WASHINGTON (AP) -- Congress' latest crack at a new assault weapons ban would protect more than 2,200 specific firearms, including a semi-automatic rifle that is nearly identical to one of the guns used in the bloodiest shootout in FBI history.
One model of that firearm, the Ruger .223 caliber Mini-14, is on the proposed list to be banned, while a different model of the same gun is on a list of exempted firearms in legislation the Senate is considering. The gun that would be protected from the ban has fixed physical features and can't be folded to be more compact. Yet the two firearms are equally deadly.
"What a joke," said former FBI agent John Hanlon, who survived the 1986 shootout in Miami. He was shot in the head, hand, groin and hip with a Ruger Mini-14 that had a folding stock. Two FBI agents died and five others were wounded.
Hanlon recalled lying on the street as brass bullet casings showered on him. He thought the shooter had an automatic weapon.
Both models of the Ruger Mini-14 specified in the proposed bill can take detachable magazines that hold dozens of rounds of ammunition. "I can't imagine what the difference is," Hanlon said.
President Barack Obama has called for restoring a ban on military-style assault weapons and limiting the size of ammunition magazines.
A bill introduced last month by Sen. Dianne Feinstein, D-Calif. would ban 157 specific firearms designed for military and law enforcement use and exempt others made for hunting purposes. It also would ban ammunition magazines that hold more than 10 rounds.
Yet there are firearms that would be protected under Feinstein's proposal that can take large capacity magazines like the ones used in mass shootings that enable a gunman to fire dozens of rounds of ammunition without reloading.
Feinstein said in a written response to questions from The Associated Press that the list of more than 2,200 exempted firearms was designed to "make crystal clear" that the bill would not affect hunting and sporting weapons.
The December shooting at an elementary school in Newtown, Conn., that left 26 students and educators dead forced Washington to focus on curbing gun violence, a risky political move not tried in decades.
The gun industry, which is fighting any sort of ban, says gun ownership in the U.S. is the highest it's ever been, with more than 100 million firearms owners.
Obama and Vice President Joseph Biden have traveled around the country in an effort to gain support for new laws. Feinstein's proposal is the only sweeping piece of legislation designed to ban assault weapons currently being considered.
But some gun experts say the lists of banned and exempted firearms show a lack of understanding and expertise of guns.
"There's no logic to it," said Greg Danas, president of a Massachusetts-based expert witness business and firearms ballistic laboratory. "What kind of effect is it going to have?"
Feinstein's bill defines an assault weapon as a semi-automatic firearm with a detachable magazine that has one of several military characteristics that are specified in her legislation. Examples of those characteristics include a pistol grip, which makes a firearm easier to hold, and a forward grip, which makes the firearm easier to stabilize to improve accuracy. The definition is similar to the one in Congress' original ban on assault weapons, which went into effect in 1994 and was widely criticized for outlawing firearms based on cosmetic features.
Feinstein was behind the 1994 law which, at the time, protected more than 600 firearms. The current bill would exempt by name and model more than 2,200 firearms by name and model.
Feinstein said her staff had worked for more than a year to draft updates for the ban that expired in 2004, and it was apparent in the wake of recent mass shootings that now was the time to introduce a new bill. She said her staff consulted with law enforcement agencies and policy experts for months to create the expanded list.
Naming firearms that would remain legal under an assault weapons ban is a politically motivated gesture that was used to help pass the original ban in the early 1990s, people familiar with the process said.
Any firearm that does not fall within the law's definition of an assault weapon would not be banned. As a result, the list gives vulnerable politicians cover from constituents who do not want to give up their firearms.
For example, a politician can look at the list and assure a constituent that the government would not ban the firearm he or she loves to use for deer hunting. Under the 1994 law and the currently proposed one, the government would not have the authority to take away guns people already legally own. The ban would only apply to specific firearms manufactured and sold after the law is enacted.
