Suppressors Tax stamp question

When you bought the suppressor did you send a $200.00 check to the ATF with your paperwork? The ATF doesn't "charge" you, they just expect you to submit a check with your Form 4. If you didn't submit a check with your paperwork, it will get rejected and shredded (most likely).
 
I am pretty sure they are still doing paperwork. At least they are doing the in-processing part. I got charged for a few forms a couple of weeks ago.

Additionally, you have the option of using a credit card and just putting that info on the Form 4 now. Written checks are not the only option anymore But they definitely do that a long time before they ever get around to looking at your paperwork.
