The Dewey Cleaning Rod Guide for AR-15/M16 is a model-specific cleaning guide from Dewey (listed under part number AR6.8), machined to index directly off the AR-15/M16’s own receiver or muzzle contours. A generic universal guide often rocks or seats poorly against a specific rifle’s actual dimensions, which lets a cleaning rod drift and scrape metal it shouldn’t touch. This guide is cut to the AR-15/M16’s exact geometry instead, so the rod tracks straight through the bore every time. It’s the kind of small, model-specific accessory that’s easy to overlook until a generic guide damages a barrel or receiver it wasn’t actually built for. Pick up a matching rod and brush from our gun cleaning supplies lineup to complete the setup.

Key Specifications

• Bore diameter is sized for AR-15/M16 6.8MM, so the fit is snug against the rifling instead of the sloppy pass-through of an oversized brush or rod.
• Machined to fit the AR-15/M16 specifically, rather than a generic one-size part that fits loosely.
