What good is accuracy if the bullet is traveling too slow to accomplish anything? At that barrel length, a 9mm SBR would be better.
How much velocity is lost when firing .556 from 7.5" barrel opposed to a 14.5" or 16" carbine? I know this will differ with ammo brand and quality. Just looking for some kind of average comparison.
