Can I use the Pro-Shot 17AD adapter inside my .17 caliber rifle bore?

No, you must never use this adapter inside a .17 or .20 caliber bore. The outer body of the adapter and the #8/32 accessory interface are too large to fit down a .17 or .20 caliber barrel and attempting to do so will cause severe barrel damage. This adapter is strictly intended for cleaning calibers .22 and up, allowing you to use a slender .17 or .20 caliber rod with standard larger accessories.

What thread sizes does the Pro-Shot 17AD rod adapter convert between?

The Pro-Shot 17AD features a #5/40 male thread on the rod interface end to fit standard Pro-Shot .17 and .20 caliber cleaning rods, and steps it up to a standard #8/32 female thread on the accessory end. This precision-machined solid brass fitting lets your slender cleaning rod accept standard .22 to .50 caliber brushes, jags, and patch holders.

Does this brass adapter require any special maintenance or electrical compliance in Australia?

As a passive, non-powered precision-machined solid brass cleaning accessory, 240V power and electrical safety standards such as SAA or RCM certification do not apply. It is fully resistant to standard firearm cleaning solvents and built to withstand workshop and field conditions across the Australian outback without needing complex maintenance beyond wiping it clean after use.

Rod Adapter - Pro-Shot 17AD

The Pro-Shot .17/.20 Cal Rod Adaptor (Model 17AD) is a precision-machined brass fitting designed to step up small-diameter cleaning rod threads to standard accessory thread pitches. It converts a #5/40 male rod thread into a #8/32 female receiver, allowing shooters to mount standard .22 to .50 calibre jags, brushes, and mops onto slender .17 or .20 calibre rods. This configuration enables the use of thinner rods inside tight-bore rifles without purchasing dedicated small-thread cleaning tips.

Key Features

Thread Pitch Conversion: Adapts a #5/40 male rod connection to accept standard American #8/32 threaded cleaning attachments.
Tight Bore Protection: Allows using slim .17 or .20 calibre cleaning rods in tight-tolerance .22 calibre barrels to eliminate rod binding and bore rub while utilising standard .22 calibre accessories.
Solid Brass Construction: Precision machined from bore-safe solid brass to prevent crown, chamber, and rifling damage during pass-through.
Flush Alignment: Manufactured to tight tolerances to maintain straight, wobble-free concentricity between the cleaning rod and accessory.

Who is the Proshot 17/20 Cal Rod Adapter - #5/40 Thread To #8/32 for?

Rimfire match rifle competitors — allows running a slender .17 or .20 calibre rod inside match-chambered barrels with bore sizes of calibre ≥ .22 to prevent rod binding, while stepping the interface up to standard #8/32 female threads for competition-grade brushes and jags using this firearm cleaning rod adapter.
Small-caliber firearm maintenance enthusiasts — connects standard #8/32 male threaded accessories to rods featuring a #5/40 male thread, allowing multi-calibre maintenance setups using existing cleaning tips on barrels measuring calibre ≥ .22.

Less suitable for: Cleaning rifle barrels under .22 calibre (such as dedicated .17 or .20 calibre bores), where the adapter body outer diameter exceeds the bore diameter; direct-threaded #5/40 cleaning accessories without an adapter should be used instead.
