Another optics idea….Levels

[xswanted]

I know Sig Sauer is using anti can’t indicators in some of their optics.


Is there a scope out there with a built in bubble level?

How hard would it be and would it be feasible and/or cost effective to integrate an external bubble level machined into a scope that is leveled with the crosshairs?

It seems like if a 39.99 archery sight can glue on on a $2500 scope could have one machined in somewhere.

Springfield Armory used to sell scopes with a bubble level in the bottom of the field of view. Along with an early FFP reticle that was all but useless at lower powers. Not sure if anyone else made them. At the time, scope manufacturers struggled to get the reticles within 3 degrees of plumb. Then stack the same error in positioning the level inside the tube...

Konus make scopes with a bubble level inside (eg. Konuspro M30 12.5-50x56).
But I don't think I'd want a Konus.
QC is dodgy, bubbles aren't mounted level to start with, etc.

The Revic PMR428 has a built in level in the heads up display.

USO had them for years
