shield mount that I already machined to fit the RMR. It works, but is a little ad hoc That was my first stop on this project. After my buddy machined the SMS, he suggested we make one specifically for the Trijicon.
He bored a number of small signal cannon barrels I had cast and wanted a few, so one hand washes the other. If anybody wants a signal cannon, Im yer huckleberry.

Interested. Just out of curiosity, whereabouts in GA are you?

This is exactly what I am looking for, except with the RMR footprint.

I'm interested. Maybe drill more holes to make it universal like these MRA mounts? https://outerimpact.com/product-category/red-dot-sight-adapter/

Tagging for interest as well. Prospective buyer depending on the price when all said & done

Great. I'll update on this post, hopefully next week. I do appreciate the interest, and input. We are working on it now.

Get a PTR instead.

Seriously though, how does it attach. If it messes up the finish anywhere, I think folks will shy away from it. Most SP5's are likely fairly safe queen-ish.

Sounds dumb but very true for me. I only put optics on my mke guns because those top rails really do scratch up the finish quite a bit. I do prefer the looks of no optics but a nice red dot does make a huge difference.

I gave up trying to mount an optic to MP5’s that don’t have a welded on top rail.Those claw mounts mess up the finish and although fine for range use if you are anything other than gentle with them they are easy to knock loose.My PTR has a Aimpoint with lower third mount and it’s perfect because I have a red dot and can still see underneath the red dot and look through my irons.

Any updates? I know people can Pooh Pooh all they want but for those that this fits what their looking for it’s a great idea. Co witness on a hk in an AR world isn’t an easy thing at all

We both had spring break for our kids on different weeks, and a few deadlines for other projects. Ya know, the kind that pay.
I have a working solution, but am needing an hour or so of time on the robot to iron it out. So I am hoping to post something soon.
I will say, it is a viable solution and a very nice sight picture
