Uncle Ethan if you have a bull barrel installed the gas block will have to be drilled out to fit the larger barrel, or install a new heavy duty gas block. Shilen makes a bull barrel, which is only inlarged from the gas block on. Your stock will have to be inletted, or a new stock, to acomodate the larger barrel. You can do a search and enter "bull barrel", or "shilen" for key words, many posts will come up on this subject.
