Thread: Barrel length vs suppressor length

Obviously there’s a velocity difference, but not a consideration at this stage. Just the noise

An extra inch of suppressor provides significantly more sound reduction than an extra inch of barrel. For example, 7 baffles on an 18-inch barrel ends up about the same overall length as 4 baffles on a 20-inch barrel — but the 7-baffle setup will be noticeably quieter.
