good info.Were your cans backordered? The wait doesn't start until the forms have been certified and then submitted to the ATF. Order fulfillment and manufacturing is the current bottleneck. Supply of cans are so low that I have even seen a guy buy used suppressors. I, myself, have gotten 3 cans this year. One was approved in 4 days. The next was 31 days. And my 3rd can has been backordered since April.
Also, here's some Q&As from the ATF I thought pertinent to your situation
Q. Are NFA applications processed in a first in, first out basis?
No. While first in, first out is a guiding principle, NFA Division will focus its resources on processing those NFA applications that have received a proceed from FBI-NICS in response to the required background check. NFA applications were previously processed on a first in, first out basis, which resulted in delayed processing for NFA applications with a proceeded background check. For example, previously, a NFA application with a proceeded background check would not be processed until a NFA application with a delayed background check was resolved. Now, the NFA application with a proceeded background check gets priority for processing. NFA will continue to submit background checks to FBI-NICS in the order applications are received. NFA Division will then process NFA applications as it receives background check responses from FBI-NICS.
Q. If I have more than one application pending, will NFA Division process the applications at the same time?
Generally, yes, provided the applications are for an individual and the social security number was provided with the NFA application. NFA Division has implemented a bundling process which allows an examiner to review all pending applications of an individual. There is no need for an applicant to request bundling, this should be done automatically. Nor will NFA Division respond to requests to bundle applications beyond the bundling process that has been implemented.
Q. Why do trust applications take longer to process than individual applications?
Trust applications require the examiner to perform several additional steps of review than an individual application. For example, the examiner must read each trust document to ensure it is a legitimate trust. The examiner must also read each trust document to ensure every responsible person to the trust submitted the required responsible person questionnaire.
Q. I use a simple trust template with only a single responsible person, will my application be processed as quickly as an individual?
No. Even when a trust template is used and there is only a single responsible person, there are several additional steps the examiner must perform when reviewing an application to transfer a firearm to a trust. The review of a trust application will always take longer than the review for an individual application.
