Yes, the SCAR 14" barrel assembly is exactly 14" from the bolt face, not 14.5" like most all AR barrels. You have to be careful when picking a muzzle device so that it adds at least 2" to the barrel so you're still over 16" when its pinned. With the SF SOCOM brake, the brake covers 1/2" of threads on the barrel so that brings the total length to 16.2". There are other muzzle devices out there that work, it just so happened that I planned on running a Surefire SOCOM and their brake worked perfectly.
