I got my SBR stamp a couple months ago for a 300 build i was doing. Now, i would like to rebarrel one of my 5.56's to a 12.5, question is, can i have an upper chambered in 5.56 on my registered SBR lower that's engraved as .300 cal?
i know you dont have to and the ATF only suggests to notify them of any change of caliber to a registered firearm, but can i have the 5.56 upper on even without the 300 upper with me? |

thats what i thought, thanks! stupid how they make you engrave the caliber on the lower if it doesn't matter then! I hope you didnt engrave a caliber on the lower because THAT IS NOT REQUIRED!!!! You are the "maker" and you engrave your name and location and at that is it. |

You are the "maker" and you engrave your name and location and at that is it. It's not required to be on the lower, but it's absolutely required on the completed firearm (can be lower, upper or barrel). So if the lower is marked "multi" (or a different caliber), and the upper/barrel isn't marked, you have to engrave it. But don't take my word on it: ATF Ruling 2013-3 Hodgi_...the issue is the making of the Form 1 firearm is a one-time action. That's why caliber, barrel length, etc all matter. Once that firearm is made, the current configuration doesn't matter. |

After the initial making......it doesnt really matter(at least with an AR since there isn't a "permanent configuration) Get whatever upper you want. |
| The one I have that wasn't marked ("multi" lower, lost barrel markings when it was cut/threaded) just has a simple "6.8mm" between the pivot pin ears on the lower. Visible without disassembly, but nobody will ever notice it. I used a Dremel, so $0 and <1 minute, but meets the letter of the law. |

it was an 80% lower i sbr'ed so i was under the impression there had to be a cal mark on it. i dont care if its marked 300 ther 5.56 upper will only be used when im doin carbine courses Yes. There has to be a caliber mark that matches what was applied for on your form 1. Once you have satisfied the form1 and built your sbr as applied for, you can do what you like with it with no obligation to notify the atf. Its an ar so its modular and does not have a permanent configuration. I thought you were asking if you need to re-engrave for a new upper. |

Wouldn't the manufacturer's marking on the barrel meet the letter of the law then? Quoted:
and certain additional information - the model (if designated), caliber/gauge, manufacturer/importer’s name, and place of origin - on the frame, receiver, or barrel. Wouldn't the manufacturer's marking on the barrel meet the letter of the law then? If its not covered up it would work fine. Nothing says it has to be close to the other engraving...right? |

You do need a serial number created and engraved, which isn't required if it was simply a Title I firearm. |

No need for it to be close to anything else. That's why the barrel works. Also why people engrave under the trigger guard, which is nowhere near the serial number or model. It's a rare occurrence for the maker to need to engrave the caliber because the majority of barrels are marked. The only one I've done is where I chopped a 16" barrel to 12" and lost the manufacturer markings. |

The only one I've done is where I chopped a 16" barrel to 12" and lost the manufacturer markings. which is exactly what i did, and therefore had to put a cal marking somewhere. i know where most people engrave that stuff to be hidden, but i had a guy engraving this for me pro bono so i made it easy for him and just had it all done on the mag well. it doesn't bother me, and its my rifle. |
