The Otis FGRC330 Ripcord offers unparalleled single-pass cleaning that efficiently cleans from Breech-to-Muzzle. Its unique helix shape actively interacts with the rifling throughout the barrel. The Ripcord\'s innovative design includes a molded rubberized core complemented with Nomex fibers, serving dual functions - this design works like a brush to dislodge fouling particles and concurrently operates as a patch to catch them. Furthermore, the Ripcord features brass 8-32 threaded ends, compatible with all Otis cleaning components. Effective heat resistance up to 700 degrees F ensures durability. Specifically designed for .308 cal/7.62mm rifles, this ripcord has a total length of 36 inches.
