if your FFL didn't have it in stock. Then yes that's to FFL from mfg / vendor. It's also the Form 3. IF you got a F 4 approved in 4 months i'm doing another factory SBR, maybe.
You misunderstand. The suppressor is already on a form 3 with my dealer waiting to be picked up by me. The question mark signifies the unknown time that it will take for the actual form 4 hard copy to be received by my dealer. But yes, my form 4 only took 4 months.
