I’ve done mine through Silencer Shop affiliated stores doing an individual eForm….once the initial fingerprints, passport photo, and forms are filled out it’s too easy to get a can….I’ve upgraded all of my 14-15 year old units.
As was stated earlier, the shipping takes the longest if your dealer doesn’t have what you want in stock…Form 3’s were in hours.
You ask about the new tech? My original YHM 7.62 stainless Phantom weighs 34oz with muzzle adapter….the TBAC Ultra 9 Gen 2 I upgraded to weighs 12oz!!!
The 3D printing does things that no wire edm, CNC, etc, can ever do….enjoy!
