TC Bench Mark Weaver Rail

I just purchased a TC Bench Mark in .22LR
I want to set it up with a night vision weapon sight to care of some coyotes near the house.
The rifle came with two short Weaver rail mounts screwed into the top. Will a regular Weaver rail (6" long) screw into it or do I need a special rail? I did not see one on the TC web site
I would really like to put a Picatinny rail on it but don't of a solution

Thanks
