I do not know where you are going to get a 4-12 power for that kind of money. I just mounted a Sightron I on my muzzleloader and it is a 3-9x40 and do far I am very impressed overall with the scope. Their guarantee is simple enough, if it breaks they replace it. It was only $119.00 and I intend on shooting the devil out of it.

Years ago Tasco was a good quality scope. I actually have two of the old World Class 3-9x40 on a couple rifles and they have held true and clear for the last 20 years.
