Sorry to break into this political forum with an Airgun question but life had to return to normal eventually. I lent a pal a Gamo with a Tasco 4 X 40 scope on it. He's been struggling to sight it in vertically but has found that it's run out of travel with metal fragments aplenty. This is only the second scope I've ever owned so would welcome any advice. Is it worth attempting a repair, sending it for repair or simply scrapping it?

ATB, Mick
