What is the height of the rear of a DPP?

Can someone please bust out a set of calipers and measure the height of the rear of a DPP?

I just ordered one and cannot find that dimension listed anywhere online.

Mine is mounted on my Glock but it looks like .50”. I had to eyeball the top because of the slant there.

Mines mounted on my Staccato C2 and I got .50 as well. Hope this helps.
