Not bad at all. - Barska 1x20mm IR Red Dot Sight w/ 2 MOA IR Reticle

I'm not sure if it's a quality control issue at barska, but I picked this little guy up used. I put it on my mosin nagant for a brush hunting rifle, and it held up to 50 rounds without losing zero. I could see the dot just fine during the peak of a sunny day. It's not a precision 2 moa dot like advertised. Closer to a 3-4 moa dot,and the rear lens fades out colors a bit, but I payed 30 bucks for the darn thing so I'm not complaining. I think it's well worth it's value if it works right.
