The OST – Carbon Scraper is a compact carbon scraping cleaning tool. It works on pistols and rifles in many modern calibers. It scrapers carbon buildup from the back of a bolt, inside a bolt carrier, between locking lugs and around a firing pin. It has a pick to aid in disassembly and for cleaning under an extractor. One of the most unique attributes about the scraper is that it was designed to be secured to a single loop of MOLLE webbing with a supplied loop of shock cord. The OST Carbon Scraper is made of precision ground stainless steel, laser cut and nitride treated black. With its compact size and weighing 0.7OZ, it’s a great stand alone cleaning piece or a great addition to your cleaning kit.
