| I have a chance to buy a cheap 14.5" upper. This gun will be a beater/truck gun. If I attach the extended A2 can I just tack weld the hider to the barrel? will this meet the permanent attached requirement? |

A muzzle device, such as a muzzle brake or barrel extension, which
is attached to a barrel by means of welding or high temperature silver solder having a melting point of at least 1,100 degrees Fahrenheit, is considered to be part of the barrel for purposes of measurement. A seam weld extending at least one-half the circumference of the barrel or four equidistant tack welds around the circumference of the barrel are adequate for this purpose. http://www.titleii.com/bardwell/atf_letter40.txt |

Quoted:
Better off using a method the ATF accepts (blind pin and weld or silver solder). Small tack weld could come lose. Welding is absolutely an accepted method of attachment. In fact it was included on the list from a long ago letter; blind pin and weld was NOT on that list. Tack welds were specified as four tacks equidistant around the circumference. |

I thought I had read that somewhere. |

I mean none of this sarcastically. Just explaining my own thinking. From the ATF NFA handbook, page 6, section 2.1.3, Rifle: https://www.atf.gov/sites/default/files/assets/pdf-files/atf-p-5320-8.pdf "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." I've seen the letter from www.titleii.com many times before. I don't doubt it's authenticity but I've never been able to find that letter on ATF's site and I've never called ATF to verify it myself personally. I've also never been able to find tack weld documentation when I search ATF's website for "tack weld", "spot weld", "equidistant" or "four equidistant". I also don't know if the ATF's official position has changed since that letter was written 15 years ago. Those are too many assumptions for me to make when dealing with up to 10 years and $250,000. I just prefer making my decisions from what's in ATF's current handbook, downloaded directly from their site. If I ever found myself in a legal situation I don't want to hand my lawyer an unsigned, partially redacted letter from a third party website. If I could find the original it'd have more validity for me but I'd still default my decisions to today's handbook. YMMV |

Sec 2.5 - 2009 For example, a shotgun with a barrel length of 15 inches is an NFA weapon. If the 15- inch barrel is removed and disposed of, the remaining firearm is not subject to the NFA because it has no barrel. Likewise, if the 15 inch barrel is modified by permanently attaching an extension such that the barrel length is at least 18 inches and the overall length of the weapon is at least 26 inches, the modified firearm is not subject to the NFA. NOTE: an acceptable method for permanently installing a barrel extension is by gas or electric steel seam welding or the use of high temperature silver solder having a flow point of 1100 degrees Fahrenheit. https://www.atf.gov/sites/default/files/assets/pdf-files/atf-p-5320-8.pdf Better? You're arguing that the Atf hasn't specified what way to weld it? Both the section you linked, and I link, say welding is acceptable. |

I agree seam welding is ATF accepted (the quote I posted above mentioned seam welding too). It's tack welding I've never been able to find. |

But the tack weld is acceptable to import a handgun?
Case in point, the Zastava PAP, which has a thread protector tack welded on, so that it can be imported as a non-threaded barrel firearm. You have to break the tack, file/grind, and then you can install the proper krink brake. |

Perm attach brake relates to NFA, while tack welded pistol brake relates to 922r and import regs. |
