Serial number on silencer

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Serial number on silencer

Post by Blk_n_gold » Fri Jun 19, 2020 6:30 am

For the serial number and model on a form 1 silencer can you use a steel stamping set?
The outer will be aluminum.

While you can, you need to be careful not to damage the tube wall. A close fitting mandrel should be used.

I thought about stamping the tube with punch stamps but the baffels fit so tight any deformation the baffels are likely to not slide out or back into the tube so smooth.
So much has changed since my last form 1

A dremel engraver will probably work just as well. Honestly though, why not just take it to be engraved somewhere?

You said in a previous thread you're making a .308WIN can & using 17-4 internals.

Aluminum of any sort should be 0% of that build. Any suitable material for your tube will not be marked with punch & hammer lettering. Recommend you find a shop local & have them do it. Even a trophy shop probably can. When it's time, take a sheet of paper and write EXACTLY what you want engraved. You will see tons of stories from guys with jacked up SBR markings since they just gave their lower and form-1 to an FFL with no further guidance and assumed.....If you don't want your zipcode or some other stupid stuff engraved, be very specific.

I was going to to use a dermal and a diamond tip bit.
But I just noticed there is an "embroidery and laser" shop in town so I might have to check that out.

This is what I do - stamp with a close fitting mandrel inside.

Do they argon shield when engraving titanium ?

Why ? So you can have shiny letters? Probably not.

Nothing to do with aesthetics.
That “non-shiney “ engraving on your titanium can is a brittle phase (alpha case) that substantially reduces fatigue strength. Suggest you take a few minutes to become better informed. The detrimental effects of laser engraving titanium has been discussed on this forum and is also available on the internet. That said, lots of folks are willing to roll the dice and laser engrave their titanium tube without argon shielding.
I have not been able to find a laser engraver who employs argon shielding. All my tubes are CNC or diamond point engraved.

I've used tarheestatefirearms for many of my engravings. While I don't pretend to know whether they use argon for shielding or not, I can honestly say all of the engravings they have done on Titanium has been just fine going back at least 6 years now.

But, what-ev's.

Total non issue.Theres a reason no one does it.

SHE doesnt use argon. No one does. She does all my tubes. Tarheel is 20 minutes down the road from my house. Her husband runs the class 3 shop and she does the engraving.

I guess Ecco Machine and I are the only two on this board who would disagree.
I am not parroting Ecco, I happen to have the background and experience with titanium to fully agree with his prior posts on this subject.

Yep. When you are the only one who disagrees and you cant bring up real world examples of where it was ACTUALLY an issue its hard to take what you believe seriously.Its not actually a problem. Belief systems are hard nuts to crack.

Been .223 shooting through laser engraved titanium cans for years. THOUSANDS of rounds. THOUSANDS. SHOW ME where I'm fucking up not some theoretical bullshit.

Bee, I'm jumping in late on this discussion but it seems that the depth and location of the ablative wield would determine if it would adversely affect the strength.
If it was over the blast chamber and to sufficient depth, I can see the crystalline structure becoming a problem. But 1/2 way down the tube, the pressure has substantially dropped. Also, laser ablation doesn't require much depth. How deep does the alpha case restructuring occur? How much does it weaken the hoop strength?

Very popular belief but also the wrong one. All ex Yugo cans had not only Al alloy tubes but also internals except blast chamber/mounting piece which was out carbon steel. I'm talking about AK, M-76 (7.92x57) and vz 61/M-84 (.32 auto) suppressors.
Nowadays, there's also PKM suppressor with Al tube but baffles are probably made out of steel.

It all depends on the duty-cycle of the host and the muzzle pressure.
AL tubes can't take a lot of abuse in those 2 areas.
Titanium is the king of tubes.
Everything else is a compromise.

I wouldnt call 17-4 stainless steel a compromise at all. Its a little heavier than Ti but who cares?
