I know bsa aren't the best scopes available because I have 3 of them. But this sweet 17 6-18x is very flimsy feeling. If you want target turrets do NOT get this scope. These turrets don't lock, take very little effort to adjust, and stick way out which makes them prone to losing zero. spend another $100 on a weaver is what I've learned. You wont need 18x with a weaver cause the optical quality is far superior to bsa. I did not even see how accurate the calibrated turrets were cause after mounting the scope I tried to find something good about the scope, but just couldn't. So I have boxed up the scope and will be exchanging for the weaver classic rimfire for my savage 93 17hmr.
Pros: calibrated elevation turret for 17 hmr
Cons: turrets do not lock and stick out which makes them very prone to losing zero
