Dewey Heavy Duty Muzzle Bore Guide Ruger 10/22 Factory Barrel

As the muzzle end of the barrel is the last place to see the exit of the bullet, it is important to keep this area free from harm. When placed over the muzzle, these guides allow cleaning rods to go straight into the barrel while protecting the muzzle area. The rod passes thru an oilite bushing which is pressed into the Delrin body. The Dewey Delrin Muzzle Bore Guides can be used with all types of cleaning rods. Some models have milled cuts to allow for sight clearance. Designed for the year-round shooter. Designed to keep cleaning rod centered in bore and protect the barrel crown when it is not possible to clean the firearm from the breech. Can be used with coated and non-coated cleaning rods. These guides are firearm-specific and may have milled cuts to allow for sight clearance. FeaturesHeavy Duty Delrin Construction
