Im in the process of saving up for a suppressor for my .308. Dont have the money for the stamp and suppressor all at once but im wondering if i can purchase the stamp before i purchase the suppressor. It would be nice to the stamp ready to go when it comes time to make the purchase so i dont have to wait forever to get the stamp. Is this possible? Also, if for whatever reason your aplication doesnt go through for the stamp, do you get your 200 dollars back?
