A new whatziss...

So, tell me - what *is* this?

A new whatziss!

I'll be more charitable than usual... here's two more views. One. Two.

Comrades, Azimuth alignment tool for a compass..... Training sight for a mortar....... Device for plotting fall of shot on the range..... Respects,
 
Looks like a variation of a sextant, therefore I'll guess a rangefinder.
 
Well, my first thought is some kind of field sextant since it has sun filters and the geometry looks right. Given the armorer's background and the hairline sight that doesn't make much sense for taking a sun shot it makes me wonder if it isn't some kind of quadrant for figuring out sight to crest. Or a weird aiming circle... How many guesses do I get?
 
Bore scope aligning guage thing, sortof.
 
I wanna say it's some kind of sextant as well, but AW1 Tim may be on the right track with the trainig sight for a mortar. (*of course, it may also be a Knooter valve...*)
 
collimator
 
Is it okay if I just say it's a pretty cool-looking thing and I want to own one just for the heck of it? Mount it on the cab of my truck? Get lots of chicks?
 
I think it looks something like a Rube Goldberg stapler.
 
Optical rangefinder. You adjust it until the view from the two top mirrors merges into one image in the eyepiece, and when they have merged you then have the range to target on a dial.
