Wild video captures the moment the victim of a savage Bronx beatdown turned the tables on his attackers Monday afternoon – firing off gunshots that left one of the brutes clinging to life.

The brief clip obtained by The Post shows two young men cornering their victim against a wall during the violence that broke out just before 1 p.m. on Commonwealth Avenue near Westchester Avenue in Soundview.

At one point, one of the assailants kicked the cowering victim in the face while filming the brutal ordeal on his cell phone.

After taking the blows, the violent pair’s target then got up off the ground, as one of the attackers – seen wearing a black T-shirt and orange shorts – held him from behind, the footage shows.

The victim then fired a gun over his shoulder, striking the shorts-wearing perp, 27, in the torso and leaving him gravely wounded as he lay sprawled-out on the sidewalk.

The cameraman, seen wearing red sweatpants and a white T-shirt, ran off as the victim-turned-gunman sent more rounds flying in his direction, the clip shows.

The shooter, seen wearing black pants and a black sweater over a white shirt, calmly walked past the felled attacker and glanced at him on the ground before the clip cut off.

Cops say the injured man was taken to Jacobi Medical Center, where he is listed in critical condition.

No arrests have been made and the investigation is ongoing, police said.
