Field Tips to Protect Your Firearm in the Rain

Rain is a fact of life for hunters. Whether you're after turkey, big game, small game, predators, or waterfowl, sooner or later, you're going to find yourself in wet conditions. While hunting in the rain can be rewarding, it also presents a challenge: keeping your firearm in top condition. A wet gun is more than just an inconvenience; it can be a safety hazard. Water and moisture can lead to rust, cause malfunctions, and even create dangerous situations if not properly managed. So, let’s talk about how to protect your firearm in the rain while keeping safety a top priority.

Start Dry: Prepare Before the Hunt

One of the simplest yet most effective ways to protect your firearm in rainy conditions is to start with a clean and dry gun. Before heading out, wipe down your firearm with an oiled cloth, making sure all metal surfaces have a thin protective layer. This not only helps repel water but also prevents rust from forming the moment moisture makes contact.

If you know rain is in the forecast, consider applying a bit of extra protection to the most exposed areas. Pay special attention to the receiver, action, trigger guard, and barrel. A quality gun oil or rust-preventative spray can add an extra layer of defense. However, don’t overdo it—too much oil can attract dirt and debris, which can lead to other issues down the line.

Keep an Oiled Rag in a Ziplock Bag

When you're in the field, conditions can change quickly. That’s why it’s always a good idea to carry an oiled rag in a ziplock bag with your hunting gear. This small and simple trick can save your firearm from unnecessary moisture damage.

If your gun gets wet during your hunt, take a quick moment to wipe it down with your oiled rag before the moisture has time to settle in. Pay special attention to the barrel and action, as these areas are the most vulnerable. Keeping an oiled cloth handy ensures you can provide on-the-spot maintenance without carrying a full cleaning kit into the woods.

Tape Over the Muzzle to Prevent Water Intrusion

One of the most effective ways to prevent water from entering your barrel is to place a small piece of electrical or duct tape over the muzzle. This simple trick keeps rain, snow, mud, and debris out of the bore without affecting your shot.

A common concern among hunters is whether shooting with tape on the barrel will impact accuracy or safety. The good news? It won’t. When you fire, the air pressure inside the barrel blows the tape off before the bullet exits, ensuring no interference. For added peace of mind, many seasoned hunters swear by this trick and use it in all kinds of wet conditions.

Protecting Wooden Stocks and Synthetic Firearms

If you hunt with a firearm that has a wooden stock, be aware that moisture can cause the wood to swell, affecting accuracy and function. Consider applying a quality wood sealant or wax to help repel water. For synthetic stocks, a simple wipe-down with a water-resistant silicone cloth can keep moisture at bay. Regardless of the material, ensure that any sling attachments, recoil pads, and grips are checked for trapped water after the hunt.

Post-Hunt Maintenance: Dry, Clean, and Oil ASAP

Once you’re back from your hunt, don’t delay cleaning your firearm. Moisture can start causing damage in as little as a few hours, so a thorough teardown and cleaning session should be a top priority.

1. Wipe It Down – Use a dry cloth to remove all visible moisture from the exterior of the gun, including the stock and barrel. If your firearm was exposed to heavy rain, remove the stock (if possible) to ensure no moisture has seeped underneath.

2. Clean the Bore – Run a dry patch through the barrel to remove any water or condensation. Follow up with an oiled patch to prevent rust formation.

3. Check Screws and Moving Parts – Water can settle in tiny crevices, causing rust to develop on screws, bolts, and small moving parts. Loosen screws to ensure no moisture is trapped underneath, then re-tighten after drying.

4. Lightly Oil All Metal Surfaces – Once the firearm is dry, apply a light coat of oil to all metal surfaces. This adds a protective barrier against future moisture and corrosion.

Storage Considerations for Wet Weather Hunting

After your firearm is cleaned and dried, proper storage is the final step to ensure long-term protection. Avoid immediately locking your gun in a case, as residual moisture can become trapped inside. Instead, let it sit in a dry, ventilated area for several hours before storing it away. Consider using a dehumidifier or silica gel packs in your gun safe to prevent condensation buildup over time.

Additional Pro Tips for Hunting in the Rain

• Use a Waterproof Gun Case or Sleeve: A soft waterproof gun sock or a hard case with a seal can keep your firearm protected while hiking in rainy conditions.

• Avoid Resting Your Gun in the Dirt or Grass: Even if it's not actively raining, the ground holds moisture that can transfer to your firearm.

• Bring a Small Towel or Chamois Cloth: This can help wipe away excess moisture more efficiently than a standard cloth.

• Store Your Firearm in a Dry Place: After your hunt and cleaning session, let your gun air out in a cool, dry place before locking it away in a safe or case.

• Be Mindful of Temperature Changes: Moving from cold, wet conditions to a warm cabin or truck can cause condensation inside your firearm. Let it gradually adjust before cleaning.

Safety Above All

Keeping your firearm in top shape during wet conditions isn't just about preventing rust—it’s a key part of firearm safety. A neglected, moisture-damaged gun is more likely to malfunction, and any malfunction increases the risk of an accident. Regular maintenance and proactive protection ensure that your firearm remains reliable and safe to use in all conditions.

Hunting in the rain can be an incredible experience, offering unique opportunities to track game when other hunters might stay home. With a little extra preparation and post-hunt care, your firearm will be ready to perform when you need it most, rain or shine.
