I know I'm new here and I hate to be "that guy" but please, don't do that. Don't use a barrel that's going to ballistically handicap a great round. The shortest I would (will) go on a Grendel is 18 inches. I feel the same about my 556s too. Even 16 seems too short. Then again, I'm 6'2 and 205lbs. Longer barrels fit me fine.
