Troy Medieval Brake and Barrel Length

I have a 14.5" barrel with a perm.-attached A2 style flash hider currently, and I’m looking to get another flash hider. I’m considering Troy’s Medieval flash hider, but I’m unsure if it’s long enough to stay within the 16" minimum legal length. If anyone knows… I’d appreciate your input, thanks.

it is long enough to give you 16 OAL
