Flamethrowers, including those from Elon Musk's Boring Company, are causing concern among New York lawmakers. 

The New York State Senate passed a bill this month banning the possession of flamethrowers for recreational use. Having one would be a Class E felony, which could lead to up to four years in prison, according to a CNBC report on Friday. 

"Elon Musk's Boring Company released a new flamethrower which sold out of all 20,000 within days, without any concern to the training of the purchasers or their reasons for buying," lawmakers said in a release. "Allowing the general public to access this type of machine is extremely problematic."

Last year, Musk tweeted that the company changed the name of the product to "Not a Flamethrower" because of "recent regulatory/customs rules enacted to inhibit transport of anything called a Flamethrower."

The bill, sponsored by Democratic Sens. John Brooks and David Carlucci, passed the Senate 48-13 on June 11. It hasn't yet been voted on in the Assembly. 

The New York State Senate and The Boring Company didn't immediately respond to a request for comment. 

This isn't the first time lawmakers have tried to ban the Boring Company's flamethrowers. Assemblyman Miguel Santiago, a Democrat from California, said last year he planned to introduce state legislation blocking sales of the flamethrowers to the public.
