I have the Weaver Quad Locks on my Rem 700 .243 and they work great and look nice.
HOWEVER I did not like them on my Browning A-bolt
I would get something a little higher quality for the A-bolt. I would suggest you look at the Leupold PRW rings & QRW bases. Same style set up, except that they are steel and alot better quality. There is just no sence in spending that much on a gun & scope and using cheap rings. Get the PRWs rings
HERE and the QRW bases
