Pinned/welded barrels no longer acceptable

[lorax3]

A fellow Calgunner linked me over to a blog which details a change that was made in the latest version of the NFA handbook which deletes the 'pinned/welded' method for extending lengths.

From the 2007 version of the handbook

NOTE: Any muzzle attachment such as a flash suppressor, compensator, muzzle break, etc., is not included in the barrel length measurement unless the attachment is permanently affixed to the barrel. Acceptable methods for permanently attaching a device to a rifle barrel are deep penetrating, full fusion, gas or electric steel seam welds of high temperature silver solder. Depending on the dimensions of a particular barrel it may also be possible to permanently affix a muzzle attachment by drilling a blind hole through the attachment and into the barrel wall. A steel pin that is flush with or below the outside diameter of the attachment is then inserted and the hole welded closed.

From the 2009 version

NOTE: Any muzzle attachment such as a compensator, choke device, muzzle break, etc., is not included in the barrel length measurement unless the attachment is permanently affixed to the barrel. Acceptable methods for permanently attaching a device to a shotgun barrel are deep penetrating, full fusion, gas or electric steel seam welds or high temperature silver solder.

Both from the rifle section, 2.1.3.

Does anyone have any information on this? Either the ATF just made thousands of illegal SBR's, or they just put SBR's into 'common use'.

Hope something positive becomes of this, little interest in paying a $200 tax stamp.

EDIT: Hmm yes, the 2009 version seems to talk about shotguns in the rifle section. Hopefully it is a BATFE error.

Look like an BATFE error...

I thought that's what the "E" was for.

seems like welding or silver solder is the acceptable method now.

NOTE: Any muzzle attachment such as a compensator, choke device, muzzle break, etc., is not included in the barrel length measurement unless the attachment is permanently affixed to the barrel. Acceptable methods for permanently attaching a device to a shotgun barrel are deep penetrating, full fusion, gas or electric steel seam welds or high temperature silver solder.
