Tube .875 x 16 x 5/8 thread

The Tube .875 x 16 x 5/8 thread by U-B MACHINE is a precision-engineered component designed for suppressor assemblies, muzzle devices, and custom firearm builds where controlled gas management and vibration dampening are critical. Built to meet demanding military and law enforcement standards, this tube serves as a foundation for sound suppression systems and flash hider configurations across multiple caliber platforms. Whether you're assembling a modular suppressor stack or fabricating a precision muzzle device, this component delivers the bore diameter and thread engagement necessary for reliable, repeatable performance under sustained fire.

Manufactured to exacting tolerances, the .875-inch outer diameter provides optimal acoustic cavity volume while maintaining structural rigidity under pressure cycling. The 5/8-inch threaded connection ensures secure assembly with standard suppressor end caps and baffles, eliminating rotational drift and maintaining bore concentricity shot after shot. At 16 inches in length, this tube accommodates multiple baffle stacks and sound-reduction chambers, making it suitable for both rifle and large-bore applications. The precision-machined geometry minimizes gas leakage at assembly joints and enables advanced baffling configurations that reduce both muzzle signature and felt recoil impulse.

Armorer-level gunsmiths, suppressor manufacturers, and precision rifle builders rely on U-B MACHINE components for repeatable, combat-proven results. Installation requires standard suppressor assembly tools and threading compatibility verification with your specific end cap and baffle configuration. The 1.07-pound weight distribution contributes to balanced muzzle-heavy systems without excessive point-of-aim shift, critical for marksmen running optics at distance. Verify thread pitch and connection standard before ordering to ensure compatibility with your existing suppressor stack or custom build platform.
