Solid construction - BSA Optics 42mm Red Dot Sight

Good solid finder scope with metal housing. I would have liked more variation on the low level intensity but it is still satisfactory. Using it as a finder scope for a telescope. Mistakenly thought the left/right and elevation controls were adjustable with thumbs screw but they are actually screw down dust cap covers for a flat head screws, so it will be interesting to see how easily I can adjust these in the dark.
