i have had 2 of them and they work good for me the glass is not that great but they are only $100. my freinds have had a couple for 6 or 8 years now and have never had a problem good scope for $100
I have a Banner on my remington 700 243,and my father has one as well on his savage 110 270 win both are 6-18x50 and we've had no issues, not sure about repeatability though if thats what you are looking for. Great scope for the money.
