Not an Attorney and maybe this isn't the current version but, read here:
https://www.congress.gov/bill/119th-...bill/2395/text
And then read Section 4 para f:
".........any person who acquires or possesses such rifle, shotgun, or other weapon in accordance with chapter 44 of title 18, United States Code,
shall be treated as meeting any such registration or licensing requirement with respect to such rifle, shotgun, or other weapon......"
So I'm not really sure where some of you are getting your comments.
Title 18 Chapter 44 are the usual "gun buying and possessing" Federal laws.
So for Colorado, under this we would buy/possess a MG, SBR etc like a "regular" firearm and under the CRS noted by Oneguy (
CRS 18-12-102), the buyer would automatically have "
valid permit and license for possession" under CO law.
Done and Done.
Now of course CO could react to this and amend or create new laws to address this but in the mean time............ salad days.
