Will these rings and mount work?
 

I know it is hard to tell from this pic but i am going to order a new scope for the remington 7400. Should i replace the rings and base? I will prob buy a 30mm tube so the rings will need to be replaced but...if i dont and get a 😄1 inch tube, are these rings worth using or should i scrap it and start over?

I inherited the gun so have not idea of the brand or history ofmthe rings n bases

Sorry, just realized i posted this in classified by accident. Dont think i can move it. Still hope to get some feedback on question...

Thx
