Rifle Scopes USO 37mm objective ID?

[Ratbert]

Can anyone tell me the inside diameter of a USO 37mm Objective/sunshade? I'm wondering if I could fit a 37mm ARD honeycomb into my 44mm Falcon sunshade, but I no longer own a 37mm SN-3.

I can take a measurement of my Sunshade with ARD this evening when I get home from the office. Give me bout an hour, unless someone beats me to it.

Don't forget the USO is US made and your Falcon is Chinese-made, so they may have different thread pitches even if the diameters are the same.

I just want to stick the honeycomb add into the falcon sunshad, not screw a USO sunshade on

According to the caliper dial, the inside diameter of the sunshade is 1.738".

Just got home & hit my 37mm sunshade with the calipers...

I got right at 44mm inside diameter

47.25mm outside for a Butler Creek

Thanks guys. Unfortunately.. Damn.. the Falcon sunshade is around 50mm ID.

Strange, I remember the 37mm USO 'feeling' bigger than that.

Maybe I could trim down a 44mm USO...
