The gun company has been criticized for making guns that resemble a fake toy guns.
Culper Precision said the weapon, dubbed Block19, was designed to give the user pleasure while in shooting games.
But a Danish doll maker wrote to the company to stop making the weapon, which resembles a 'Lego bricks' toy.
Proponents of her case have been working to make the actual transcript of this statement available online.
Shannon Watts, of the city's gun safety group, said his agency was involved with Lego in the manufacture of Block19 rifles last week.
And the Danish company has sent a letter to Culper Precision asking for the weapons to be banned.
Ms. Watts criticized the gun company in Utah, saying it was dangerous for children and could lead them to use weapons even if the gun did not look like a toy.
Culper Precision issued a statement deciding to launch this Block19 weapon and show how the gun can be used by everyone and enjoy shooting.
And add that the weapon can only be bought by those who are legally allowed to own a gun.
Culper Precision president Brandon Scott told the Washington Post that he would hold talks with a lawyer to determine if he would accept the application he received from Lego.
The weapon appears to have been removed from the gun manufacturer's website.
