Rogy, As a less expensive alternative, but great quality, check out www.warnescopemounts.com
Look at their Optima Ultra High vertically split rings. They will place the scope at the same height as the original A2 aperature. They are quick detach, all steel, easy to mount, and return to zero.
The best price was at www.lockstock.com but you'll have to call them because these aren't in the catalog. About $45. Compare to Brownells at over $120.
GI Brat has a great set-up, but big money.
