The patented Chamber Scraper Tool (CST) is purpose-built to clean the AR-15 star chamber quickly, thoroughly, and without scraped fingers, broken cotton swabs, or improvised tools.

Its expandable scraper teeth reach behind the locking lugs to remove stubborn carbon buildup where brushes and patches struggle to reach. Simply insert the tool, rotate the handle to expand the scraper teeth, clean the chamber, collapse the tool, and remove.

Whether you're maintaining a duty rifle, competition rifle, or range gun, the CST helps keep your firearm running reliably while making chamber cleaning faster and easier.
