I am sure you will hear differing opinions. In my opinion, they are junk. You could not give one to me. I bought two of them several years back and sold them both for half the price of what I paid for them about a month later.
The ones I had would not hold zero. Maybe it was just a flaw in the ones that I had but it was enough for me to classify them as junk and never use one again.
I don't believe in cheap optics and in my mind that is what Barska is. You can have an awesome shooting gun that won't hit near its potential if you have cheap optics on it that don't do their job.
With that said, I don't think you have to go overboard with the optics. There are plenty of decent quality sopes out there in the $200.00 range.
Here is one differing opinion. I have 3 and think they are fine. I bought the first one just out of curiosity. It worked fine as an average hunting grade scope so I bought one for my chuck rifle. It holds zero fine, but like I say, it is an average grade scope. So depending on your needs and expectations, they may or may not be for you.
I have heard that guys that use them on rimfires and at most 22 Hornets they like them.. If you were going to put them on any gun the kicks more I would go to another scope.. They are probably the cheapest scopes that you can buy.
I did hear that the Barska Lazer sight is JUNK!!!!!
Would I personally buy one. NO! I like the cheap Muller illuminated 3 X 9 40 MM scopes for fox hunting and Muller's 4.5 X 14 AO for chucks...
