But the department reversed its decision Friday after a emotional backlash from students and community members who remembered the shooting that rocked the campus almost 31 years earlier.
On May 4, 1970, four Kent State students were killed and 13 were wounded by the Ohio State National Guard during a Vietnam War protest.
Police department officials said they wanted to buy the rifles -- the same used by the U.S. Army -- due to their low price and reliability.
Ron Kirksey, Kent State University media relations director, said community criticism led the school police department to back out of the deal to buy the M-16s.
"We are not going to take receipt of these weapons," Kirksey said.
He said the fact that the M-16 was a "military-type" weapon was "threatening the connection between our police and the community we protect."
Kent State Chief of Police John Peach said the M-16s represented a national trend to move away from lower-grade rifles and toward more reliable weapons.
Peach noted that other weapons used by the police -- including 9mm Smith & Wesson handguns -- were below standards.
He added that M-16s could penetrate glass with a clear hole left behind -- making it less likely for bullets to deflect and hit a bystander.
