Does anyone have the blueprint dimension between the top of the picatinny rail on a flat top receiver and the center of the barrel extension hole?

Thanks

The drawing I have from a CAD model shows that dimension to be 1.250". it is not an "official" government drawing though.

I got my S/W file from cncgunsmith.com. So Im not positive if thats 100% correct or not . Hopefully someone can give you a definate answer,maybe be give Randall(ar15barrels), Denny(dennysguns) or Mike(LaRue) a call Im sure one of those guys could get it for you.

I think I can live with a small amount of error. I need this dimension to confirm the height of my scope over my bore for some trajectory calculations.

Thanks guys.

I just got the Q/A guy at my work to check this measurement and he was coming up with 1.212" and I was getting a crude measurement with my calipers and was coming up with about 1.213" or so and this is on a stripped CMT upper. Hope this helps.
