A new report from the gun blog website AmmoLand Shooting Sports News claims that Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) agents have shown up at the homes of "multiple people" to confiscate previously legal forced reset triggers for AR-15 style rifles that were recently classified as "machine guns."

"It is possible the ATF received the customers' information from credit card processors or shipping companies," AmmoLand said, adding the federal agency had received customer information from Authorize.net and Stamps.com to track people who've bought 80% lowers from gun parts kits manufacturer Polymer80. 

A person named "Paul Britton Finch" is allegedly one of those gun owners who got a knock on the door from ATF agents. 

"Just a heads up, I got a visit today from the AFT for a trigger I bought from gunbroker and one from Rare Breed directly...hide your dogs, ladies and gentlemen. They're comin' a knocking," Finch said in a post in what appears to be a gun forum. 

He continued: "I don't want to say much more on here because they [ATF] do infact watch this group and who posts what information. so take what you will of it. They're out there with all the information you used to buy them with and enough to prosecute you if they want to push it. Yeah it sucks, but that's the reality of it right now."
