Range on Wednesday and I'm now a sworn member of the Larueminati. Tightened up the cams and got a 1.5 and a 1.25, 5 round groups at 100yds, Winchester white box ammo. Took the 608 off, fired a few rounds and put it back on. Same size groups. Three 1.25, one at 1" and one 1.75 with one round AWOL. The point of impact shifted about 1/4" left after replacing but not enough to move the scope; it was probably just my shooting. Take out the two freak groups and this is way better than my day with the Sage DCSB. I inked the rail and the 608 didn't budge; neither did the DCSB for that matter. This was 100 yds, so not a real distance test, but enough for me. My gun is a SA NM with a Surefire flash hider, scope is a Mark4, 4-14 in Badger rings. YMMV but for an EBR, I'm pleased.
