M40A1 repo mounts and rings

[Frank Green]

From what I gathered. There are at least a two or three different profiles to that cap that has been seen. Also they’ve seen blind holes, the two hole variation which is being made as I understand it (which are all threaded so you can move the cap a little forward or back) and a 3 hole variation.

Thank you for the info Frank, I am FAR from knowledgeable on these things so I appreciate the explanation.

Hey all. Not to keep harping on the subject of the ring screw hole width spacing, but want to clarify my previous posts on comparisons between these group buy repro mounts and others, and in regards to simrad cap fit and compatibility.

So another mount I recently acquired that was advertised as a real Unertl mount turns out to probably be a TMA/TheHogsDen mount. After a credible authority on these items questioned whether the mount was a real Unertl or not, I pulled out a couple of loose real Unertl mounts I’ve had for years (even before clone/repros were really a thing).

Comparing the two real Unertl mounts I have with the other new mount I recently acquired, there was a very slight difference in the rings’ screw hole spacing. The two real Unertl mounts’ rings hole spacing is just slightly smaller than the new mount’s.

The Badger simrad cap fits the real Unertl mounts perfectly, but the screw holes are very slightly misaligned and will not work on the new mount:

The TMA simrad cap I have fits perfectly with the other new mount I recently acquired, reinforcing the point that the mount is a TMA too. Interestingly, the TMA simrad cap also fits onto the real Unertl mounts, although the screws grind a little bit when tightened down due to the slight screw hole spacing difference.

And neither simrad caps will work with this group buy’s mounts, due to these mounts having slightly wider screw hole spacing still. So looking forward to the simrad caps that will be made for this group buy!

My TMA mount will fit Redfield ring top half’s on it. I was surprised it actually would

Sounds like $175 for the Simrad Caps.

@Frank Green Do we contact you to get in line and pay for these simrad caps?

Let me ask how to work it. I'd like to get out of trying to put this all together. I just don't have the time. Hang loose I'll ask.

Is your Simrad cap an original?

If so there you all have it. That's got one thru hole. So that would confirm that there are blind holes, a single thru hole and as the ones being made have a dual holes. Supposedly even three holes.

Yup, looks like 3 hole (on either side, so 6 hole total) simrad caps were used in service. The TMA simrad cap I have is the same way, but not drilled all the way through. With the angled sides of both the cap pictured and the TMA cap, hard to see any but the center screw holes being used, as using either of the end holes would offset the cap off the bottom ring. That would not be an issue on the caps with squared sides, I don’t think.

That top simrad cap setup is the first time I’ve seen the the regular top ring half used as an undercarriage ring. Looks like that would be a lot more physically stable than relying on one small screw on either side and the scope tube itself when a heavy NV optic is clamped into the cap!

The maker is going to be putting them on Ebay. That's what he just messaged me.

Yes, I got a bunch of NV stuff from a fella years ago who did a lot of work with kn200’s and kn203’s
