The Bisley Wire Shotgun Cleaning Loop for 12 gauge is a simple cleaning accessory designed to hold cloth patches on a cleaning rod. It screws onto the end of a standard shotgun cleaning rod and forms a flexible wire loop that you thread a cleaning patch through. Once fitted, the patch is pulled through the barrel to remove loose fouling, powder residue, plastic wad deposits, and light dirt left after shooting.

Unlike rigid jags or brushes, the wire loop is adjustable because the patch is not fixed tightly in a solid holder. This makes it useful when you want a gentler, more flexible cleaning pass through the barrel, especially during routine maintenance rather than heavy scrubbing. It is commonly used after brushing the barrel, acting as a final cleaning step to wipe out remaining residue and distribute oil evenly inside the bore.

The loop is designed specifically for 12 gauge shotguns, meaning it is sized to match the larger bore diameter compared to smaller gauges. It is typically made from durable steel wire, chosen for its balance of strength and flexibility. The material is soft enough not to damage the barrel if used correctly, while still being rigid enough to pull patches through effectively.

This type of tool is not a full cleaning system on its own, but part of a basic cleaning setup. It is best suited for regular upkeep after shooting sessions rather than deep cleaning of heavily fouled barrels. Its simplicity makes it reliable and long-lasting, with very little that can wear out or break unless it is bent or misused.
