I'm done messing with the mini and regular scopes. Almost ready to just go open sights but was thinking of trying a red dot type sight. My question is my Ranch Rifle is milled for the Ruger type rings which I've used to mount different scopes, but most of the cheaper red dot scopes I've seen already have the mount attached. What do I need to get to install one on the mini? And I'm only looking to install a cheap (less than $100) red dot as the accuracy of this gun doesn't deserve anything better.
