I recently purchased a TruGlo red/green 4 reticle sight to put on my S&W 22A. I like the size and all but the 2 dot reticles have like a double image. The sight came with a large and a small allen wrench. The large one is for mounting and windage/elevation changes. I don't have a clue(no instructions) what the small one is for. I have emailed truglo but no response yet.
Could this wrench be for adjusting the focus?
