Need Leshiy sight height for ChairGun

While the previous poster is correct, we all know that it’s very hard to measure that via the traditional way on a Leshiy.

But here is a little trick I came up with:

Fold the gun in half, and (temporary) put the scope in such a position on the rail so that the end of the eyebell is flush with the breech. Now it is very easy to use the formula from above, or even to measure from the center of the bore to the center of the eyepiece directly with calipers. Easypeasy!
