The RRA site says the CC has a 16" barrel with the smith vortex flash hider. Is the barrel 16" before the flash hider, or total length with it? Are they difficult to remove? I'm looking to get either a CC or PP, but I'm trying to figure out what the true barrel length are on the CC's. The flash hider is of no interest to me. Would rather take it off as long as it doesn't cause me to be illegal. I don't want any additional length if it doesn't benefit the shot.
