Never heard of it before, but if it's related to "Quigley Down Under", I'd like it!
Ok, you made me go look it up. Interesting with mixed reviews. None bad however that I found, but just reviews that liked it but didn't feel like the claims that it was special were justified. One comment was that they are "custom" scopes built with the etched retical specific to a caliber and load (down to the ballistic coefficient, muzzle velocity, weight bullet, etc.,) so it is chained to that setup for the duration. I'd consider one if the price was right.
Please stop back by here and give us a review if you don't mind. I'd like to hear your opinion.
