Helpful Positive Review Weaver Extended Multi Slot Bases by SuperKawumm, September 14, 2014

Most Recent Review Very good base for the money. by Legacy Reviewer, January 5, 2014
Mine fit very well. Used their hardware. Guys who complain the rail doesn't sit flat need to check their rifle. The rail is quality! Pros: Fit perfect, good hardware included Cons: None at all.
Most Recent Review Best scope base. by Legacy Reviewer, December 20, 2013
