Posting the above article because some in the media are misstating the BATF raid on Polymer80's manufacturing facility as a turn in policy to be against 80% lowers, etc. As the above article explains, the raid was specifically an investigation of the "Buy Build Shoot Kit" for a handgun, and not 80% AR15 lowers. The kit as sold includes all components necessary to build a complete handgun with the 80% handgun frame.
The investigation focused primarily on the company’s “Buy Build Shoot Kit,” which includes an 80% finished handgun frame and the components necessary to assemble that frame into a complete Polymer80 handgun, according to WSJ, which cited an ATF warrant. The agency determined that the set sold together meets the definition of a firearm and thereby would require a background check for purchasing, WSJ reported.
...The agency previously approved Polymer80’s frames for sale, but the kits themselves were not submitted for ATF approval, WSJ reported.
