My friend and I are building carbines. How is the barrel measured? Off the weapon from one end to the other with the suppressor? Or not counting the suppressor? He has a old post ban bushmaster barrel that we cut the permanent flash suppressor off of. His barrel is 15" to the end of the threads with the threads being a half an inch. So if he buys a 1.5" suppressor and screws it on, is it legal? Or only if its permanently attached? Then I am buying a new barrel. If a vendor states its 16", is it 16" plus a suppressor (like 17" over all), or 16" over all? We ask this of course because we both want the shortest legal length. We appreciate any help. |

Barrel has to be 16" overal length. If it says 16" barrel and has a flash hider on it then it will be about an inch longer. If it is a 14.5" (or 15 inch; whatever your friends is) then the flash hider has to be permently attached. If your trying to get the shortest legal barrel than that would probably be a 14.5" with a permently attached FH . But you will only save a half an inch to inch which really isnt that big of a deal when it comes down to it. |

barrel length is measured with the barrel in the weapon with the bolt closed. Measure from the face of the bolt to the end of the threads if it has a removable flash hider. IF the measurement is below 16 inches you have an unregistered NFA weapon. IF you measure and have a measurement of over 16 inches then you have no worries. Places that sell a 16 inch barrel with a removable flash hider will be 16 plus inches to the end of the threads/crown of the muzzle. |
