You could easily have a .260 Remington hunting upper, and a 5.56 defense lower.
Am I reading this right? The 260 is based off a 308 or am I missing something?
what I was telling Bob, was that you can have two or more different calibers working off one lower. To have the .260 upper would mean using a .308 lower of course.
I was not clear on that, obviously. I should have used a 6.8mm or .204 Ruger upper in the case that he would want a common upper with a 5.56 lower.
