Don’s Winchester 70 in .270 gets just under 1MOA with his handloads. It seemed appropriate to top it with a better scope than the scary optical contraption it had originally.
Just got another 1-4x scope mount. Can't beat it for the money. Given it's continued survival on my friend's .450 Marlin bolt gun, it should do just fine on 5.56/6.8/.308 AR15 types.
