Threaded Bushing 2-1/4 x 5/8 -18

The Threaded Bushing 2-1/4 x 5/8 -18 from HOWE is a precision-engineered component built for demanding tactical and military applications where barrel-to-receiver interfaces demand absolute reliability. This threaded bushing serves as a critical coupling element in modular firearm systems, suppressors, and specialized weapons platforms where repeatable headspace and concentricity are non-negotiable. Whether you're building a precision rifle, retrofitting a suppressor host, or assembling a duty weapon, this bushing ensures that threaded connections maintain zero-shift integrity under sustained fire and field conditions.

Manufactured to exacting tolerances, the 2-1/4 x 5/8 -18 bushing features a 5/8"-18 thread pitch—a standard specification widely adopted across modern suppressor interfaces and quick-detach systems. The 2-1/4-inch outer diameter provides substantial bearing surface for load distribution, while the precision-ground threads ensure flush seating and eliminate wobble during installation and firing cycles. The compact 0.31-pound weight and 2.95-inch length make this bushing suitable for compact tactical builds without adding unnecessary bulk, while its durable construction handles thermal cycling and corrosive field environments without degradation.

Professional armorers, weapons engineers, and tactical operators rely on HOWE bushings for suppressor mounting, barrel threading, and modular weapon system assembly where failure is not an option. Installation requires careful alignment to prevent cross-threading; use appropriate wrenches or vises with soft jaws to avoid damage to external surfaces. This bushing is compatible with any platform or suppressor system designed around 5/8"-18 threading, making it an essential spare component for weapons maintenance kits and precision build libraries.
