Bore Tech C4 Carbon Remover 473ml
The Bore Tech C4 Carbon Remover is a specialized bore cleaner designed specifically for removing stubborn carbon fouling. While the Eliminator handles both copper and carbon, the C4 is purpose-built for situations where heavy carbon buildup is the primary concern. The formula is ammonia-free, biodegradable, and safe for all common barrel steels.
Where ordinary cleaners fall short, the C4 delivers
Carbon buildup in the throat area, on AR bolt tails, in gas systems, and on flash suppressors is notoriously difficult to remove. The C4 employs an advanced combination of surfactants, penetrants, and chemical agents that break baked-on carbon free from the metal surface. This makes the C4 ideal for heavy-duty applications where standard bore cleaners cannot keep up.
More than just a bore cleaner
The C4 is not limited to cleaning the bore. You can also use it on the outside of the barrel, on revolver cylinder faces, compensators, gas pistons, and any other component where extreme carbon fouling accumulates. This versatility makes it particularly valuable for shooters running semi-automatic rifles, revolvers, or pistols with gas systems.
Neutralizes corrosive residues
An additional benefit of the C4 is its ability to neutralize and remove corrosive residues from surplus ammunition and black powder. This protects your bore against the aggressive chemical compounds released by these types of ammunition. After cleaning, the C4 provides short-term rust protection for approximately two weeks under normal storage conditions.
Recommended cleaning procedure
1. Wet 3-4 patches with C4 Carbon Remover and push them individually through the bore to remove loose fouling. Always in one direction only.
2. Make 10-15 passes with a tight-fitting Bore Tech nylon brush saturated with C4.
3. Repeat step 1 and let the C4 soak for 5-10 minutes. For stubborn fouling, extend the soak time.
4. Push dry patches through the bore until they come out clean.
5. For storage, apply a lightly dampened patch with C4 for short-term rust protection, or use Shield XP Rust Preventative for long-term protection.
When to choose C4 versus Eliminator
Use the Eliminator as your everyday all-round cleaner for both copper and carbon after a regular range session. Reach for the C4 when dealing with stubborn baked-on carbon in the throat area, on gas components, or after intensive firearm use. The two products complement each other perfectly: C4 first for heavy carbon, then Cu+2 Copper Remover for copper fouling.
