The inexpensive 5.56 M855 ammo, commonly called lightgreen tips, have been exempt for years, as have higher-caliber ammunition that also easily pierces the type of soft armor worn by police, because it’s mostly used by target shooters, not criminals. The agency proposes to reclassify it as armor-piercing and not exempt.

But now BATFE says that since the bullets can be used in semi-automatic handguns they pose a threat to police and must be banned from production, sale and use. But, as Goodlatte noted, the agency offered no proof. Federal agencies will still be allowed to buy the ammo.

“This round is amongst the most commonly used in the most popular rifle design in America, the AR-15. Millions upon millions of M855 rounds have been sold and used in the U.S., yet ATF has not even alleged — much less offered evidence — that even one such round has ever been fired from a handgun at a police officer,” said Goodlatte’s letter.
