Nice scope - Burris Xtreme Tactical 8-40x50mm 34 mm Tube First Focal Plane (FFP) Rifle Scope

Clear optics, nice retical,first focal plane is different but seems good, beware this is a 34mm oddball diameter tube so you need 34mm rings, I bought the 140.00 dollar burris extreme tactical 6 screw steel rings and they would not hold the scope in place, it kept sliding forward on my 308 rifle recoil, now I'm looking for ways to make this work, burris says I mite have to spend another 129.00 dollars on 34mm signature rings with inserts just to hold it in place, because they do not recommend that I try lapping the rings that I have.
Maybe you will get lucky with rings that will hold this in place with strong recoil.
