Seeking See-Through Scope Rings purchasing advice:

I have a DS Arms FAL with a DS Arms Extreme Duty Scope Mount. I would like to mount my Aimpoint 5000 2x onto it. But I still want to be able to use the iron sights.
Therefore I need See-Through Scope Rings that:
· will fit onto a 1913 picatinny weaver rail
· are able to take the recoil of a .308.
· and are 30mm in size.

Where can I find the best quality (and for the best price) See-Through Scope Rings?

Please respond in detail.

Thank you,
FRIZ
