can anybody tell me if there is a solid 1 pc base out there(weaver style) for my rifle. mine has 2 pcs and the front hangs over into the bolt area unsupported and the front ring sets right on top of it.im thinking if it were full length it would be a little more ridged and have a little more adj. for fit. its a round front,flat rear. or will there be a problem with the ejection of the 300win.mag brass.
