AAC / Remington Model 7 - looking for a night vision length picatinny rail - any Help or Ideas appreciated

[dckoch]

I own a Remington / AAC Model 7 in 300 Blackout. Gun comes with a 5" picatinny rail already mounted to the gun. I was wondering if anyone knows of a mount or extension that could work on this model so I could put a forward Night vision or thermal device on the gun in front of the scope. Making a short range, suppressed predator rifle.

Thank you in Advance
