Brent,
The inserts were broke when I opened the rings, they had cracked and gone to hell while I was useing the rifle. I actually put the pieces carefully back together, cranked down the tops and kept shooting the rifle until I could get some replacements. I really like the inserts, wish they were in all rings.
Have also had some nasty experiences with Burris rings that did not have the inserts, worst scope ring cuts I have done was with Burris rings into a Burris scope on a one-piece Burris base. Win some and lose some.
