The DEWEY Adjustable Rod Guides protect the rifle chamber during cleaning by replacing the bolt and sealing out bore solvent with a rubber O-ring.
Features include a long-wearing aluminum rod guide collar with a threaded brass adjustment pin for quick action length adjustment, and compatibility with most centerfire bolt action rifles.
Available in 10" and 13" lengths, the rod guides require a cleaning rod that is 10" or 13" longer than the barrel length and come with spare O-rings and an O-ring assembly tool.
