LEUPOLD MK 4 4.5-14x50 SCOPE RINGS AND BASE RAIL

WHAT BASE RAIL DO I NEED AND WHAT SIZE RINGS TO GO ON A REMINGTON 700 308 5 R 20 INCH BARREL. THANK YOU FOR YOUR HELP.

Any picatinny rail drilled to fit the Remington. Rings to fit the scope, as long as they're made to fit on a picatinny rail any will work as long as they fit the scope.

I suspect on the rings he was hoping to hear low, medium, or high for clearance.

A 50mm is fairly tall, but with the rail, I suspect you can get by with medium and possibly even low. I think there are sources online that can tell you which you need-you might even try Leupold, see if they have a chat or a hotline.

I had a MK4 with Low Mk4 rings on a 20moa rail and it cleared just fine. I will have to see if I can find a pic this evening. This was on a savage FCP-10.

20 MOA RAIL DO I NEED LOW MED OR HIGH RINGS

Probably medium, if they happen to not work then take them back.

Low rings with a nightforce 20moa rail.

Medium rings work the majority of the time.
