a shooter unloaded his weapon on a man who was trying to defend his girlfriend from two creeps inside a Queens convenience store this week.

The clip, obtained by The Post Thursday, shows the 34-year-old victim entering the One World Convenience store in Richmond Hill and apparently exchanging words with two men standing near the door.

One of the men shoved the victim, who then squared off to fight, the clip shows.

That’s when the man standing behind the shover raised a black gun.

He is shown firing off a single shot that appeared to miss the victim – but shattered the glass door of the store.

Then the gunman kept firing, pelting the victim with bullets until he fell face down onto the ground..

The two menaces stepped over the victim – the gunman still holding his weapon – as they fled from the store, the footage shows.

The gravely wounded man is shown trying to crawl on the ground before the clip cuts out.

A later portion of the footage viewed by The Post but not released, shows the victim’s girlfriend running back in the store and screaming as she hugged her loved one on the ground.

The horrifying scene frightened the worker behind the counter, who “dropped to the floor,” the manager said.
