The most armed man in America says he's sold more guns out of his Colorado Springs compound in the past three weeks than in the last eight months after two deadly mass shootings in Las Vegas and Texas.

Mel Bernstein, 71, became known as the most heavily armed man after he got thousands of high-powered weapons, bazookas and machine guns.

He claims to have over 4,000 weapons at his compound known as Dragonland, which includes a gun shop, six shooting ranges, military museum, paintball park, motorcross park and his home.

In the aftermath of two of the worst mass shootings in American history, Bernstein is having record sales.

'We've been selling more guns in the last three weeks than we have in the last eight months,' Bernstein said to ABC News.

Bernstein also said his gun shop sold out of bump stocks shortly after the Las Vegas massacre, which killed 58 people and injured over 500.

The gun owner is nicknamed 'Dragon Man' in reference to the name of his gun store and compound.
