I have a 6-18x40 silver series. It needs a little better coating on the ocular lens. It has some flare and glare, but overall a great scope for my 17m2 H&R. Also have a 6-24x44 gold series on my 308 that seems like a great scope for the $$ I paid, which I think was around 140. The gold series is supposed to have coil springs that tension the adjustments, they are supposed to be more repeatable. Don't know for sure, just sighted it in and it has held it's settings.
