Who's done them? Wanna show off your cans? Any advice for a first timer as far as buying components, design, or the build process?

I've done 1, was a lot of fun for me - mostly the research aspect of it. You can get absolutely overwhelmed with the information out there, who does what, materials to choose from, etc.

My can is a Ti tube and end caps with stainless baffles. I've bounced between the individual M baffles and a single core monobaffle and frankly the M-baffles suppressed better for me. I would advise you to look into the simpler designs if you are doing a Form 1 for the first time unless you are an experience machinist or fabricator and have the time, equipment and materials to play around with.

You just missed out on starting a thread that would have received wayyyyy more attention

I've done two. Good cans, heavier than commercial, but they work well and are definitely cheaper. I bought most of my parts through SDTA.

Here is my write up from my Form 1 build I completed a few years back. Well worth the money spent.

https://texags.com/forums/34/topics/2667835

Been planning on doing another one day when I have some free time. Maybe sometime this year I will get it going. I need to get some decent pictures of the process to post since I will be machining everything from raw materials. Definitely one of the perks of being a machinist.

Thanks for starting this!

I'm gonna start my process mid Feb (Valentines gift to myself), and was going to start a thread very similar, but I'll just piggyback off yours.

Any guides out there to make sure that I properly fill out a form 1 e-file since the 41F ruling changed a few things?

Plan is for 30-cal can. Planning a maglite tube, with stainless baffles, and one of the shorty QD mounts from SDTA. Will be used on 7mm-08 bolt gun, and a couple 5.56 AR's.

Use one of their titanium tubes instead of a maglite. I wouldn't trust aluminum for a centerfire tube.

Be careful with aluminum tubes. Not as strong as steel or Ti, don't handle heat as well. Not nearly the issue on the 7-08, but can be on an AR where you can pump rounds out faster than you think.

I also like that you are going with a QD mount, well worth it from a barrel protection aspect, as well as the fact that the break/dissipator is integral to helping suppress on most designs.

I have the feeling that my first one will probably lead to more, so I was thinking of doing a Titanium 22 LR Form 1 with one of the Diversified Machine kits, so all I have to worry about is drilling and clipping the baffles

https://diversifiedmachine.us/product/select-titanium-kit/

OR, another option would be to piecemeal something together from SD Tactical and somebody else for the baffles.

Any experience with either of these?

I was planning on going the "storage cup" route, rather than freeze plugs and spacers, so the storage cup will have an integrated wall. My initial thought was that theses walls would be pressed together tight enough to bear the brunt of the pressure, and the aluminum tube would be more just to hold everything in alignment, but I see what y'all are saying.

The Ti tubes are cheap enough that it doesn't make sense to try and scrimp on that part.

Thanks for the advice.

Anybody use carbon fiber tubing as spacers (between the valve spring retainers) inside of titanium tubing? What is standard spacer material?

Status update on these. I'm going to document the process for anybody else that is interested in doing this in the future. I just submitted two eForm applications to the ATF this week--I'm going to build one for 22 LR and another in 7.62mm for my AR-10.

Steps taken so far:

1. Created a trust for each build.

2. Requested free FD-258 cards from the ATF, then drove down to HPD and got two sets of fingerprints for each build. Cost was $10 per card.

3. Created an online account with the ATF.

4. Submitted one application for each can via the ATF's eForm system, using these links as guides
ARFCOM
REDDIT
Form 5320.23 instructions

5. The form for my 22 can was marked SUBMITTED/IN PROCESS immediately by the ATF, so I printed the CLEO notification pages, mailed those to the State of Texas Prosecuting Attorney, then printed the cover page and mailed that along with two copies of my fingerprint cards in a USPS flat rate envelope with tracking and signature confirmation to the ATF. Fingerprints arrived at the ATF this morning (3/8/2019), and most Form 1's are being approved within 10-12 days of the date fingerprints arrive. We will see.

6.. The form for my 7.62mm can was marked PENDING RESEARCH. I think what happened is that I used named a model for my silencer, "FALCON" (I'm a former Corps of Cadets Falcon 16 Fighter), which is optional for Form 1 registration, and while that model existed in the system, nobody had made a 7.62mm version yet. Within two days, I received a notice that it had been revised in the system as SUBMITTED/IN PROCESS, so I could print the cover page and CLEO notice and mail those (separately) along with my fingerprint cards. So this can is probably 2 days behind the other.

7. Ordered a Select Titanium Kit from Diversified Machine. Dimensions are: 1.125 x 0.995 ; 6 inches long ; 1/2-28 threading. Price was $240.

8. More research needed on what I'm going to use to build the 7.62mm can.

So far, the process seems designed to keep law abiding citizens from exercising their 2nd amendment rights by making it overly complicated and expensive. Now I need to find a metal lathe. Anybody willing to help teach me and allow me some lathe time in exchange for money or beer or both?

I would be interested in your 7.62 build once you have an idea what direction you are going with it...

Why did you create a trust for each build? 1 trust is all you need, you can add or remove items that the Trust owns as you see fit.

You are absolutely right, and if I was going to be the only trustee I would have gone this route. But, I plan on adding some family to each trust going forward, and by creating a trust, obtaining my stamp with me as the only responsible person, then adding those people to the trust after, I skip the step of the process that would require them to get fingerprinted, jump through the hoops, etc. So basically the answer to your question is convenience.

You can still do that on a single trust. I just don't get it, but it's your world so rock on.

I'm definitely not an attorney, but my understanding is that you could, but you would just need to remove them from the trust every time you wanted to purchase something else, then add them back afterwards every time. In the time they were removed as trustees, they couldn't possess or have access to the items. Some of my family lives in different parts of Texas, and I sometimes like to leave my existing NFA items with them. Further, in the future, if I wanted to leave an SBR beside my bed for person protection, there could be a situation where I'm breaking the law if my wife isn't a trustee while I'm applying for another item. Again, not an attorney, but this is my understanding of the NFA laws as they exist today. Like I said earlier, the whole setup is designed to keep people from exercising their rights. Last thing is that one item per trust makes me feel a lot more comfortable. Kind of like having one piece of real estate per LLC. Not a requirement, but makes some people feel better.

Question regarding engraving:

My understanding is that you engrave the lower with your name and the town in which you built it (live). What if I move? Is there any kind of update requirement?

No need to update. The city listed is where the item is built, not where you live.

You are letting the internet get you into the fear realm.

What you are doing works, no issue with it, other than it just isn't necessary. Nobody is coming to knock on your door to verify if you have certain members on your trust at the exact moment you are sending in the application for a new NFA item, it just doesn't happen. You remove all members from the trust when you send your application in, then add them back after its sent. Easy peasy.

It's a silly act to have to do, for sure, because we have stupid firearm laws.

Might as well update my progress as well.

Got everything started back at the end of Feb, eform officaily "Submitted" Feb 27th (Same pending Research as RedPear, cause of the model name I chose).

Building a .30 Cal can. Will primarily be used on 5.56 AR, and 7mm-08 bolt gun, but may also throw it on a 30-30 once in a while.

Ordered the 7.8" Ti D tube, 2 end caps (One solid Ti, one with SD Tac QD thread in carbon steel), and 2 of the Shorty QD Muzzle Brakes.

Looking at Totality Industries for the guts, but I have some questions. They have 60 degree cones, radial cones (Bell Shaped), and short radial cones (bell shaped but flatter).

60 Degree Cone
Deep Radial Cone
Short Radial Cone

My thought is to have the first 2 baffles be SS 60 Degree Cones, then 3 Ti Deep Cones, then 2 Ti Flat cones, with the spacing between them getting progressively tighter (from what I've seen a lot of production cans use a similar layout, with baffles getting flatter and closer as you progress). Going to use Ti tube for the spacers.

Is this overthinking it?

Would there be a noticeable improvement over just using all flat cones, or all radial cones? Or should I just keep it simple.


Also, I have electro etched some carbon steel before, but I am not sure if this would work on the titanium. Anyone have experience with that? Could I get to the ATF required depth of .03"?

Last question, any other reliable options other than Burdett's to get a rifle barrel threaded around Brazos or Grimes county? I've dealt with Barry a lot, and got no problems with him, just always like to know other options.

Once it's all said and done I'll post a build recap with specs and a price total.

X-ray from several manufacturers. Designs vary, but in general you want a blast chamber before your first blast baffle, second chamber is large - but smaller than the initial blast chamber - then progressively smaller chambers beyond that. At least for centerfire rifles, pistols and .22's can be different.

And sometimes it's going to be a game of trying different configurations before you find something that works to your liking, but you have a good initial plan IMO. Go with it, get a few extra of each type of baffle so that you can play with configurations and see what you like best.

Gotcha. And I think I saw that same image a while back on arfcom, thats what had me thinking about that layout in the first place.

I'll make sure and have my preferred layout before I construct anything.

Last I heard eform approval was still around 3 weeks, so I'm hopeful I can hear something from BATFE by end of the month.

Day 12 of eForms submission....

My two applications have disappeared from the eForms website. "No saved forms found." Apparently this is a known bug...Good times.

BOOM--I've got a stamp for my 22 can!

Submission Date: 3/5/19
Fingerprint arrival: 3/8/19
Approval: 3/23/19 (God bless you for working on a Saturday, Mr. ATF Official)
18 days from submission (or 15 from arrival of fingerprints)

I'm happy this one got approved, but even more happy that I didn't screw anything up on it (since I did both of these the same way).

Now to drill baffles, cerakote it, and get it engraved, and start shooting it.



Here are the parts as they sit today: (Purchased from Diversified Machine - 1.125 x .995 - 6 inches - 1/2x28 thread)

Red Pear,

Did it show anywhere on the eforms site they they received your prints?
Or did ya just use certified mail to verify it?

Submitted mine end of Feb, still haven't heard back.

ETA: Nevermind. I called em. Apparently they haven't processed my fingerprints yet, even though my delivery receipt from USPS shows that they were delivered on March 4th.

Oh well, baffles haven't been shipped yet anyway.

To my knowledge, the eForms website doesn't show if fingerprints were received anywhere. I just logged in and double checked.

Also, stamp #2 arrived yesterday.

Sonuvab33ch.

Maybe they just don't like me.

Jennifer was very helpful on the phone at least, and recommended I call back tomorrow to check the status again.

You know what Jennifer? I think I will.

Form - 1 for SBR submitted 03-14-2019, received confirmation email on 04-01-2019 that my SBR had been approved and a digital stamp was attached.

Update:

Called back, fingerprints were never received in their system. USPS tracking showed that they were in fact delivered on March 4th, but there was no record of them. Was told to be patient.

Called back again. Dude on the phone was a bit of a *****, but recommended I submit an ask the experts ticket, cause he was only able to check the status, and not anything else apparently.

Did that last week. Called back this morning, and lo and behold my fingerprints magically appeared, and are being processed now. Lady said it could still be another 30 days or so, but I'm happy I don;t have to re-do the whole application.

All my internals arrived yesterday, so now I just need a stamp and to engrave my tube! (and drill out the internals which are being kept far separate from the tube for the time being.

What is your plan to drill and clip the baffles once you get your stamp?
