I've bought a suppressor through gunbroker that made it to my silencershop dealer. However silencershop isn't starting the form 4 as BP firearms is listed as the manufacturer for the suppressor instead of dead air. At this point it's been a month of my dealer and I both reaching out to silencershop and getting the run around about it being "with compliance" or whatever else. Right now as it stands i have a completed form 3 just waiting on the F4 to me to be started. Where do I go from here?
