The American Rifleman article The NRA has been accused of allowing a pro-gun group to sell merchandise that supports “the use of firearms for self-defense”.
The gun group, the National Rifle Association, says the products were produced by a company called Gun Nation and are not related to the group.
NRA spokesman Andrew Arulanandam told The American Conservatives: “We have been notified that a product from the Gun Nation line is no longer being sold.”
The NRA declined to comment further.
It has long been a vocal opponent of laws that protect gun owners, including those in the US, Australia and New Zealand.
It is also a strong supporter of the US gun industry, which is worth $4.5bn.
But in a statement to The American, NRA president Wayne LaPierre said the group was “very disappointed” by the claims, which it called “false”.
“Gun Nation is not connected to the NRA,” Mr LaPierre added.
“We are disappointed that these false claims were made and we will immediately review our position.”
The products included two pistols and an assault rifle, as well as a firearm holster and an ammunition pouch.
“The Gun Nation products are intended to be used for the individual and to not be used in conjunction with the AR-15 rifle,” Mr Aruladam said.
“Gun-Owning Americans should be able to use their own guns for self defence, not for mass murder.”
The claims came as a fresh batch of ads from the NRA appeared on TV, and appeared in print.
The adverts are designed to draw attention to the safety of firearms, and to “tell the NRA’s message”.
The ads will run in New York City, Chicago, Los Angeles, Houston and other cities.
The NRA’s position on the issue of gun control is complicated.
It says the assault weapon ban, which went into effect in the late 1970s, was “a misguided effort to make the American people safer” by giving law-abiding citizens more options.
The group says the gun control laws in the United States have failed, and are now contributing to the epidemic of gun violence in the country.
Mr Arulsantiam says that the NRA is not in favour of a ban on assault weapons and also has not been involved in the legislation that would allow states to make it legal for civilians to own them.
“They are just a lobbying group,” he said.
