The $212 million contract that Colt and FN won for M4A1 Carbines is not going through uncontested. Remington Arms Co. has named the two companies, along with the Federal Government in a sealed lawsuit, reports Guns.com:

Remington Arms named the federal government, FN America and Colt Defense in a lawsuit over a contract to provide weapons to the U.S. Army.

Attorneys with Remington filed the complaint in federal claims court on Nov. 24 and requested it and other court documents be sealed throughout the litigation, which the court agreed to.

In the motion to seal the documents, Remington said it wanted to protect proprietary information listed in proposals sent to the U.S. Army’s contracting office.

Although details are sealed, the motion lists a solicitation number to a October 2014 notice by the Army for a contract to produce 292,000 M4 carbines. In September, the Army awarded the contract, valued at $212 million, to both FN and Colt.

The court issued a protective order on Dec. 1 that details rules for the case proceedings and protects competition-sensitive information, to which all parties agreed compliance. Also, the court set deadlines for hearings. Defendants have until Jan. 25 to submit answers to the complaint, and oral arguments are scheduled for Feb. 26.
