One thing to watch out for..Base screw that are too LONG! within the last month I have bought two sets of Warne M826 bases..one set for a Disc Elite and one set for a KRB7. On the KRB7..they just BARELY worked..almost too long. On Disc Elite...the screws WERE too long..so long the screws bottomed out and would not tighten..I could easily move the bases when the screws were "tight."
Just for fun..I took the M826 bases off the Disc Elite and tried the bases/screws from a new set of Weaver Grand Slam S45 bases..worked PERFECTLY. I was able to really tighten down these bases. I'm gonna leave these on there and get some lower rings..
