Marlin Firearms Co., which is part of Freedom Group, is closing its New Haven, CT plant. All 265 employees will lose their jobs.

Remington Arms Co. Inc., which operates Marlin, said the Connecticut plant will close by June 2011 and employees would be offered severance and help finding jobs. Production is being relocated to an undetermined site.

A statement from Freedom Group said, “Although long term prospects of the business look positive, economic factors beyond Freedom Group’s control related to increasing costs and pricing pressures within the firearms industry are impacting the entire Freedom Group of companies.”

Remington Arms bought Marlin for nearly $42 million in 2007.

Marlin’s website states John Marlin opened the company in 1870 in New Haven after having worked at the Colt plant in Hartford during the Civil War. The company says its lever action 22 repeater was a favorite gun of Annie Oakley.
