Email [email protected]. It might help. My 1 and 4 submitted at the same time were done in 36 and 33 days.I'm in the same boat. I have an eForm 4 for a suppressor and an eForm 1 for an SBR. The Form 4 is now 2 months in and the SBR is 1 month in (despite having 2 other suppressors and one other SBR already approved in the system).
