A now-viral photo showing a long line of Connecticut residents waiting to register their guns and ammo is circulating across the Internet — and it’s sending chills down the backs of some gun owners.

Connecticut gun owners are rushing to register certain firearms and ammunition that will be considered illegal contraband in the new year.

Under a wide-ranging gun control law passed after the Sandy Hook Elementary School shooting in Newtown, they have until Tuesday to submit the paperwork with the Department of Emergency Services and Public Protection.

“Holy crap. Looks like Weimar Germany,” Twitter user @votermom said of the photo.

“Another disgusting picture from Connecticut . . .men waiting in line to register guns with the government,” user @chipwoods commented.

“First, they came for the guns,” @PaulRReyes added.

“Life is too short to live in a state that does this to its residents,” Twitter user @lancemfisher declared.

And there are plenty more comments where that came from.

State police say they’ve had people lining up early in the morning to turn in applications to keep high-capacity magazines that hold more than 10 rounds and guns considered assault weapons under the new law.

While the Connecticut Citizens Defense League believes the law is unconstitutional, it has been reminding gun owners of the deadline to make sure they don’t become felons on Jan. 1.
