Legal question on baffle caliber
I have two questions, When I fill out a form 1 and I say the suppressor will be 22 cal can I make my baffles larger? Do they all have to be the same caliber?
Second question is is if I have a second form 1 suppressor and it uses the same baffles could I interchange said baffles between the two Suppressors?

Re: Legal question on baffle caliber
the baffles don't really have a caliber. There's no standard for what size the hole in a baffle should be. They're all oversized but not to the same degree. Likewise, some silencers have baffles with hole diameters varying slightly throughout the can. I'm confident I could shoot 6.8mm Remington through some 6.5mm silencers or 243 through some particular 223 silencer. If the form 1 says 22 but 50 caliber bullets for through, it might raise eyebrows but I don't think you'd be breaking any rules. If the form 1 says 50 cal but 30 cal bullets don't even fit through, you're in trouble.
If you want to make a 22 silencer with baffles capable of passing 30 cal bullets, just register it for 30 cal and put it on a 22 caliber firearm.
I wouldn't mix baffles between silencers. I'm not sure of any law specifically forbidding it, but the definitions of silencers and silencer parts are so vague that you could probably be charged with something, depending on a judge's interpretation of the laws and rules.

Just so long as it is able to shoot the caliber that's filed on the form then it's good, correct?
Re: Legal question on baffle caliber
Personally I would make the baffles "appropriately" sized per the approved Form1. if you want to make a change, you can always send the ATF a letter notifying them of a permanent change to your design.

Re: Legal question on baffle caliber
If you design a suppressor to be able to handle 50cal, but register and mark it as 22lr, I could see ATF trying to make a case of it. Not saying they'd have a reason to come looking for you, but we're BS'n about it so this is my opinion. They could claim your intent was to suppress 50cal, as the 2 designs are on opposite ends of the design spectrum, and therefore made an illegal caliber change. You'd have to prove, in court, that you're too stupid to look at 22lr designs (from the past 100yrs ) and replicate one of them. The ATF would show modern, large-bore, silencer designs and compare them to yours. Not too hard to see where I'm going . Again, no reason to believe they'd be coming to your door, in the first place.
Haven't seen a case to prove it, but swapping baffles could be construed as "replacement parts" which would violate NFA rules.

Re: Legal question on baffle caliber
I'm confident that you can't have extra baffles.
In other words, baffles for a 22, and baffles for a 30 cal.
I understand what you said about having a can for each, but mix-n-matching, I wouldn't feel comfortable doing.
Some silencer designs do have different endcaps available for them. The 30 caliber cans with a 22 caliber endcap for instance. Though I don't know how effective they are.
I don't pretend to know the legality of that in a form 1, but I will assume that if it's good for one, it's good for all since they're all registered silencers. But that's an area where I have seen nothing definite about them either way.

I own multiple Spectres and clean all the baffles in the same tub then put them back into any old random tube except for the blast baffle which is marked and each tube gets one at random.
All baffles are the same caliber and all baffles match the caliber designation for which the suppressors were made.
If I had two identical tubes, one registered for 22lr and the other registered for 9mm with baffles sized appropriately for each caliber I would not mix the baffles. Besides being a dumb idea it's illegal, most laws are designed to protect dumb people anyway.

Re: Legal question on baffle caliber
yes but its still a 22 as it can fire 22. its not like im registering it as a 30 cal can and then making the baffles 22 and it not being able to fire 30 like its meant to.T-Rex wrote:If you design a suppressor to be able to handle 50cal, but register and mark it as 22lr, I could see ATF trying to make a case of it.

over boring is a thing and my ruger mark iv that i had threaded doesnt seem to have the best bore concentricity.
i also plan on threading my k31 with the hand threading kit and that definitely wont have good concentricity.

Re: Legal question on baffle caliber
I don't see anywhere where it says that if I make a 22 cal suppressor I must have it be bored to 22. Like I said I have a mark iv with a threaded barrel that doesn't have the best bore concentricity and in the future I plan on buying a 220 swift rifle and again I bet the bore concentricity won't be that good.doubloon wrote:You completely skipped over or ignored the part of my post that said "baffles sized appropriately for each caliber".Hannibalbarca wrote:...

So with this being said, again both are registered for 22, I see no reason why I wouldn't be able to intermix baffles between the Suppressors. There are no extra baffles here, just the ones in the 2 Suppressors.
Re: Legal question on baffle caliber
Suppressors loose efficiency as the bore increases. One designed for a .22 with appropriate bore would be quieter than one with a .50 cal bore.
See ADCO if you need your threads fix or just buy a new barrel and call it good.

Re: Legal question on baffle caliber
Well, there is no requirement that your suppressor even has to have baffles...I think you will find that a can with holes for a significantly over-bore projectile is going to suck as a .22 LR suppressor, but I understand the urge. Adding a final and/or an intermediate wipe(s) to a .30 (or larger) can will at least make it a little more effective as an expansion chamber, and if they are pre-punched you could potentially shoot any projectile diameter up to the major diameter of the baffles. ( At the cost of accuracy, shorter service life, and higher pressures) I would not try to shoot through intermediate wipes: too much danger of baffle strikes.
Re: Legal question on baffle caliber
The form is requesting you to specify a caliber or gauge for the suppressor not the size bullet you plan to shoot through the suppressor.Hannibalbarca wrote:...

it's a request for you to specify the caliber, the gauge, the diameter of the hole(s) through which the bullet will pass after leaving the muzzle.
Is it really that hard understand?
Besides the 'tacticool' factor of being able to say "I built this suppressor myself with 1/2" holes in the baffles for a less than 1/4" bullet because I wasn't sure I could drill a hole straight." what's the advantage of not just marking it 50 caliber?

Re: Legal question on baffle caliber
What about this doubloon:
Is it legal to shoot 9mm through a 300 blk silencer, or 243 through a 223 silencer? The 50 cal hole and 22 bullet was just an exaggeration to show that the law is vague and unclear about what defines a silencer's caliber. My 300blk silencer has enough clearance for 8mm, 32, or 9. Can I use it on those guns or would that constitute a change of caliber? Is the silencer I made even really legal?
Exaggerating aside, asking what size the baffle hole can be/ has you be is not a stupid inquiry.

The caliber designation on the Form 1 is the caliber of the suppressor, plain an simple.
If you want to make a 45 caliber suppressor and shoot 22 through it no problem. If you want to make a 9mm suppressor and shoot 50 cal through it, still no problem.
You want to complete a form saying you are making a 22 caliber suppressor and you actually make a 50 caliber suppressor, that could be your problem.
I am not saying anyone ever has or ever will go to jail for lying on a Form 1 or a Form 4, given the state of the records in the NFA registry I'm almost certain nobody will every find out and even if they did they probably couldn't rub two subpoenas together to start a trial.

I have a Form 1 that was approved for a 10" 45 caliber can that I have never even started working on yet. What I was wondering was if I could write a letter asking for either the length or caliber to be changed on the form?

Re: Legal question on baffle caliber
You don't have to ask permission to change the length. This can be done by simply sending in a letter with the stated change. If you haven't built it yet, they may allow you to amend the caliber. Can't hurt to ask. Email Gary at [email protected].Elkins45 wrote:
