I've had two, about 5 years apart and as far as model i'm pretty sure that they were identical (6-24x42 AO). bought both for the same reason, hit a pinch in the "project budget" and could either afford the scope i wanted and little to no ammo, or some ammo + the Barska scope, and i like to shoot, not have my guns sit in the safe.
First one i never had any trouble with, clear, tracked well, plenty of adjustment (i used it to shoot my first 600yrd match) etc. So if you'd asked me about them back in January, before i bought #2, i'd have said to go ahead adn try one.
the second one barely lasted long enough to use up my inital batch of 200rds of ammo!
at about 140rds it would no longer focus below 20x and then the last time i took it out something broke loose/went wrong with the Elevation adjustment. I ran out of available elevation trying to dial in a 4" correction at 100yrds!:banghead:
so no i will no longer be telling anyone they should try Barska, b/c i don't want anyone to run the risk of having the experience i did with my second one.
