17 Cal. Adapter-takes 5/40 Thread To 8/32 Thread

The 17 Cal. Adapter—Takes 5/40 Thread to 8/32 Thread is a precision cleaning accessory engineered for shooters who maintain .17 caliber and .22 rimfire rifles. This adapter bridges the gap between smaller-diameter .17 caliber cleaning rods and standard rifle cleaning accessories, enabling technicians and firearms owners to use conventional #8-32 threaded components on tighter bore applications. For anyone working with precision rimfire platforms or maintaining a mixed caliber collection, this adapter eliminates the need for duplicate cleaning rod sets while maintaining bore safety and tool compatibility.

The adapter functions as a threaded conversion tool, allowing 5/40-threaded .17 caliber cleaning rods to accept industry-standard 8/32 threaded brushes, jags, and patches. Manufactured by Pro-Shot, a trusted name in firearm maintenance tooling, this compact accessory weighs just 0.06 lbs and measures 5 inches in length—fitting easily into any cleaning kit or range bag. The dual-thread design ensures secure seating between rod and accessory, preventing cross-threading or slippage during cleaning cycles and delivering consistent bore contact pressure essential for effective fouling removal in tight-tolerance barrels.

This adapter is ideal for law enforcement armorsmiths, military gunsmiths, competitive rimfire shooters, and hunters who field .17 HMR or .17 WSM rifles alongside larger-caliber platforms. Installation requires no gunsmithing—simply thread the adapter onto your existing 5/40 rod, then attach standard 8/32 cleaning components as needed. The Pro-Shot 17 Cal. Adapter maximizes tool efficiency and extends the service life of your cleaning rod inventory, making it an economical choice for facilities managing multiple calibers or individual shooters seeking simplified bore maintenance solutions.
