Friend gave a . i77 telly air rifle and i figure out how to put cheap red dot hawk scope on it. will this scope last on a not to power full springer.What i like about this gun is that its very quite for in town. I have purple martin house and a pellet gun is a must for sparrows It not along range gun but dose the trick for short rang. I know for powerful spring cheap scopes don't last .My 2240 sounds like cannon compared to this telly. thanks ted
