14.5” Barrel question for a build

[dhnut1973]

I am planning to build an upper and I’m currently acquiring the parts needed. I want to go with a 14.5” non-NFA barrel. Can I purchase a 14.5 barrel, then later buy and assemble the rail, gas block and barrel nut before pinning & welding the FH on? Would I be in violation of the NFA if the bbl is not mounted to an upper receiver? I checked the NFA rule book, but I couldn’t find the info I’m looking for. Thanks.

An upper receiver with a short barrel is NOT a firearm. Having said that I wouldn't recommend driving around with a short barreled upper and complete lower in the trunk of your car.

There are no restrictions on your upper. You can have an 11.5 upper. A 12.5 upper. As long as they aren't attached to a lower you're fine. You can get in trouble for intent to build an sbr if you aren't careful.

As said, you are fine. Just dont install the completed upper on your lower until pinned/welded.

If you really want to be overly cautious, dont assemble the upper until pinned, but that is “above and beyond” the legal requirements.

Thanks for all the info and it supports what I was thinking. Just to be safe, as recommended, I have no intention of installing the bbl until it’s built and the FH is pinned and welded. Thanks again fellas.

I'm not a lawyer (of course) but I believe that if you have an upper with a barrel under 16" AND a lower in your house, some overzealous prosecutor could charge you with constructive possession. I've always herd that if you have a way to assemble things that isn't illegal, you should be ok. If you have 1 lower, 1 < 16" upper, and 1 >= 16" upper or you had 2 lowers, 1 < 16" upper, and 1 >= 16" upper you'd be ok. But if you only had 1 lower and 1 <16" upper.... it's not something I'd want to test.

Put a pistol buffer tube on for the time being to test everything out in case you want to change something out later. Pin it when you are completely satisfied with the build.

Correct me if I'm wrong, but as long as a buttstock isn't attached to the receiver extension, the firearm is considered a pistol correct?

I do not think that is correct. Removing my buttstock does not change my rifle into a pistol, legally speaking.

dhnut1973, take a look at this adjustable brace from SB Tactical. I personally dont like braces but this may help you with your build.
