The Dewey Adjustable Bore Saver Cleaning Rod Guides.
The guide allows the cleaning rods to go straight into the bore without harming the chamber or throat.
ABS Rod Guides are made from anodized aluminum, and available in 5 sizes. The guide also features a solvent port for adding your favorite cleaning chemicals, a rod guide collar with a threaded brass adjustment pin that allows for quick adjustment to any bolt length and chamber sealing o-rings eliminate solvents from coming back into the action, trigger group and magazine areas. On some makes, the bolt stop can be used to retain the rod guide by using the groove provided on the guide collar. They can be used with all types of cleaning rods.
Please see manufacturers website for more details.
ABS models are not compatible with WSM models, but can be modified to fit.
