very good scope for a low price. the sight is crystal clear, and it has a great zoom and line of sight. Contrary to popular belief, the zoom on this scope is very useful for airsoft. You will never need that much zoom for shooting, but many times I had to zoom to 9x to tell if someone was friendly or hostile, and it helped a lot with spotting enemies hiding in srubbery or whatnot. The only problem I had with this scope is the zeroing mechanism. It has an arrow pointing one direction that is labeled "left, one click = 1/4" at 1000yds ---_". You would think that twisting the knob that ----_ way would move the crosshairs left, but instead, it moves it right. it means you twist it that way if you are shooting to the left of the crosshairs. It is the same for the up/down knob. It never zeroed correctly on my M4 either, it still shoots 2-3 minutes left.
+high quality lenses
+good line of sight
+optical lense is a beautiful orange/red color. shows up crystal clear in the scope though.
-difficult to zero
-never zeroed correctly
-lense covers tint it to an unpleasent green color, easy cheap replacement
