I just purchased my first airgun rated rifle scope, it's an Hammers 4-12x40 AO and yes...it's made in China but it's all I could afford so it's mounted on my HW50S and I will attempt to sight it in tomorrow if I get away from work in time. I'll let you know how that all goes and if it last I'll keep you guys in the loop on that also. I paid a few pennies under $100.00 dollars for it shipped two day air, there's a lot of reviews on these scopes...many good...some bad just like everything else reviewed on the internet. It seems well built and is of quality material...but time and use will determine just how well. Oh and it came with a one piece four bolt scope mount with a stop pin which worked well with the rifle.
