The Second Amendment Foundation will launch a nationwide TV and radio campaign Monday aimed at exposing legal holes in President Obamas executive actions to ban ammunition commonly used in AR-15 sport utility rifles.

We bought $700,000 of time on Fox News and Glenn Becks Blaze network, Alan Gottlieb, the groups founder and executive vice president, told The Washington Times in a Sunday telephone interview. Its aimed at getting our legal argument out to the public, and at getting support for a possible lawsuit.

The foundations one-minute commercial heralds 1 million Americans to call a toll-free number to voice their concerns, make a contribution and target Mr. Obama for exercising another executive power grab.

The ad claims, The Obama administration was unable to impose gun restrictions and confiscation through the legislative process, so now its trying to ban commonly used ammunition through regulation. If we allow Obama to ban ammunition through executive fiat now, it will lead to the loss of our Second Amendment rights by the time Obama leaves office.

Press secretary Josh Earnest said last week that Mr. Obama supports the ban because he predicts that the AR-15s .223 caliber M855 ammunition will be used to pierce law enforcement officer armor, although there are no such reported cases to date.

The Second Amendment Foundations media campaign is being launched only days after it sent a scathing legal threat to B. Todd Jones, director of the Bureau of Alcohol, Tobacco, Firearms and Explosives. In addition, 239 congressional lawmakers, including seven Democrats, dispatched a letter voicing their own concerns to the federal agency.

The proposed regulations, which ban the production and sale of the steel-tipped ammunition was a response to an ATF report that claims new handguns are capable of firing the ammunition. But the new AR-15 handguns are nearly 2 feet long, and weigh about 6 pounds, making them almost impossible to conceal like a traditional handgun.

The administrations logic does not satisfy the requirements under federal law to classify the ammunition as armor piercing, the foundation argues.
