For precision shooters who demand a spotless bore without shortcuts, the Hoppes No.9 Benchrest Copper Solvent 5oz is a chemically aggressive, non-abrasive bore cleaner formulated specifically with the benchrest and target shooting community in mind. Where standard solvents might leave trace copper behind after multiple passes, Hoppes Benchrest gets to work overnight, dissolving heavy copper deposits, carbon buildup, lead, and plastic fouling back to bare steel through pure chemical action rather than mechanical abrasion. This means your barrel geometry stays intact, your throat and crown remain unaffected, and your accuracy baseline stays consistent from session to session. Safe across all bore types including stainless steel, chrome-lined, and lapped match barrels, this is a solvent you can trust in your most prized rifles, shotguns, and handguns.

Hoppes No.9 Benchrest Copper Solvent 5oz Key Features

• Overnight copper dissolution: The formula works on contact and can be left in the bore overnight to fully break down even the heaviest copper fouling, eliminating the need for multi-day soaking that some competing products require.
• Full-spectrum fouling removal: Removes copper, powder, lead, and plastic fouling in a single chemical process, making it suitable for centrefire rifles, slug guns, and handguns across varied shooting disciplines.
• Non-abrasive chemical action: Fouling is dissolved rather than scrubbed away, which preserves the precision geometry of lapped match barrels and fine-tolerance bores where even minor abrasion can affect group size.
• Restores barrel to bare steel: Unlike general-purpose solvents that leave residual fouling layers, Benchrest is designed to strip the bore completely, giving you a true clean-slate baseline for accuracy testing and load development.
• Compatible with all bore types: Safe for use in stainless steel, chrome-lined, and lapped match barrels, making it a single-product solution regardless of the firearm in your cleaning kit.
• Brush compatibility: Use with nylon or stainless steel brushes only. Bronze brushes should be avoided as the solvent will react with and dissolve the brush material, giving a false positive reading of copper removal.
• Neutralise after use: Always follow up with a quality bore oil or lubricant after cleaning to neutralise the solvent and protect the barrel from corrosion. This is a standard and critical step in any bore cleaning routine.
• Packaging: Supplied in a 5 oz (approximately 148ml) plastic bottle, model BR904.

Whether you are chasing sub-MOA groups at the range or keeping a working hunting rifle in peak condition, Hoppes Benchrest Copper Solvent takes the guesswork out of bore cleaning. It is a straightforward, chemically proven product that does exactly what it claims, without damaging your barrel in the process.
