If anyone has experience with the Sinclair gen II windage top I would like to know if the top has much play in the windage adjustment ? If I install this top on my Hart rest will it work well enough for me to compete in the local rimfire bench rest matches. Or would I be better off getting the complete competition rest when they become available again. Will be using a Anschutz 64 MPR that has proven itself to be a great grouping rifle. Thanks for the help gentlemen .
