Dewey 13'' Rod Guide, .338

The Dewey 13'' Rod Guide in .338 is a chamber protector designed to replace your bolt during rifle cleaning, safeguarding your action from solvent splash and bore debris. If you're running longer optics—varmint scopes, target scopes, or precision hunting setups—this extended 13-inch guide gives you the clearance you need to work the rod comfortably without fighting your glass. It's built for shooters who take gun maintenance seriously and want to keep solvent out of the action, trigger group, and magazine well.

The aluminum collar features a threaded brass adjustment pin that lets you dial in the fit for your specific action length in seconds, so setup is fast and repeatable. A rubber O-ring seal handles the dirty work, containing solvent and preventing contamination where it matters most. Just remember: you'll need a cleaning rod that's at least 13 inches longer than your barrel length to use this guide properly.

Whether you're cleaning a .338 after a long range session or running routine maintenance between hunts, this rod guide takes the guesswork and mess out of the process. It's the kind of small-but-essential tool that separates deliberate gun care from wishful thinking.
