Chuck, mine doesn't have the firefly reticle but I have the Bushnell Elite 3200 2-7x32mm on my Marlin 336SS. I have to say that I'm really impressed with it. It's a 30-30 so I didn't feel a need for anything over 32mm, and it sits nice and low on the rifle. The glass is really clear and I can easily see a deer at max distance after shooting hours.
