Tube .875 x 4.5 x 5/8 thread

The U-B Machine Tube .875 x 4.5 x 5/8 Thread (MPN 42-0423-C) is a precision-engineered cylindrical component designed for military and law enforcement weapons systems, suppressors, and tactical accessories. This tube serves as a critical structural or functional element in modern tactical platforms, ensuring reliability in high-stress environments.

Manufactured by U-B Machine to tight concentricity and wall-thickness specifications, the .875-inch outer diameter and 5/8-inch threading provide a robust interface for secure assembly and stress distribution. The 4.5-inch length accommodates both compact and full-length tactical configurations, while the precision thread profile ensures positive engagement without galling or cross-threading during high-cycle use.

Weighing just 0.3 pounds, this component offers minimal weight penalty—critical for weapons-mounted systems where every gram affects handling dynamics and shooter fatigue. Precision technicians, armorer-class gunsmiths, and OEM tactical manufacturers rely on U-B Machine components for suppressor baffles and muzzle devices.
