The braided Nomex surface can take up to 700 degree heat, so you can clean it at the range or in the field while the barrel is still hot. Attach a bore brush to get an even more thorough clean. Features 10\" of aggressive cleaning surface; 360 degree cleaning; easy-feed design makes for quicker cleaning from Breech-to-Muzzle and equipped with 5-40 threaded ends to fit Otis limited breech cleaning components.
