They have a very good product, specially the Fullfield II for the money. But their customer service is not that great. Actually one of the slowest of all the manufacturers.
I have a fullfield II and a signature series. ok scopes but i really think the leupold is a better scope. burris seams to not be as clear in low light or hazy, rainy days.
honestly my next scope will be a sightron. i think i will give one a try i have heard nothing bad about them.
