BARTLEIN BARRELS, INC.

Bartlein Barrels, Inc. specializes in the precision manufacturing of small arms barrels and ordnance components, leveraging advanced metalworking techniques to produce mission-critical firearm systems for defense applications. Their technical expertise includes cold hammer forging, precision bore machining, and heat treatment processes that ensure dimensional accuracy, material integrity, and ballistic performance under extreme operational conditions. The company’s specialization in small arms barrel manufacturing positions it as a niche supplier within the ordnance supply chain, focused on delivering reliable, high-tolerance components that meet stringent military specifications for durability and consistency. Their capability is rooted in metallurgical control, CNC-based production, and rigorous quality assurance protocols tailored to defense-grade hardware. The contractor has delivered products exclusively to the Department of Defense, indicating a focused relationship with military procurement channels that require certified ordnance components for small arms platforms. This engagement suggests alignment with Army, Marine Corps, or Special Operations procurement needs for rifle and machine gun barrel assemblies, where performance under sustained fire and environmental stress is paramount. Operating under NAICS 332994, Bartlein Barrels operates within the small arms and ordnance accessories manufacturing vertical, serving a highly specialized segment of the defense industrial base. Their market positioning is that of a precision manufacturing subcontractor, supporting larger defense prime contractors and government arsenals with critical barrel components rather than complete weapon systems. As a small business structured as a 2L entity, Bartlein Barrels, Inc. is based in Jackson, Wisconsin, with no federal certifications on record. Their geographic presence reflects a regional manufacturing footprint serving national defense requirements through direct contractual engagement with DoD entities. The company’s operational scale and technical focus suggest a lean, specialized production environment optimized for high-quality, low-volume ordnance components.
