4in Straight Tube 4in Long

The 4in Straight Tube 4in Long is a precision-engineered aluminum component designed for builders, fabricators, and tactical system integrators who demand reliable tubing solutions. This polished aluminum tube serves as a foundational structural element in custom rifle builds, airflow systems, suppressor assemblies, and equipment housings where dimensional consistency and material integrity are non-negotiable. Whether you're constructing a precision firearm component, assembling pneumatic systems, or engineering a custom accessory, this straight-wall tubing provides the dimensional accuracy and material quality that professional-grade projects require.

Manufactured from high-grade aluminum with a polished finish, the 4in Straight Tube features a 4-inch outer diameter and 4-inch length, making it ideal for mid-range component applications. The polished surface treatment enhances corrosion resistance while maintaining a professional appearance, and the lightweight aluminum construction (0.65 lbs) minimizes overall system weight without sacrificing structural rigidity. Aluminum's excellent machinability allows for secondary operations—threading, boring, milling, or custom port drilling—enabling engineers and builders to customize the tube to specific application requirements without material failure or tool wear complications.

This component is ideal for armourers, gunsmiths, and OEM manufacturers integrating tubing into suppressor designs, upper receiver assemblies, or modular firearm systems. The compact 4 x 4.5 x 7-inch footprint facilitates inventory management and shipping efficiency, while the straight geometry eliminates complexity in assembly sequences. Machinists and fabricators benefit from the dimensional stability of polished aluminum, which resists binding during precision boring and threading operations. For those sourcing tactical-grade tubing for sale, review, or custom build specifications, this SPECTRE-manufactured tube delivers repeatable tolerances and material consistency that professional standards demand.
