rail mount for a 7/8" laser

[panamino]

I am hoping that someone out there knows the thing to use to mount a green laser to my ar10. It measures 7/8" thick which is too small for the normal 1" mount to work on.

Either of these will work, very well.  VLTOR mounts, you need the E-Series, they clamp down to 0.803".
