Round DOM Steel Tubing 1-3/4in x .120in x 4ft

Round DOM steel tubing 1-3/4in x .120in x 4ft is a precision-engineered structural component built for demanding fabrication, chassis building, and custom assembly work across tactical, automotive, and industrial applications. Designed for builders and fabricators who require dependable material properties and consistent dimensional tolerances, this DOM (Drawn Over Mandrel) tubing serves as a foundation for rifle stocks, equipment frames, mounting systems, and structural reinforcement in law enforcement and military platforms. The 4-foot length provides practical working stock while minimizing waste in typical project builds.

DOM steel tubing is produced through a draw-over-mandrel process that eliminates surface imperfections and delivers superior concentricity and wall thickness uniformity compared to seamless alternatives. The 1-3/4 inch outer diameter with 0.120 inch wall thickness yields a favorable strength-to-weight ratio critical for tactical applications where mass efficiency directly impacts handling and deployment speed. Natural finish steel accepts welding, machining, and finishing operations without surface preparation complications, making it ideal for custom fabricators who integrate tubing into modular or quick-change systems. The material composition supports both MIG and TIG welding protocols standard in professional gunsmithing and equipment manufacturing.

Professional armorers, gunsmiths, and tactical equipment manufacturers rely on DOM tubing for building custom AR platforms, precision rifle stocks, and universal mounting solutions where dimensional consistency and structural integrity are non-negotiable. The 9-pound weight per 4-foot section enables rapid material planning for multi-piece assemblies, while the straightness inherent to DOM production eliminates alignment headaches during machining or welding operations. Fabricators appreciate the compatibility with standard tooling and the predictable machinability that reduces setup time and improves first-pass accuracy on CNC operations.
