Carbon fouling is one of the most stubborn enemies of barrel accuracy and long-term firearm condition, and the Bore Tech C4 Carbon Remover 16oz is purpose-built to deal with it head-on. Developed by Bore Tech in the USA, C4 uses a proprietary blend of surfactants, penetrants, suspending agents, and targeted chemical action to quickly loosen and lift carbon deposits from even the most fouled surfaces, without attacking the metal underneath. Unlike a lot of solvents on the market, C4 is completely ammonia-free, non-toxic, non-flammable, and odourless, making it a practical choice for shooters who clean in enclosed spaces or want a more user-friendly product without sacrificing cleaning performance. The 16oz (473ml) bottle gives you plenty of volume for extended cleaning sessions, making it well-suited for high-volume range shooters, hunters running semi-automatics, or anyone dealing with surplus or black powder ammunition residues.

Bore Tech C4 Carbon Remover 16oz Key Features

• Proprietary Surfactant Formula: C4 uses a sophisticated blend of surfactants, penetrants, and suspending agents that work chemically to break the bond between carbon deposits and metal surfaces, lifting fouling efficiently rather than relying on abrasion or harsh solvents.
• Carbon, Copper, and Lead Fouling Removal: Primarily designed as a carbon remover, C4 also reduces copper and lead fouling, making it a versatile cleaner across a broad range of shooting disciplines and ammunition types.
• Neutralises Corrosive Residues: Effectively neutralises and removes the corrosive salts and residues left behind by surplus military ammunition and black powder, which is essential for protecting the bore after shooting these types of propellants.
• Accurate Fouling Assessment: Because C4 is ammonia-free, it does not produce a false blue reaction when used alongside copper-removing solvents, allowing you to accurately assess the actual state of copper fouling in the bore without cross-contamination from your carbon cleaner.
• Universal Barrel Compatibility: Safe for use on blued, stainless steel, and chrome-lined barrels across all calibres and gauges, including precision bolt-action rifles, shotguns, and AR-platform semi-automatics.
• Wide Application Range: Suitable for use on barrels, throats, chambers, AR bolt carriers, flash suppressors, compensators, revolver cylinders, gas pistons, and any other components subject to heavy carbon build-up.
• Built-In Rust Preventative: The formulation includes a rust preventative component, offering a degree of surface protection after cleaning, not just solvent action.
• Non-Toxic, Ammonia-Free, and Odourless: Free from ammonia, BPA, and harsh chemical odours, making it safe and practical to use in workshops, gun rooms, or anywhere with limited ventilation.
• Biodegradable and Environmentally Safe: C4 is biodegradable and environmentally safe, allowing for responsible disposal without the concerns associated with conventional petroleum-based solvents.
• Made in the USA: Manufactured in the USA by Bore Tech, a brand with a long-standing reputation among precision shooters for chemistry-driven cleaning solutions.

Bore Tech C4 Carbon Remover is a serious, chemistry-first cleaning solution for shooters who want effective carbon removal without the trade-offs of ammonia, harsh fumes, or metal-damaging formulas. Whether you are maintaining a precision hunting rifle, keeping an AR bolt carrier running cleanly, or dealing with the corrosive residue of surplus or black powder loads, C4 handles the job in a format that is genuinely safe and easy to work with.
