Aim sports 2-7x42 scout scope (mil-dot reticle, non-illuminated) - AIM Sports Inc 2-7x42mm 30mm Tube Scout Scope

Bought this for my Soviet 1943 Mosin-Nagant, installed on an inexpensive rear site mount kit with cantilever rails, had some trouble with the elevation & windage adjustment dials (they would click but the actual adjustments were erratic). Eventually sighted the rifle in at 200yds but after 40+ rounds, the elevation turret completely stopped working (clicking but no reticle movement). Will return for exchange hoping that it just was a lemon (the long eye relief is great although 200yds is pushing the parallax limits of this inexpensive scope).
