Joe Biden's Bureau of Alcohol, Tobacco, Firearms and Explosives has been nailed with a lawsuit.

It's from the type of guys you probably don't want to get on the bad side of:

The National Rifle Association.

The lawsuit is concerning a rule that regulates stabilizing braces for pistols.

The lawsuit, filed on July 3, exposes "the failings of the new rule – which subjects law-abiding gun owners to penalties, fines, and potential prison sentences for the use of an otherwise legal plastic apparatus on some firearms."

NRA Executive Vice President & CEO Wayne LaPierre said that "the NRA has ramped up its offense on this arbitrary and unconstitutional rule."

"We are confident in our ability to confront the ATF and the Department of Justice – and preserve freedom for NRA members."

Pistol braces are defined by Fox News as "accessories that can be attached to the rear of a gun to make it easier to aim and fire with one hand. The accessories are often used by disabled veterans."

Biden's administration has classified such pistols as "short-barreled rifles," which require a federal license to own.

Obviously, a disabled veteran isn't using a short-barreled rifle, he's using a pistol made to accommodate the sacrifice he made for this country.

It's moves like this that practically spit in the face of the people who built this country that has made America hate Joe Biden and his family.

Joe is apparently willing to sit down and look through the nuances of Hunter's Biden cases so that he can come up with a defense for why his son shouldn't be in jail.

When it comes time to apply the benefit of the doubt to America's disabled veterans however, Joe Biden does not want to give them the same type of grace that he gives his deadbeat son Hunter Biden.

The NRA is quite sure that the new rule categorizing these handguns as "short-barreled rifles" is unconstitutional.

"The NRA is pursuing every possible avenue in defense of its law-abiding members and their constitutional freedoms," said William A. Brewer III, counsel to the NRA. "Our members should be free of the threat of enforcement of this presumptively unlawful rule. We are confident that we will prevail in obtaining the same relief for them that has already been granted to members of other gun rights groups."
