Thanks for the feedback on the Briley handguard, guys.
Bill, many years ago I was a machinist apprentice, and knurling was one thing taught in the program. There was a lathe tool with two "wheels" that were serrated in opposite directions. Pressed against the rotating bar stock, it produced a knurled surface. I'd imagine AA used the same method to knurl that barrel.
Personally, I like the looks of the fluted barrel better. But, I suppose the knurled barrel could do double duty as sort of an oversize rat tail file...
