I searched around and couldn’t find the answer to this question; if it’s a doop I’m sorry.
Do you have to pin or weld a flash hider to a 14” barrel for it to be legal? 
|
| Most setups will need a 14.5 inch barrel with a permanently attached flash hider to be long enough. Any rifle with a barrel shorter than 16" is an SBR so for a standard A2 flash hider you will need a 14.7" barrel. You can buy a shorter barrel without any transfer taxes, you must permanently attach the flash hider before installation on the rifle. |

Quoted:
You need to register the lower to install it, and it's unwise to have it laying around the house until it is modified. Register as a SBR? What if I'm just building a new gun and a buy a brand new lower (transferred through a FFL as usual), a 14" barrel and I weld a flash hider on it that makes it 16" and put it all together am I GTG? |

There can be issues with possessing both a lower and a short barrel simultaneously. |
| simply put and hope this helps and clears it up for you. you do not have to do a nfa transfer for just a barrel or upper because you can asemble it as a pistol which does not have a length restriction, although you do not want to have an assembled upper and lower that can make one full sbr as this can land you in trouble with the atf. barrel length must be 16 inches from bolt face to end of barrel or permanently attached muzzle break of rifle. several companys make muzle brakes that ar 1.6 inchecs long that bring it out to 16.1 incheccs long (ex. is troy, vortex and some yhm). two ways accepted by atf is 1100 degree solder or pin and weld. |

Order lower for build, normal transfer through FFL 2. Have everything needed to assemble the upper EXCEPT for the barrel 3. Order the 14" barrel have it shipped straight to me no transfer or NFA tax or reregistration of any kind 4. As soon as I receive the barrel permanently attach the FH to to create a 16" end to end barrel 5. Put it on the lower and I'm GTG

A rifle with a barrel less than 16" long that is that has not been registered with the ATF is an unregistered SBR ... that's bad.
Permanently installing a flash hider on a short barrel makes the barrel 16" or longer which is legal. Being in possession of a short barrel (less than 16") AND a lower is bad. That is considered as being in possession of an unregistered SBR. Barrels, whether short or long are just parts and do not require paperwork of any kind. Barrels are just parts. You should not be in possession of both the barrel & lower or barrel & short upper. Every second you are in possession of both the short barrel and lower ... that's bad and you are susceptible to being busted when/if someone happened to raid your pad. You can construct an AR Pistol which is basically a SBR minus a stock (check your local laws). The lower should be transferred as "other" that way it is not a rifle or a pistol. You can make your pistol then when you get your NFA stuff done you can simply add a stock. If the lower is a "rifle" then it can never be legally made into a pistol. |

There can be issues with possessing both a lower and a short barrel simultaneously. It's a non-issue with an uninstalled barrel. A short barrel by itself is fine. An assembled short upper is where you can get in hot water. |

Nitpicking, but barrel length is measured from the closed bolt face to the end of the barrel, not the OAL of the barrel itself. A 14" barrel is going to be longer than 14" because: 1. The barrel extension adds a little length 2. The point where the bolt face would be is "inside" the barrel |

Barrel length is measured from bolt face to the last thread or bolt face to the end of muzzle treatment? Bolt face to end of FH = 16" = GTG? |

Is that "intent" to make it into a F/A? |

Quoted: Quoted: I'd do a registered SBR lower while you're building this gun. You're going to want a SBR someday––-just spend the extra $200 now and be ready for that 11.5" BCM you're going to want after Christmas  Where can I get the paper work to register a SBR?  http://www.atf.gov/forms/download/atf-f-5320-1.pdf That, plus $200 and a CLEO sign-off, or trust, or LLC, or S-Corp. |

There's no constuctive possession for SBRs Federally, some states (CA for example) do have constructive possession statues, so it depends on your state.
The BATFE measures the barrel length by dropping a 16" rod down the barrel on a closed bolt. If any of the rod sticks out beyond the barrel it is a short barrel. This is the end of the barrel itself without a permanent muzzle device or to the end of the permanently attached muzzle device when installed. |

Whats the best way to do it? I could get the sheriff to sign off no problem or do it in a Corp name, is one way better than the other? Thanks for the help here guys and the patients....
