So easy question I know you can shoot 40 out of a 10mm pistol but does it work the same out of an AR pistol?

I have a lot of 40 ammo most JHP that I have had no luck selling so thought I'd do a build if I can't sell it then I'd have something other then the one pistol I own that shoots 40.

It should work fine.  You might have to lower the buffer weight a little.

ETA:  Hotdog might be right.  Depends if the extractor catches the rim or not.

Since  both would headspace on the mouth  the shorter .40 wouldn't work in a 10mm AR style semi auto.

I don’t think shooting 40 in any 10mm is a good idea.

Certainly can be done but not a good idea

Pretty regularly done, @ least up until the ammo panic.
