I recently bought a Beeman HW97k air rifle at club sale, and it came with this scope. I have found very little on this scope, other than it may be the predecessor to the Bushnell Trophy. It is a 6-18 AO. Interesting part is all the extra distance markers on the AO. What are they for? Airgun field target maybe? I found one post on another site that said Beeman may have sold some rifle combos with a Bushnell scope. Maybe this is one of them. Just looking to see if anyone here might know before I go asking on other sites. Its currently sitting on a BSA Martini 12/15 in 218 Bee. Merry Christmas.
