"Was it a real gun or was it a fake gun?" Deputy District Attorney Paul Przelomiec said on Thursday. "Nothing else is in dispute."
Both sides gave their answers during closings at the Los Angeles trial, where the hip-hop star is accused of firing at a former friend on a Hollywood street in 2021.
Przelomiec argued Rocky was undeniably guilty of two felony counts of assault with a semiautomatic firearm.
The defence says the gun was a prop that fires only blanks Rocky took for security months earlier from the set of his music video for "DMB", which featured Rihanna.
Rocky's lawyer Joe Tacopina said the accuser and key prosecution witness was "an angry pathological liar" who "committed perjury again and again and again and again".
Rocky, the Grammy-nominated music star, fashion mogul and actor whose legal name is Rakim Athelaston Mayers, is the longtime partner of singing superstar Rihanna, who has attended the trial sporadically.
For the first time, she brought their two sons - two-year-old RZA Athelston Mayers and one-year-old Riot Rose Mayers - entering the courtroom quietly but dramatically a few minutes into closings.
The boys, wearing suits, could be heard cooing as the prosecutor talked. Rihanna held one on her lap and tried to keep him quiet with a toy.
During a break, Rocky walked down the hall, past jurors, holding the younger boy. Rihanna returned to court without them after lunch.
The defence will complete its closing argument on Friday. After a rebuttal from prosecutors, jurors will begin deliberations.
Rocky could get up to 24 years in prison if convicted.
The jurors are not supposed to know the possible sentence. But during testimony, Rocky's tour manager, Lou Levin, said, "I read that he was facing 24 years", after a prosecutor hounded him about whether he wanted to see his friend and sometime boss convicted.
In his closing, Przelomiec said it was intentional.
Rocky and the man he's accused of shooting, who goes by A$AP Relli, became friends in high school in New York. Both were members of a crew of creative types called the A$AP Mob.
Their friendship continued after Rocky gained global fame with No. 1 albums in 2012 and 2013, but by November 6, 2021, their bond had become a beef.
They met up outside a Hollywood hotel and scuffled. In a second confrontation moments later, Rocky fired the shots. Relli said his knuckles were grazed by one of them.
Tacopina called the injury "knuckle scrapes."
"There's no bullet in the world that could've done that," Tacopina said, showing jurors a picture of Relli's hand.
