Iron Sight Measurement

I’m currently away from my firearms for another week or so and need some measurements, I need the height above the top of the receiver to the top of a Troy folding rear sight while folded and to the center of the aperture when deployed.

I’m looking at getting a USO SN-3 1.8-10 TPAL scope and mounting it in a Larue SPR mount, but I want to make sure I get the right mount so the scope will clear the BUIS while closed and yet have the ability to have the same cheekweld if possible.

I got 1-7/16" to center of apeteur and about 7/16" folded

Awesome, thank you for the quick response.
