I bought this for my Marlin 39 Lever action rifle. Fits the rifle fine and looks very good. Easy to zero and very accurate. Only problem is that it does not take much to knock off its zero. For example with the M39a is a take down rifle and to disassemble the rifle it takes a few good smacks to take it apart. That is enough to affect the zero. Other than that its pretty good.
Pros: Price, clarity, ease of set up
Cons: not rugged
