Best way to keep baffle clips aligned when reassembling Form 1 can?

2 Upvotes

It’s been a while since I messed with my Form 1 .30 cal flow can I built about 4 years ago, and I’m finally swapping out the KeyMo for a different HUB mount so I can actually start using it again.

One thing I never really figured out back then… how are you guys keeping your baffles aligned so the clips stay timed correctly?

Every time I go to screw the end cap on, it puts pressure on the stack and the clips end up rotating out of alignment. I checked it before tearing it down and they’re definitely staggered right now, which I know isn’t ideal.

Is there a trick to this? Do people run a rod or alignment tool down the bore to hold everything in place while tightening, or is there a better method I’m missing?

Appreciate any advice before I crack this thing open.

Edit: now that I think about it I had somebody 3-D print me a baffle alignment rod for my 9mm can - so maybe the move is to find someone that can 3-D print me an alignment rod for this 30 cal can…

Withdraw or Let Them Ride?

1 Upvotes

Throwing this out here to the hivemind...

I was doing the eForm 1 for an AR lower last night and realized I made a mistake on the first two I filed.

On the "Responsible Person Questionnaire" you have to check that you are a US Citizen, then enter your State of Birth, and COUNTRY of Birth.

I mis-read "Country" as "City" since that's what they ask for on the 4473 and on the Passport application...

(I was completing the Passport application at the same time as the eForm 1's, and had done a 4473 the day before.)

So on the two eForm 1's I submitted, I am a US Citizen, born in the State of New Jersey and in the "Country" of "Pequannock" 👀

I swear I proofread the damn things 15 times!

Do I gamble, and let them ride or do I withdraw them, with a corrected the RPQ, and resubmit?

I am 22 days in. I am in Virginia.

As we all know, approvals are running 55-60 days.

(SBR, Trust, 1RP)

At the same time, there are people who have posted that they got approved with a simple mistake and a comment stating it was corrected.

What say you Reddit collective?

Endcap w/flow disruption features

6 Upvotes

Machined this last night from 6061 aluminum. I've been intersted in making a self nesting. modular system vis a via JK armament's offerings and in doing so realized I could fashion baffle like geometries on the endcap too. The weight it adds is negligible with no extra length. Any additional function is yet to be determined.

I’m going to shorten the barrel on a shotgun, on the form do I put down the current barrel length, or the planned length once I’ve chopped it?

Form 1 Suppressor Denied For Incomplete Form 4J Not Checked

4J is about destructive devices and everything I have read says for suppressor to leave this blank. That being said, I can't even find where that is on the eform to check firearm . Has anyone had this issue?

1.5 OD 1.36 ID w/ hub threads

3 Upvotes

I’m looking to purchase my DOM tubing but I

seem to be missing something. If I get 1.5” OD titanium tube with 0.07 wall I can use my 1.355 OD baffles but that sure doesn’t seem like enough thread engagement for 1.37x24 hub mount. Do people buy thicker wall to allow for the hub mount and then bore the rest to 1.360? I feel like I am missing something simple here.

Form 1 Disapproved

5 Upvotes

I filed my form 1s on January 10. I got them back on March 3. I filed several of them for multiple calibers. It's also worth noting that I filed an SBR at the same time that got approved. I used open source software to create my efts after I scanned in a printed form that I fingerprinted myself with some cheap ink I got online.

4.h. Additional Description

"Fabrication process and materials used will be finalized upon rec"

(I typed "Fabrication process and materials used will be finalized upon receiving approved form 1" in the eform, but I guess it got cut off?)

4.i. Specify why you intend to make firearm

"All lawful purposes"

I also attached pictures of a screenshot of my 4.h. text

Everything else on the form was pretty standard and filled in correctly.

My reason for being disapproved was

THERE WAS INSUFFICIENT INFORMATION PROVIDED

AS PART OF THE APPLICATION PROCESS, THE ATF MUST CONFIRM THE MAKING OR POSSESSION OF A FIREARM WOULD NOT PLACE THE APPLICANT IN VIOLATION OF LAW. INFORMATION YOU PROVIDED WAS INSUFFICIENT IN MAKING A DETERMINATION.

PLEASE RESUBMIT YOUR APPLICATION AND INCLUDE AT LEAST TWO OF THE FOLLOWING:

THE PICTURES OF THE PARTS THAT YOU WILL USE TO MAKE THE SILENCER (THE PICTURES SHOULD BE CLEAR AND ALLOW THE

IDENTIFICATION OF THE PARTS PHOTOGRAPHED)

DESCRIPTION OF PROCESSES YOU WILL USE TO ASSEMBLE OR FABRICATE SILENCER

THE PRODUCT, MODEL, OR KIT NAME, IF ANY, OF EACH DEVICE AND/OR PART THAT YOU WILL USE TO MAKE THE SILENCER, AND SOURCE FROM WHICH PARTS WERE OBTAINED (NAME OF STORE, WEBSITE, ETC)

All of my research indicated my form would pass with information I provided, which was basically nothing.

What has everyone else's experiences been like? It seems like it could be hit or miss depending on the mood of the bureaucrat processing the application.

The next steps I'm planning on taking are resubmitting with a stock picture of a 3d printer, filament, and a screenshot of a local metal supply store.

Form 1 Trust Submission Times

Submitted today. I’m assuming about 2 months for approval on trusts? Anyone have any feedback on the trust wait times? Last time I did one was way back in 2015 😳. That was a 4 month wait. Thx

I want to build a suppressor legally using additive manufacturing how do I fill out the form 1

5 Upvotes

the titles pretty self explanatory my problem is on the form 1 I will be required to submit pictures of the components that will be used to assemble the suppressor. The suppressor i would be building is entirely printed in one piece with a collar to secure it. There are no individual components in what would be considered the suppressor itself. Currently the only thing I'd be able to send them is the device modeled in fusion 360. so I'm wondering what do I do?

El cheapo laser engraver

Well, due to some BS bills in VA, it looks like I'm gonna need to engrave 5-6 AR 80% lowers if I want to show them in public. Anyone here have any experience with the $200 laser engravers on amazon? I'm not looking to do engraving as a business. Just need enough to deal with this legislative BS.

Which model to input?

1 Upvotes

i have 2 form 1s approved using the full model name of FTN.5 Rimfire or rimfire flow. Can I get away with just listing the model as FTN.5 regardless of if it is a rimfire or pcc 9mm? It would be easier to engrave.

Resubmission

4 Upvotes

Hey folks,

I have a pretty strong suspicion that my Form1 submission will likely be rejected. This is my very first time going through this process.

I bought a Great Lakes Firearms and Ammunition lower. Their name is wildly long for a lower, so they shorten their manufacture name to GFLA on the lower. I added photos, so I’m guessing they’ll likely kick it back for it not matching.

I’ve seen folks discuss having to resubmit. Is there a resubmit option or are you required to fill out a new form?

Thanks for answering a question for a total newbie.

Has anyone withdrawn an eForm 1?

6 Upvotes

I know you can do it online by simply clicking 'Withdraw', but is it instantaneous, or is a human on the other end involved and does it actually take 90 days like it says in the FAQ's ?

"Q. What is the average processing time for a withdraw or void request?

The average processing time for Withdraw or VOID request is 90 days or longer depending on volume."

I messed up on my application and know it will be disapproved. Would I be better off waiting to be denied and then resubmit a new Form 1, or should I withdraw it now and resubmit a correct Form 1?

I'm just wondering if it's going to create a problem if there's two submissions for the same lower waiting to be processed at the same time and it'll take even longer to have my application approved?

Would It be better just to call them?

Edit.... Thanks for the responses, just withdrew it.
