Effective Immediately!!

Due to the recent changes in 2nd Amendment laws that are pending or currently enforced by states across the country, the J&T Family of Companies which includes J&T Distributing, DoubleStar Corp., Ace Limited, and the DoubleStar Training Academy has been forced to reassess our policies regarding government and law enforcement sales. Effective immediately, the J&T Family of Companies will be joining other manufacturers and distributors by ceasing sales of regulated items in states that have altered the rights of citizens to keep and bear arms. 

The JTFOC will no longer sell prohibited items to law enforcement agencies or any government agencies in states, counties, cities, and municipalities that have enacted restrictive gun control laws against their law abiding citizens.  We hope other companies will join us with their support.  We applaud those already involved with this effort to protect our 2nd Amendment rights.
