Took my Enfield out after the snow receded from my field. Not that it matters, but I began zeroing at 25 yards (bullseyes), but in moving back to 100 yds. I was low. What I found after not being able to move my elevation dial is that I need a very specific tool (looked on-line) which, I'll have to look for. I'm sure I'll find one
Optics are clear as a bell, and they are specific to the rifle. Anyway, just thought I'd post it to share.
