MK19 MOD-4 Grenade Machine Gun (GMG), MK19 MOD-4 Spare Parts Kit, and MK 19 MOD-4 Additional First Article Test (AFAT)

This contract modification, issued by the Department of Defense through the Army Contracting Command-New Jersey, increases the ceiling of an existing IDIQ contract with US Ordnance for the MK19 Grenade Machine Gun. Executed under the authority of 10 U.S.C. Section 3204(a)(1) and FAR 6.302-1, this is a sole source procurement based on the determination that US Ordnance is the only responsible source capable of satisfying the agency requirements without causing unacceptable delays or safety risks. The scope of the modification includes the production of MK19 MOD-4 Grenade Machine Guns, spare part kits, barrel assemblies, and additional First Article Testing. The work is associated with NAICS code 332994 and is performed in McCarran, Nevada. This action ensures the continued availability and support of critical weaponry through the procurement of both finished systems and essential maintenance components.
