Question on Optic Rail for M77 MKII Rifle

[QB]

I decided to mount my Aimpoint H-1 on my M77 MKII for now (versus using the rings and buying a scope). Does anyone know what brand/model rail to buy that will fit the M77 MKII? I'm not sure if the rail has to list the M77 or if the one that fits a Mini14 will work. I'd like a stainless rail but black will do since the H-1 is black.

Thanks for any suggestions.
