Mandrel Sleeve - Cam Installation Tool

The Mandrel Sleeve – Cam Installation Tool by DURA-BOND is a precision-engineered component designed for armourers, gunsmiths, and tactical professionals who require reliable cam installation on AR-pattern rifles and bolt-action firearms. This compact tool addresses a critical need in rifle assembly and maintenance: accurate, repeatable seating of cam pins and related components without marring or misalignment.

Manufactured by DURA-BOND, a brand trusted in the tactical and industrial sectors, the Mandrel Sleeve delivers precision through its engineered geometry and robust construction. The sleeve design protects both the installation surface and the component being installed, reducing the risk of damage during assembly—a critical factor when working with AR-15 lower receivers, bolt carrier groups, or other precision-fitted assemblies.

Armourers, gunsmiths, and firearm builders across law enforcement and military sectors will find this tool invaluable for maintaining inventory in an armory or running a high-volume gunsmithing operation. The calibrated tolerances ensure that installers achieve proper interface fit without excessive force, which can compromise material integrity or cause costly rework.
