I was initially concerned about holding lateral postion, but after about 100 rounds (.223), it still seems steady and solid. This was a rifle-saver as the Rem 700 ADL had mis-aligned mounting holes drilled, so much that max scope adjustment (and there was PLENTY) wasn't sufficient to overcome the correction needed to zero the scope.
Pros: As advertised
Cons: None discovered
