Give me the M70 and the Leupold as the lowest end optic and even then I feel like I'm taking a chance with the variables, which I used to hold in high regard but have broken enough through shooting that I am something of a carping skeptic anymore.
Like Ross Seyfried once said I regard Leopold variables about like a three toed coyote circles a piece of "free" meat on the side of the road.
Neither the Ruger nor the Tasco rise to any level of conscious stream of thought.....despite their virtues. I would not take either if you paid me. Life is too short.
