I would like to replace the band/pouch on my Marksman Maxima. I've had it since I was a kid, and I want to use it with my son. I am not sure how long or what size of band to get. Can someone assist me?

However, if you want to put flats on it, an 8-9" band will do better, maybe even doubles. I used to chunk pieces of wheel weights with it with the tubes that came on it. Good Stuff!
I'm sure you and your son will have great times shooting together.
