A longer barrel has more velocity. But a 16 inch 300 BLK barrel already is sucking the juice out of the cartridge as much as a 5.56mm does with a 24 inch barrel.

So if you are the type of person who wants a longer-than-24 inch 5.56mm barrel, then you would also want a longer than 16 inch 300 BLK barrel.
