So would I end up paying for two transfers ( at 200 bucks each) to get it shipped to me after paperwork clears?
No, they are on a Form 3. You'd pay for the suppressor, they'd ship it to your local NFA dealer, you'd then mail in the Fork 4 paperwork with a $200 check. So for $500 you'd have a great direct thread 5.56 suppressor.
Plus probable NFA transfer at your FFL. I've seen some NFA transfers offered at $50.
BGF is up to $75 as of when they called me this morning.
