My AMD65 with its original 12” barrel and welded extension...

'Question about your "welded" on barrel extension/brake; it's difficult to see in your image, but is the extension/brake that's attached to the muzzle of your AMD-65 build welded
only to the base of the front sight? If so, then the front sight along with the attached extension/brake can be removed by simply driving out the two pins that attach the sight to the barrel and unscrewing/removing the extension/brake from the muzzle, which is
not legal. Such devices must be
permanently attached.
For title 1 firearm legality such a barrel extension/muzzle device must be attached via
BATFE approved methods. See BATFE response below in regards to this issue, in particular welding, which is dated 1998, but the ruling has not changed:

Dear Mr. :
This refers to your letter of March 31, 1998, in which you ask
about permanently attaching a muzzle device to various firearms.
A muzzle device, such as a muzzle brake or barrel extension, which
is attached to a
barrel by means of welding or high temperature
silver solder having a melting point of at least 1,100 degrees
Fahrenheit, is considered to be part of the barrel for purposes of
measurement. A seam weld extending at least one-half the
circumference of the barrel or four equidistant tack welds around
the circumference of the barrel are adequate for this purpose.
A firearm having a muzzle brake, cap, or barrel extension
permanently attached by those same methods to cover the threads on
a barrel, would not be considered to have a threaded muzzle.
Please note, however, that any muzzle device or barrel extension
which functions as a flash suppressor or grenade launcher would
still constitute one of the qualifying features of a semiautomatic
assault weapon as that term is defined in 18 U.S.C. section
921(a)(30(B). Industrial adhesive products are not an acceptable
method for permanently attaching a muzzle device.
Mr.
We trust that the foregoing has been responsive to your inquiry.
If you have further questions concerning this matter, please
contact us.
Sincerely yours,
[signed]
Edward M. Owen, Jr.
