Duration: 25:41

This guide details the proper care and lubrication of over/under shotguns, emphasizing the critical importance of avoiding oil on wood components. It covers disassembly, bore cleaning techniques using various tools like bore snakes and brushes, choke tube maintenance, and precise lubrication points on engagement pins and lugs. The guide also includes essential steps for reassembly, preventing dry-fire damage with snap caps, and proper storage procedures to maintain the shotgun's integrity and longevity.

Quick Summary

Avoid oiling the wood components of your over/under shotgun receiver, as the end grain will absorb it like a sponge, leading to degradation. Use lubricants sparingly, applying only a single drop to critical points like choke threads, receiver pins, and lugs, and always wipe off excess to prevent migration into the wood.

Frequently Asked Questions

Why should I avoid oiling the wood on my over/under shotgun receiver?

The wood in the receiver inlet areas of over/under shotguns is end grain, which absorbs oil like a sponge through capillary action. This can quickly degrade and damage the wood, compromising the firearm's integrity and value.

What is the best way to clean the bore of an over/under shotgun?

You can use a traditional cleaning rod with a patch and solvent, a bronze bristle brush, or a bore snake. Always clean from the breech end. For stubborn fouling, a bristle brush is effective, ensuring it passes completely through the bore.

How much lubricant should I use on my shotgun's internal parts?

Use lubricant very sparingly. For critical points like choke tube threads, receiver pins, and locking lugs, a single drop is sufficient. Always wipe off any excess to prevent oil from migrating into unwanted areas, especially the wood.

Can I dry fire my over/under shotgun?

It is generally not recommended to dry fire most over/under shotguns without snap caps. Dry firing can damage the firing pins and the breach face over time by causing them to cup and wear down.

How should I store my over/under shotgun when disassembled?

When storing disassembled, ensure the top lever is not cocked to avoid stressing the springs. You can relax the lever tension by depressing a specific pin in the receiver while moving the lever to the open position.
