I picked this up the other day and put it on my 10/22 and have to say that I'm pretty impressed. Locking and re-adjustable zero. 1/4moa per click. Decent eye relief. Snug caps. QD rings that are actually tight. Black mil dot reticule with red or green on a rheostat. Pretty compact little scope. Great accuracy so far as well. Anyone try one of these before? They hold up? Did I just waste $50 on a piece of junk?
