I just bought my first .308 and now I'll need a scope for it. I'm looking to stay around 4x and up. I have a 3x primary arms on my 5.56 and love it. This may be a stupid question but can I use a .223/5.56 scope on it, I know the BDC will not be correct but I'm more interested whether or not it will hold up with the recoil of a .308. I'm looking to spend $400-$500 new or used.
