A bore guide is one of the best investments you can make in your cleaning routine—it protects your rifle's chamber and bore from the wear and abrasion that comes with pushing a cleaning rod through thousands of times. The Lyman Universal Bore Guide Set is built to work across most bolt-action rifles and AR-15s, so you're not buying multiple guides for different firearms. Machined from anodized aluminum and engineered for precision, this set handles calibers from .17 to .416, with interchangeable tips that let you match the guide to whatever you're cleaning that day.
The design details here matter. The thread-on nozzles won't stick or bind in your chamber like press-fit designs can, and the machined solvent port lets you apply cleaner to your patch without the mess of trying to force a wet patch into an open-ended guide. If you run an AR-15 platform, a dedicated adapter sleeve is included—no improvising or worrying about fit. Works with standard cleaning rods, jags, and brush sets, so it integrates into your existing cleaning kit without requiring a complete overhaul.
Whether you're a hunter running routine maintenance between seasons, a competitive shooter maintaining match-grade accuracy, or someone who simply respects their gear enough to clean it properly, a bore guide is non-negotiable. The Lyman Universal set removes guesswork and protects the two most critical parts of your rifle's accuracy equation: the chamber and the bore.

Frequently Asked Questions
Will this bore guide fit my AR-15?
Yes. The set includes a dedicated adapter sleeve specifically designed for AR-15 platforms, so you're covered for modern tactical rifles as well as traditional bolt-actions.
What calibers does the Lyman Universal Bore Guide cover?
The interchangeable tip system covers .17 to .416 caliber rifles, which covers the vast majority of hunting and shooting applications from varmint to magnum calibers.
Will this work with my existing cleaning rod?
The Lyman Universal Bore Guide is designed to work with most standard cleaning rods, including Lyman's Universal Cleaning Rod System, jags, and brush sets. If you're using a quality aftermarket rod, it should be compatible, but verify the rod diameter with your system.
What's the advantage of the solvent port design?
The machined-in solvent port lets you apply cleaner directly to your patch while it's seated in the guide—no more awkwardly trying to force a wet patch into an open end. It's a cleaner, more controlled process that reduces mess.
