AR15 Mount Advice

[pfxsys]

I have a Rock River Arms Varmint A4 on the way, similar to the one in the following review:-

http://www.snipercentral.com/rra.htm

I am having difficulty finding the exact manufacturer / type / model of the mount. Then I need to find a Canadian supplier for this mount. Any ideas on both counts?

Initially I have a Bushnell Trophy 6-18 x 40 AO to go on the rifle, but next year I will invest in a medium/long range tactical scope.

The intended use is a medium to long range target rifle, if anyone feels there is a better mount for this purpose, please feel free to voice your opinion.

That looks like the Armalite 1 piece mount. Available in 1" and 30mm. I've got one and it's a good mount for a reasonable price.

how about the one from Larue? Not exactly the same, but suppose to be pretty solid.
