What is the BORE TECH - C4 CARBON REMOVER?

Technologically advanced, 100% biodegradable formula is environmentally safe, yet strong enough to remove the toughest carbon, lead, and moly fouling in just seconds. Ideal for rifle barrels, bolt faces, flash suppressors, compensators, silencers, chamber throats, revolver cylinders, gas pistons and any other place extreme carbon fouling is found. Will also neutralize and remove corrosive salts found in surplus military ammunition and black powder. Deep cleaning action easily penetrates the smallest crevices and other hard-to-reach areas, leaving heavily fouled parts looking factory new. For really stubborn fouling just soak in C4 Carbon Remover for a few minutes, then wipe or patch dry. Conditions the metal to help prevent future build-up. Non-flammable, ordorless, ammonia free solution is safe for indoor use.

SPECS: 4 fl. oz. (118 ml) squeeze bottle or 16 fl. oz. (473 ml) plastic bottle.

Best for carbon ring
This stuff really works! Best thing I’ve found to get rid of carbon ring and fouling in chambers of CF guns.

best for gas semi-auto piston
The gas piston of my Fabarm L4S always gets heavy carbon deposits, I keep a jar full of C4 and use it to soak the piston while I clean the bore with C4 on a patch until it is clean. When I take the gas piston back out after soaking carbon wipes off easily with a paper towel.

c4
Ive been using this product for two years now. I was using rimfire blend while shooting bench rest matches and my rifles just starting dropping out. I tried everything under the sun to get the carbon build up out. I was at my witts end with it. Im suprised my bore didnt stroke out after all the chemicals i put into it for carbon cleaner. I tried c4 and i kid you not in two sessions of applying it as directed on the bottle i was back to the metal. I now carry it only to the matches with me when im cleaning on the bench. I know for a fact i will not start dropping points because of carbon.

Removes the ring
Works well for removing the carbon ring build up in my 22lr bench rifles. Noticable improvement in accuracy.

Carbon Remover removes carbon!
Used this on a Remington 700 .308 that hadn't been cleaned in about 400 rounds. Had stubborn carbon deposits in all of the grooves, particularly the throat area. Tried a number of other solutions and methods that just wouldn't budge the carbon. THIS budged the carbon! Followed the instructions on the label - did it twice - and the bore is now bare down to the steel. Very impressed. Will be part of my cleaning regimen going forward.
