How does one convert an A3 to A4 ????

Thanks Rbruce,
It may take me a while, but if I do this, I think I'll try to stay with the redfield mount.

One ? I have, is the redfield mount centered on top of the receiver? Was wondering about the effect of ejecting spent casings.

The Redfleld mount is essential if you are building with an eye to competing in the CMP Vintage Sniper Matches.
No problem with fired cases clearing the scope base or scope.

Regards,
Jim
