A US gun company is facing a backlash for producing a pistol that looks like a children’s toy made of Lego. Culper Precision said its customised Glock weapon, named Block19, was developed to “highlight the pure enjoyment of the shooting sports”. But Danish toymaker Lego has written to the company demanding that it stop producing the weapon, which is covered in what looks like Lego bricks. Gun control campaigners described the pistol as irresponsible and dangerous. Shannon Watts, of the Everytown for Gun Safety campaign group, said her organisation had contacted Lego about the customised Block19 last week, and that the Danish company had then sent a “cease and desist” letter to Culper Precision.
