One item I noticed while perusing the Remington site is that the new ML is a firearm, not a ML. I suppose the BATF didn't care for the setup, much like they put the skids on the original Savage.
I wonder if they'll ever catch up with the custom makers of similar designs?
The reason is you can return the original Savage ML, and apparently the new Remington, back to a cartridge rifle with the installation of the correct barrel. (Think T/C Encore) If a custom maker uses a cartridge rifle action to build their gun, then it is subject to BATF rules and requires a Form 4473 to transfer.
