How to tell if I have Weaver or 1913 rings

[Jgrovem110]

I just bought a retro aimpoint 3000 and it came with rings , is there I way I can tell if they are meant for a weaver or 1913 rail?

The cross slot of Weaver rail is narrower than the cross slot of a 1913 Picatinny rail. You can use a Weaver ring on a Picatinny rail but probably not the reverse unless you Weaver rail has wider than usual cross slots

Okay wel I just want to make sure they are infact weaver before I purchase a scope mount
