I have done a little research on optics for my very first rifle which is the Bushmaster XM-15 E2S. I dont want to spend a whole lot of money at first until I get into it more. So I was thinking about the Burris AR 332 for my first scope. I only want to shoot about 2-300 yards at first so what does everyone think? I would also like suggestions if that scope would not be a good fit for me
