Ex-Navy Seal Robert O'neill, 38, has told the Washington Post in another meeting he shot the lethal shot.
This negates the record of Matt Bissonnette, an alternate previous Seal included in the assault, in a 2012 book.
The al-Qaeda pioneer was executed in a 2011 Navy Seal assault on his compound in Abbottabad, Pakistan.
Mr O'neill, who resigned in 2012, had beforehand recounted his story namelessly to Esquire magazine.
He was booked to uncover his personality in a TV question later not long from now, however a site distributed Mr O'neill's name preemptively in challenge of his choice to open up to the world, the Post reports.
Mr O'neill said he and an alternate part of the group whose character stays mystery moved to the third carpet of the compound in Abbottabad, Pakistan and saw Bin Laden jab his head outside the avenue to one of the rooms.
The anonymous commando, at the point position of the arrangement, terminated at him however missed, concurring Mr O'neill.
A moment later, Mr O'neill went into the room and slaughtered the al-Qaeda pioneer with shots to the head, he says.
Be that as it may, in the book No Easy Day, Mr Bissonnette guaranteed it was the go-to person who killed Bin Laden.
On Thursday, Mr Bissonnette did not specifically question Mr O'neill's case, in a meeting with NBC News.
"Two distinctive individuals telling two separate stories for two separate reasons," Mr Bissonnette told the telecaster.
"Whatever he says, he says. I would prefer not to touch that."
Mr Bissonnette is planned to show up on the CBS news magazine program 60 Minutes in front of the distribution of his second book, No Hero, about his administration with the Seals.
In the interim, he is under scrutiny for possibly uncovering grouped data in his first book, about the Bin Laden strike.
The authority record of what happened is unrealistic to be uncovered by the US government for a long time.
Pentagon authorities have not affirmed or denied Mr O'neill's record, yet senior unique operations pioneers sent a letter a week ago to all Navy Seals urging them to follow their code of hush about operational subtle elements, including abstaining from assuming "open acknowledgment".
"We don't stand wilful or childish nonchalance for our center values as an exchange for open reputation and budgetary increase," they composed.
Container Laden was affirmed executed in the attack and his body was covered adrift.
Murkiness and lacking elbow room inside the compound have made some Navy Seals question whether it is conceivable to focus whose shots murdered the al-Qaeda pioneer.
