LaRue Barrel Swap

[jpistolero02]

I just purchased a complete 6.5 Grendel from LaRue. I went ahead and ordered the 5.56 barrel and bolt to go with it. What's the difficulty of actually swapping the barrels on the rifle? I assume it's not something you just do all the time. My experience level with AR's is fairly low. I have owned one for years, but never built one from the ground up. Thanks in advance for the help.
