Super Sniper 30mm rings

Anybody have any experience with these rings? They look like the Burris Xtreme Tactical rings.

I have a set going on my .308 tactical build. Built like a tank. The inserts to convert it to 1" are aluminum as well. That's a good price, too.

I ordered them yesterday. I had to call and ask them twice if it was for 1 ring or 2 rings, both times they said 2. That is a really good price. I hope they fit well on my F-class gun.

I've got a set that i've had for about a year. Zero problems. Good solid rings, very similar to the Burris xtr's.
