UM Hinged Scope Rings

[Juan_ID]

I figure there’s some scientific engineering behind it but what’s the reason for the offset screw holes?

That’s a sexy rifle!

And S/N 001

Not sure what you mean by offset holes. You mean why at the top? And a hinge pin?

Most scope rings are “clamp” like this, the rings in this post are oriented like the red line.

It’s just how the design ended up, maximizing strength and holding force, and making them light. It’s the equivalent of 6 screw rings but the weight of 4 screw rings.

Ready to sell the less sexy one?

Not yet. She will be a tough one to give up, lots of hate(in a good way) in a small package.

A quality direct tikka ring is decently a hole in the market.

Let’s see the drop test!

Might need a few sets.

Any way to adjust the bubble?

No need to adjust the bubble because it’s built into the base.

Well .... I got all excited, then checked the webpage to see that the highest option will only be 1.25" ...

I'm in the camp of modern positional/field shooting, where 38 mm / 1.5" - maaaybe 25 mm / 1.38" - is the way to go.

@Unknown Munitions: any chance of higher rings in the future?

Yes, we will release 1.5” versions in 30, 34, and 35 next.

Spirit level ambidextrous?

Spirit level ambidextrous?

Yes, flip your rear ring around 180 degrees!

Great!

Any ETA? Even one we won't hold you to?

@Unknown Munitions

I wanted to bring this back up and see the expected ship times? In post #50 I have that exact scope and a machined 2 piece rail on my ruckus action with a carbon barrel which I'm sure is very close to what the pic shows above. What height rings would you suggest? Lows?

If I order a set I'm sure you could Cerakote them as well?

 

[PNWGATOR]

Can’t wait to see how these drop test and hold zero.

Literally all that matters with rings.

UM Premier Scope Rings - Unknown Munitions

Installation instructions found below. Built by hunters, for hunters, because we know what we want in a scope ring! Low profile and wider than average rings at 1″ for big magnum security and only 4.5 ounces! Machined from 7075 Aluminum with Nitrided hardware that won’t rust. Machined grade 5...

How hard is it to knock the level off? I'd rather not have one.

Looks like two screws….

Not exactly. It would be the equivalent of 6 ring screws if you ignore the effect of friction when clamping but if you account for friction it will be less then 6 (but still likely more than 4). For instance, if one were to assume a coefficient of friction of .3 between the rings and scope tube (just a wild guess) then this design would be equivalent to about 4.6 ring screws.

Also note that by removing material in the middle of the ring you are reducing surface area which will increase contact stress on the scope tube at any given clamping force. Since you are (most likely) increasing clamping force compared to a traditional 4 screw design but appear to have similar SA to a traditional 4 screw design you are potentially adding a bit more stress into the scope tube which might be problematic for some manufacturers unless you reduce ring torque slightly.

Are you taking pre orders for tikka rings?
