Can anyone tell me what the measurement is for a rifle with the factory picatinny rail is?

I need it from the top of the base to the barrel for the Mil-Rad calculator but can't find it.

I have 24mm rings but I don't think they will be tall enough with a 50mm objective.
 
I assume by 24mm you’re referring to center scope height?

I can’t help with measurements but when I bought my Sako TRG 22 6.5 CM it had the factory rail and I had this scope: https://vortexoptics.com/razor-hd-amg-6-24x-50.html?vortex_reticle=240 (50mm objective) with these rings: https://vortexoptics.com/vortex-precision-matched-30mm-rings.html?vx_ring_height=930 (.97 inches / 24.64mm center scope height) and the scope with Vortex flip caps installed cleared the barrel.

I’ve since removed the factory rail and installed a Spuhr ST-3701 https://www.milehighshooting.com/spuhr-st-3701-trg-30mm-mount-7mil-24moa-1-378/

That helps a lot...thanks!

Yeah I was referring to center of scope measurement.

How horrible was removing the rail? I'm tempted to do it, however, I'm a little scared too after reading some horror stories.
 
I used a heat gun with a reducer tip (to restrict the heat to a small area) on the screws and rail. The rail seemed to be held on with some kind of epoxy and to remove that I used Klean Strip Strip-X Stripper (use in a well ventilated area) and a plastic scrapper, just take it slow and easy.

My screws were Torx which made them easier to remove than the older Sako rail screws which were straight blade and easier to strip.

By the way, there were two locating pins on my original rail so if you tap on the rail to remove it, make sure to do it evenly.
