Serbu Firearms

In 2013, Serbu refused to sell their model BFG-50A semi-automatic .50 rifles to the New York City Police Department after the passage of the NY SAFE Act that classified their weapon as an assault weapon. Instances like this, in which a firearms manufacturer refuses to supply state entities with weapons that are forbidden to their private citizens, have become more common. Following their refusal to sell the rifles, Serbu then had T-shirts printed with an image of the classic Seinfeld character The Soup Nazi, played by actor Larry Thomas, and the words "No Serbu For You". Thomas, a gun control advocate, contacted Facebook and the T-shirt printers to have the shirts removed. Serbu has since removed the image of Thomas and replaced it with one of himself.[11][12][13]

On April 9 2021, firearms YouTuber Scott DeShields Jr., known for his channel Kentucky Ballistics, suffered critical injuries while recording a video shooting the model RN-50 rifle using old .50 BMG SLAP rounds. The gun exploded as DeShields fired the last round, sending shrapnel into his face and torso, lacerating his jugular vein and puncturing his right lung. He went through extensive emergency surgery at the Vanderbilt University Medical Center and was discharged after eight days, referring to the malfunction as a "freak accident" and blaming it on a faulty cartridge.[14][15][16] Mark Serbu released a video statement on the incident in his YouTube channel, to "assure people that the RN-50 is a safe gun", saying "It's a terrible thing. I’ve got 10,000 guns out there with my name on them and I don’t want anybody getting hurt with them".[17][18]
