Just like when you bought your suppressor you had to wait for the stamp before you could take it home.

There is a form to fill out and send to the ATF if your moving to another state.

You can have different length uppers for your registered lower, as long as you can transform it back to the specs listed on the forms.
Some people think this means you need to keep a 10.5" (in your case) upper/barrel at all times.
Others think you dont need to posses that original barrel length at all times.

I just got off the phone with the ATF "specialist" I was transferred to:

Can have multiple uppers for the SBR'ed lower.

Must send in a form, but don't need confirmation/permission (although it will be provided), can attach different upper(s) to SBR'ed lower as soon as letter is mailed.

The letter must contain: Caliber, barrel length, OAL, etc. just like the Form 4 for each upper I plan to run on the SBR'ed lower.

*I think you thought I meant can I put a <16.1" upper on a non SBR'ed lower. I meant can I change uppers on an already SBR'ed lower. I was not clear, and can see how it read.

Standard action spring and H2 buffer.
The 9mm "buffer" is actually more of just a weight for the blowback operation, it is not a good buffer and I would not use one on a 5.56. It is not heavier than the H3, but cheaper.

Increased extractor tension, heavy buffers. The same problems existed with a 14.5" at that time, the shorter barrel just magnified them.

I have 2 FA556-212's, though. One for shooting, one for looking at.

I was indeed looking at a switch-block version. I would need the VIS/MUR to clear the Surefire suppressor properly, though, as the Noveske rail doesn't do so hot for the SF product because of the little nub on the top of the rail.

My understanding (from silencertalk forums and talking to AAC in my case) concurs with what you stated above. I just go with the brake as I figure if I can save wear and tear on the suppressor with a brake of some sorts, why not? Although you do have the luxury of having a spare too!

just making sure i'm reading this right, the "specialist" told you that you could attach an SBR upper to the lower as soon as you send in your paperwork rather than waiting the 5-7 months to recieve your form 1 back?

if that IS what you are saying I would call again to verify. because unless I've been under a rock upper and lower cannot ever attach until you get your stamped form 1 back.

Sounds like he already has a SBRed lower, since he has a 12.5" already. He doesn't need to re-register it on a Form 1.

You need to read more carefully. He stated that you can change uppers on an already SBR'd lower as soon as you send the letter to the ATF advising them you are going to do so. How in the world did you misread that so grossly that you though he was stating that you could manufacture an SBR without an approved Form 1!?!

**davidjinks** · 08-09-12, 16:33

OP

A little clarification if you would please:

Are you asking in regards to a permanent change in length for your SBR? I.E. 12.5" to 10.5" permanently.

I was under the impression that you could attach any length upper to a SBR'ed lower and use it in whatever length configuration you wanted without submitting any new forms. The only time you submit a change in length is if it is permanent.

Anyone who is more versed on this I would appreciate clarification. I just went through this myself and was informed only if it's a perm change in barrel length.

The ATF requests you notify them of a permanent change to an NFA weapon. You can use different length and caliber uppers without needing any paperwork.

I didn't see where he was modifying an existing sbr therefore didn't know if he was talking about shortening an existing registured SBR or building another complete setup

Thank you Todd. I know I read it from an ATF link after being informed by my examiner.

Much appreciated!
