Description
Take the awkwardness and difficulty out of cleaning the chamber area of an MSR/AR style rifle with the use of the chamber cleaning tool.
The OTIS Star Chamber Cleaning Tool FG-2717 is a specialised cleaning device designed for 7.62mm/AR-10 rifles, particularly effective for maintaining the star chamber and locking lug area—critical zones prone to carbon fouling and residue build-up.
This tool features a parkerised steel scraper to dislodge stubborn debris and felt cleaning pads to collect loosened fouling. A coated brass nose piece ensures centred alignment in the chamber without scratching the firearm.
With 8-32 threads, it allows for attachment of additional cleaning accessories like chamber brushes.
Compact and user-friendly, it simplifies one of the most challenging aspects of rifle maintenance, making it a valuable addition to any AR owner’s cleaning kit.
Available in 5.56mm and 7.62mm. Comes with 6 cleaning pads.
