I have to of the Crossfire scoped , the first one is a 4x12x44 I used it on a Ruger 30-06 for 4 years way over 100 rounds and now it is on my sons new Savage 30-06 about 50 round thru that gun still working great. I put a 6x24x50 on a Rem 700 in .300 win and it is rock solid ,the gun and scope shoots sub MOA all day long. Also note that for about 75 bucks you can get a custom turret for it from Kenton industries.
Just my views , I am on a budget with kids private school and now college start next fall.
Cant go wrong with Vortex.....
