How much louder than a 16" or 18"? Can you tell a noticeable difference?
On any given day I have guys with 10.5", 11", 14.5," 16", and 18" M4's. You can't really notice a differamce between 14.5 and 16 or 18" barrels. Having said that, they're all permanently damaging with but a single unprotected shot, so one being "quieter" doesn't really matter. There is a noticeable difference in blast between the 10.5 and 11" guns and the 14.5" and longer, but again they're ALL permanently damaging with a single round being fired.
