A black man claims Walmart employees refused to sell him a gun even though he's licensed because of his race.

Video of the incident shows the man, who remains unidentified, arguing with the employees and asking them to explain why they won't sell him the weapon.

'Tell [the manager] what you just told me,' the man tells the Walmart employee. 'You felt uncomfortable to sell me a firearm, why?'

The employee replies: 'It's uncomfortable because it's a red flag for us that you seem a little bit antsy to purchase it.'

'I got a gun licence, man! What are you talking about?' the customer asks.

The Walmart employee then claims the customer did not have a license when he first applied to purchase the gun.

The customer replies that he did have the license, which he's had for a long time and recently used to buy two guns at Academy.

It's unclear when exactly the customer first tried to buy the weapon at Walmart.

'This dude shouldn't be working back here, man,' the customer tells the manager.

The Walmart employee, the customer claims, knew he had a licence and still looked him up.

'I've been waiting for months to purchase my firearm and I still can't purchase it because he feels uncomfortable,' he tells the manager.

The manager then explains the man's request to buy the gun came back as 'delayed' so it's red flagged.

'If ya'll don't want to see black people buy a firearm just say that,' the customer says

But the customer insists that he can't be red-flagged in the system because other stores let him buy guns.

'If ya'll don't want to see black people buy a firearm just say that,' he tells the manager.

The customer claims he called the FBI to see if he had been red-flagged and they replied it was up to Walmart to sell him the gun.

The location of the Walmart remains unclear.
