I could use a little help, I need an opinion on the pro staff series 4X fixed power scope. I'd be putting it on my Knight Disc Rifle. Thanks for the help.

I can't speak for the fixed power Prostaff, but I've got a 3-9X40 ProStaff on my Encore BP rifle barrel its been a great scope so far. Its taken some pretty rough rides on the atv and held zero perfectly and also is very clear and bright in low light conditions. I got mine on sale for $160 and its been worth every penny.
