Will the Pro-Shot BG5 bore guide work with my semi-automatic .17 HMR rifle or lever-action platform?

No, the BG5 is specifically engineered for standard bolt-action rifles where the bolt can be fully removed. It is not designed to fit semi-automatic AR-style platforms, which require a dedicated guide like the Pro-Shot BGAR15, nor is it compatible with lever- or pump-action receivers.

Can I use this .17 calibre bore guide if I also shoot .22 calibre rifles?

No, this model is explicitly designed for .17 calibre rifles such as .17 HMR, .17 Hornet, and .17 Fireball. Using it on larger calibres like .22 is not recommended because the inner diameter will not accommodate thicker cleaning rods, meaning you would need to step up to a larger Pro-Shot bore guide model.

Does this cleaning accessory require any electrical safety certifications or a 240V plug for use in Australia?

As a purely mechanical and non-electrical gunsmithing tool weighing approximately 100 g, the Pro-Shot BG5 does not require 240V mains power, an Australian power plug, or electrical safety certifications such as SAA or RCM.

How does the adjustable brass pin mechanism operate during routine bench cleaning?

The BG5 features an anodised aluminium sleeve equipped with an adjustable brass pin mechanism that allows you to lock the guide securely into different action lengths. This setup properly aligns and centres your cleaning rod to protect delicate rifling while preventing harsh bore-cleaning solvents from leaking into your trigger mechanism and magazine well.

17 Cal Bore Guide - Pro-Shot BG5

The Pro-Shot "Stopper" Series .17 Calibre Adjustable Bore Guide (Model: BG5) is a rifle cleaning bore guide engineered specifically for .17 calibre bolt-action rimfire and centerfire rifles. Replacing the bolt assembly during maintenance, it properly aligns narrow, bend-sensitive cleaning rods with the bore to prevent damage to the chamber, rifling, and bore throat. It also seals the chamber cavity to block harsh chemical solvents, carbon, and copper debris from entering the trigger mechanism, magazine well, and action.

Key Features

Chamber and Throat Protection: Centers cleaning rods directly down the bore axis to eliminate rod flex and rubbing against internal rifling.
Solvent Isolation: Bridges the receiver cavity to keep aggressive cleaning chemicals and fouling out of the rifle's internal action and trigger assembly.
Integrated Solvent Port: Features a rear solvent port allowing direct application of bore cleaner onto cleaning patches without chemical spills.
Durable Chemical-Resistant Build: Constructed with an aircraft-grade anodised aluminium sleeve, CNC-machined Delrin tip and collar, and an adjustable brass locking pin.
Adjustable Fit: Features an adjustable locking collar mechanism to fit varying bolt-action receiver lengths securely.

Specifications

Calibre Compatibility: .17 Calibre (.172 bore, including .17 HMR, .17 Mach 2, .17 Hornet, .17 Fireball)
Action Compatibility: Bolt-action rifles with removable bolts
Materials: Anodised aluminium tube, Delrin tip/collar, brass locking pin
Unit Weight: Approximately 100 g (0.1 kg)
Packaged Dimensions: Approximately 25 × 10 × 5 cm
Operation: Manual / mechanical (non-powered)

Who is the Proshot 17 Cal Bore Guide for?

Vermin hunters shooting .17 HMR and .17 Hornet bolt-action platforms — requires a dedicated rifle cleaning bore guide sized precisely for .17 calibre barrels to prevent narrow, flexible cleaning rods from bowing and scraping the delicate bore throat during field maintenance.
Small-game hunters performing precision bench cleaning on .17 calibre rifles — benefits from a lightweight 100 g bore guide that seals the receiver against aggressive bore solvents while accurately centering the rod through its chemical-resistant Delrin components.

Less suitable for: Calibres larger than .17 (such as .22 to .30 cal), which exceed the internal diameter threshold and require a larger-diameter multi-calibre bore guide, as well as semi-automatic AR-style platforms or lever/pump-action receivers that require platform-specific receiver cleaning guides.
