MCNALLY INDUSTRIES, LLC

McNally Industries, LLC specializes in the precision manufacturing and engineering of mission-critical defense components, with deep expertise in small arms, ordnance systems, and specialized mechanical assemblies. The company designs and produces high-reliability components such as machine gun housings, ammunition hoists, and track assemblies, alongside fluid metering and counting devices used in military and aerospace environments. Their technical capabilities extend to precision metal fabrication, mechanical integration, and maintenance kit development for air and ordnance systems, demonstrating proficiency in meeting stringent military specifications for durability, safety, and operational performance under extreme conditions. The firm’s ability to deliver complex, low-volume, high-precision parts on tight schedules distinguishes it as a trusted supplier for specialized defense applications. The company maintains a consistent and long-standing relationship with the Department of Defense, supplying components across multiple branches, including naval systems through direct engagement with NAVSEA. Their work supports land, sea, and air platforms, with a focus on ordnance handling, weapon subsystems, and auxiliary equipment critical to combat readiness. While NAVSEA is a key partner, the breadth of engagements across DoD components indicates a broad-based, mission-aligned supplier relationship rooted in technical reliability and responsive production. McNally Industries operates primarily within the small arms and ordnance manufacturing (NAICS 332994) and totaling fluid metering (NAICS 334514) sectors, serving niche markets requiring exacting tolerances and defense-grade materials. Their vertical specialization lies in mechanical subsystems for military platforms, positioning them as a tier-two supplier with deep domain knowledge in weapon systems integration and precision fluid control. As a small, Wisconsin-based manufacturer with no federal certifications listed, McNally Industries competes on technical execution, quality control, and responsiveness rather than formal socioeconomic designations. Their geographic footprint is centered in Grantsburg, Wisconsin, with a focused presence in the defense industrial base.
