SBR overall length question

[darkfader]

Can you guys help me out here? I want to form1 my AR pistols. They both have braces on them now, one has the SBA3, and the other has the SBA4. Both are adjustable as I'm sure you're all aware. Once legally stamped SBR's, they will get adjustable carbine style stocks. How does one measure the OAL of the rifle/pistol when filing the form1? Fully extended, completely collapsed, end of buffer tube without the brace? Thanks for any help.

I believe that you measure with it collapsed but, it's been awhile since I've done one. Would be interested if someone can post up the legal jargon on it.

Fully extended...if your muzzle brake is pinned include that in the length, if it's removable do not include it

Huskydriver is correct. (1) How to Measure the OAL (Overall Length ) of your SBR for your ATF Form – National Gun Trusts

I’ll jump on here with another related question if the OP doesn’t mind. I’m about to go down this path as well.

Question: How precise do the overall length and barrel length measurements need to be? Is plus/minus 1/8” ok? 1/4”?

Better to say it is shorter than it really is by a smidgen, than to say it is 17” oal and it be 15” imo.

Possibly a stupid question, but....,,,,,,
I recently filled out my first e-file for a Form 1 SBR. I put 10.5” for my barrel length as that is what I currently have. Will I be able to put a 12.50 upper or some other length on this lower in the future or am I stuck with 10.5?

From what I understand, if you make a change, you need to notify the ATF and eventually they contact you confirming your changes. I’m no lawyer though so better research to be sure. Keep some kind of proof you notified them, like an email or maybe a notarized letter. Again, this is just what I’ve read around the forums so I can’t really say for sure. If you try the ask the experts function on ATF webpage, you just get a response a week later with some FAQ’s. Pretty low end setup they have.

Defenitly want to double check that i have always heard you only have to notify about a "permanent change"

I.e you can switch uppers to a 12.5 upper as long as you still have the 10.5 upper and can convert it back.

Edit: Also am not a 2a lawyer dont take my word as gold.
