As the school shooting in Parkland, Fla., stokes the national debate over firearms, it may be easy to overlook another major development in the gun world this week.

One of the nation’s oldest and largest gun makers, Remington, said it was nearing a bankruptcy filing.

Hit with slumping sales and unable to sell itself, Remington has negotiated a deal with its lenders to cut its debt and keep operating.

Other gun makers are also struggling. Colt completed its trip through bankruptcy last year, while sales and profits at Smith & Wesson’s parent company have plummeted and its stock price is sagging. All three companies make a version of the AR-15-style semiautomatic rifle, which was used by the killer in Parkland on Wednesday and is the weapon of choice for mass shootings.
