You get what you pay for - Barska 6-24X50 IR Sniper Scope

First off I think I got a used scope. When I pulled the altitude dial off to set zero the first time it looked like someone took a pair of pliers to the actual inner shaft and started shearing off aluminum. At the price it wasn't worth the hassle and aggravation to ship it back as I would get stuck with shipping costs most likely.
I purchased this "value" scope as something with high power to slap on an AR15 for target shooting out to a few hundred yards. It mounted up fine and holds zero fine... IF... and a BIG IF... You don't turn the windage and elevation dials AT ALL. The clicks are not consistent, and clicking back to zero does not happen reliably if you go very far from zero. 24x power is dark, and a small sweet spot to acquire target at high magnification. I just sent about 500 rounds downrange using "kentucky windage" for drop and wind and it held zero great.
Parallax knob works well, and holds zero fine throughout the entire magnification range.
Pros: Price
Cons: adjustment knobs pretty useless
