| when registering and SBR with the ATF does the muzzle device count as part of the barrel lenght? |
| For the overall length I just measure from the muzzle device to the end of the stock fully extended. For just the barrel length only measure the barrel with no muzzle device. For instance I have an 11.5" barrel SBR with an overall length of 31". You don't have to be exact with your numbers though, as long as it's within an inch you are good to go. |

OAL and barrel length are both measured with any non-permanent muzzle devices removed. |

I believe OAL is measured with the stock collapsed and including the non-permanent or permanent flash hider. edited to remove incorrect info |

For a title I firearm, can a shotgun or rifle be less than 26" in length with the stock folded or collapsed? |

Unfold or extend the stock and that is when you get out the tape measure .. not before. |

I'm sure an ATF agent will taken out his measuring tape on your registered SBR to make sure it is within 1/2" of what you put on the form. Thank you for your most insightful post. The OP wanted to know the CORRECT way to take the measurement and that is what is being discussed here. |

Under federal law, a long gun is measured with the stock in the unfolded/fully extended position, because rifles and shotguns are defined as firearms "designed to be fired from the shoulder." ATF took this position for consistency's sake, because some folding firearms cannot be fired when folded and some can. Rather than test an example of each and every maker, they went back to the definition.
Note that some states differ from federal law, and measure with the stock folded or collapsed. In these cases, a single firearm may be a Title 1 (non-NFA) firearm under federal law, yet be classed under state law as an SBR of SBS. So check you state laws. As noted, barrel length and overall length are both measured with any removable muzzle devices off the firearm. |

Here it is right from the BATF NFA Handbook. Just so there is no question. Confused yet? The two statements in the handbook concerning overall length seem to contradict one another. "Extreme ends" to me indicates that the removable flash-hider should be installed and included in the measurement, while "muzzle of the barrel" in the other statement indicates to me that the removable flash-hider should be removed for the measurement.
The overall length of a firearm is the distance between the muzzle of the barrel and the rearmost portion of the weapon measured on a line parallel to the axis of the bore. The overall length of a weapon made from a shotgun or rifle is the distance between the extreme ends of the weapon measured along a line parallel to the center line of the bore. The ATF procedure for measuring barrel length is to measure from the closed bolt (or breech-face) to the furthermost end of the barrel or permanently attached muzzle device. Permanent methods of attachment include full-fusion gas or electric steel-seam welding, high-temperature (1100°F) silver soldering, or blind pinning with the pin head welded over. Barrels are measured by inserting a dowel rod into the barrel until the rod stops against the bolt or breech-face. The rod is then marked at the furthermost end of the barrel or permanently attached muzzle device, withdrawn from the barrel, and measured. |
