Your Ranger is definitally a model 94. The Ranger is just the "utilitarian" grade model 94 with cheaper wood. It is an angle eject so it will accept both a scope or a reciever sight.
If you go with a reciever sight you just need to specify one for an angle eject.

As far as scope rings most manufactures make them for the angle eject 94.

I have a Ranger with a Williams Foolproof reciever sight and love it. It is very fun and cheap to shoot.
