The number one cause of extraction/ejection problems with AR-pattern rifles is excessive chamber fouling. The new Star Chamber Cleaning Tool from Otis Technology ($29.99) makes the otherwise awkward and difficult job of thoroughly cleaning AR chambers a quick and simple proposition. Available for both 5.56 NATO and 7.62 NATO AR chambers, it features a Parkerized steel scraper to remove built-up fouling, plus felt cleaning pads to pick up the fouling loosened by the scraper. A coated brass nose piece centers the tool in the chamber and ensures that it won’t be scratched or damaged. The tip of the tool is tapped with 8-32 threads for attachment of a chamber cleaning brush or other cleaning accessories for added versatility. It comes with six felt cleaning pads, and extra pads are available priced at $5.99 per dozen. Contact Otis Technology, Dept. OT; Tel.: (800) OTISGUN; Web:

Frank Devlin, national sales manager for Otis Technologies cleaning products, describes the Otis Star Chamber Cleaning Tool, introduced at the 2015 SHOT Show. The Otis Star Chamber Cleaning Tool should be available in the first half of 2015 in both 5.56 NATO/.223 Rem. and 7.62 NATO/.308 Win. versions. It makes cleaning your AR a little easier, with an extendable shaft that makes it easier to reach into the chamber. Use the scraper head to remove fouling. Once the residue has been scraped off, remove the remainder using a felt star pad soaked with your choice of cleaner. The Star Chamber Cleaning Tool’s 8-32 threads can also accept other brushes.
