The handgun George Zimmerman used to take Trayvon Martin‘s life is now going to the highest bidder — and Zimmerman calls the weapon an “American Firearm Icon.”

The Kel-Tec PF-9 9mm is listed on GunBroker.com for what’s touted as a single-day auction on Thursday. Opening bid is set at $5,000.

Zimmerman’s not shy about the gun’s history either. His listing on the site includes this: “I am honored and humbled to announce the sale of an American Firearm Icon. The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin on 2/26/2012.”

Zimmerman was acquitted of murdering unarmed 17-year-old Trayvon.

He claims he will use money from the sale to oppose Hillary Clinton‘s campaign, and to fight what he calls Black Lives Matter fueled “violence against Law Enforcement officers.”

He says the gun is “a piece of American History.”
