Rail for a traditional scope or like a scout type rail or a chassis type rail for lots of accessories?
I had an Arms on one and have a Smith Enterprise on one. Arms is a bit lower. If I were going red dot above tha action the arms would get my vote if I could then cowitness, smith gets my vote for a scope as you have to get the scope high enough to clear the rear sight assembly if I have to go higher I might as well have more clearance for the ejection port.
For a scout type setup which is my preference for a red dot I’ve got a Ultimak. Can’t offer advice or experience on the others but there’s been one shared quite a bit by other users.
As for an accessory rail that would wrap around or a chassis sytem I can offer no advice.
