Please keep in mind forms are not returned in the order they are sent. These dates should only be used as a guide, and in many cases, the dates on this page will not reflect your approval date or when your form will be returned to Capitol Armory. We will notify you as soon as we receive your approval from the ATF. Please read this page in its entirety before contacting Capitol Armory.

We are currently receiving approvals for forms submitted on the following dates:

There is a large misconception about 90-day approvals using the new ATF eForms system. While we are likely to have faster approval times using the new electronic system, at this time most approvals take longer than 90 days. Capitol Armory has submitted thousands of electronic Form 4s and only a handful have been approved in the 90-day time frame. The ATF will notify you via email when the item is approved. Shortly after the ATF email notification, Capitol Armory will send an email on how to have the items shipped or picked up at our TX location.



On 12/23/21, the ATF released a new and improved eForms website to submit electronic Form 4s. Many people in the industry expect the new eForms system to provide 90-day approvals, and we are likely to see that at some point in the future. Keep in mind, that each responsible party (co-trustee or individual) must undergo a background check at the FBI. If your background check is instantly approved (your background is squeaky clean) there is a chance the ATF will approve your Form 4 quickly. It is our understanding that if you do not receive a quick background check or have multiple responsible parties (more than one trustee on your trust), your Form 4 will take longer to approve even if it is electronically filed. 



Each responsible party (co-trustee or individual) must undergo a background check at the FBI. Your background check may be instantly approved, denied, or delayed. A delay at the FBI is not the same as a delay at your local gun store. A delay at the FBI requires a manual review performed by an FBI employee. We've seen delays take up to eight months to complete. Further, the system between the ATF and FBI is not updated frequently.  If your form is on the latter end of the time frame we're seeing for approvals, it is very likely that either you or a responsible party received a delay at the FBI. 



Capitol Armory will notify you via email the moment we receive your approved form. We suggest you whitelist our domain ( to ensure you receive our emails correctly. At any time, you may log into your account using the email address and password established when you ordered. Each order will show: Processing, eForm4 Certified/Submitted, Form 4 mailed, Form 4 approved, etc. If the status of your order is eForm4 Certified/Submitted or Form 4 mailed, it simply means we are waiting on the ATF to approve your paperwork. If the status of your order is Form 4 approved, you have been notified via email and you can pick up your items at our shop (TX residents only) or prepare the paperwork to have the suppressor shipped directly to your residence.  

If you filed electronically, the ATF will notify you of your approved Form 4 via email. Shortly after the ATF notification, you'll receive an email from Capitol Armory with the approvals and further instructions.



  • Forms are not considered "late" until the submission date (date we notified you it was mailed) falls a few weeks outside of the dates posted above. We monitor the progress of all ATF forms to ensure forms are not misplaced at the ATF/NFA branch. Recently, we've seen a small percentage of forms exceed the current average wait time. In every case, a responsible party of the transfer has had their background check at the FBI delayed. Details are not provided to Capitol Armory, but if you believe your background check may have been delayed, please contact the NFA Branch (304-616-4500) and ask to speak with the examiner for your form. You will need your serial number available when you call. The serial number can be found on your order confirmation email or in your account order details.
  • The NFA branch may take up to 30 days to mail your approved form to us. Capitol Armory will notify you as soon as we receive your approval.
  • If your Form 4 was submitted on or around the date range listed above and you have not been notified of approval, please be patient as each assigned examiner works at a different pace.
  • Orders with multiple Form 4s submitted to the ATF at the same time may be assigned to different examiners and approvals may return to us a few weeks apart. We will notify you via email when each form is approved and when your entire order is approved.
  • The dates above are the dates the forms were mailed/submitted to the ATF.
