Modify a Suppressor?

[CP]

I'd like to suppress my 9mm carbine but, you know, tax stamp, big $$, wait and wait ... and wait. 

Or I could bore out my .30 caliber can.  Stupid idea?  Has anyone done this?

My can's bore is .355", I could run a size Y bit through it (on a lathe, not a cheap cordless drill) and bring it up to .404" should do the trick.

Very very bad idea, especially if you talk about it online where the ATF guys can see you. If your suppressor is registered as a 30 cal, it is illegal for you to modify it to a larger caliber. Not worth the risk of prosecution, don't do it.

Thanks.  Felony avoided.

I found this little tidbit after an exhaustive search:

"If alterations to a silencer would increase the overall length or change the diameter or caliber of a silencer, this is the making of a new silencer, as opposed to a repair."

i have a question. Just curious....Does a permit go with each suppressor, or does a permit cover all suppressors.

Each suppressor gets its own tax stamp/permit.

I'm not sure what you mean by permit but if you are referring to the Form 4 Tax stamp, then yes, each and every item requires the $200 stamp.

Thats probably what I am referring to.  I had a coworker applying for one for a suppressor and one for his AR.  SOme sort of license.  Seemed like a painful process

The ATF paperwork and tax is basically for permission to legally purchase and own one suppressor. It's a one-time fee (just like the purchase price) that is specific to that particular item. You never have to pay it again for that suppressor, but if you want to buy another, you'll have to go through the paperwork and tax again for that one.

THANK YOU

It's really not all that painful or difficult of a process, are there a couple little things, like passport photos and fingerprint cards, that're kind of a PITA but it's really not all that big of a deal and the whole process is a lot less difficult than you'd think.  The worst part about the whole deal is the dreaded "wait" but from what I'm hearing that's down to around 6 months or maybe even a little less now.

Silencerco has a can called the hybrid it will fit a 9 mm through 45acp and 5.56 through 4570. I guess it's okay because you're not actually changing the can you're just able to change the attachment piece.

It is acceptable (legally speaking) to shoot a smaller caliber through your suppressor. What's not acceptable is modifying it to be something different than what is listed on the approved form.
