Bought this and mounted it on my center-fire BA rifle in .308Win. Took it to the range and it did ok. For the price, it's a great first scope. It did have a little trouble getting consistent groups at 100yards for me. Holding zero was a little difficult. My next scope purchase will probably be a nikon prostaff, though I realize the tasco is a third of the price. I used redfield medium scope rings and took it to the outdoor store to get it mounted (with lock tite on the screws) and bore-sighted too. As a basic intro scope, you'll be able to have some fun with this though and put a deer on the ground if that's what you're looking to do.
