I'm not touching mine until she's due a service, its unbelievably good out the box, was out doing a bit of practice on the range and I'm using a hawke hd 4-12x50 fixed objective scope combo, I shit you not...65 yard, 35mm spinner...all day long! Reckon I could do further too! Might post a vid on youtube to see how effective the accuracy is out to 60,70 and 80 yards :-)
