A Remington 870 can stay smooth, reliable, and ready for decades if it gets the right care between range trips and seasons. The good news is that long life usually comes down to simple habits, not complicated gunsmith work. These nine storage and maintenance practices help protect finish, prevent wear, and keep this classic pump shotgun feeling almost new after 20 years.
Start With a Consistent Cleaning Routine
The easiest way to make a Remington 870 last is to clean it on a schedule instead of waiting until it looks dirty. Powder residue, plastic fouling, and moisture can build up quietly, especially after long days at the range or in the field. A quick post-use wipe-down plus a more thorough cleaning every few outings goes a long way.
Consistency matters more than intensity. You do not need to strip every part after every box of shells, but you do want to remove grime before it hardens or traps moisture. Over years of use, that simple habit preserves smooth cycling and helps small issues show up before they become expensive repairs.
Keep the Bore Clean and Lightly Protected
The barrel does a lot of quiet work, and it deserves regular attention. Fouling inside the bore can affect performance over time, while moisture left behind after cleaning or hunting can invite rust where you may not see it right away. Running the proper brush and patches through the barrel keeps things simple and effective.
After the bore is clean, a very light protective film is usually all you need for storage. Too much oil can attract debris or migrate where it should not. The goal is not to leave the barrel wet, but to leave it clean, dry enough for safe use later, and guarded against the kind of corrosion that slowly ages a shotgun.
Use Lubrication Sparingly in the Right Places
One of the most common maintenance mistakes is over-lubrication. A Remington 870 does benefit from oil on key contact points, but excessive lubricant can collect dust, unburned powder, and pocket grit from a gun case or hunting bag. Over time, that sticky mix can make the action feel heavier instead of smoother.
A light touch is usually best on the action bars, bolt rails, and other friction surfaces. Wipe away any visible excess so the shotgun is protected without becoming a magnet for grime. This is especially important if the gun moves between cold weather, warm interiors, and storage, where oil can thicken, migrate, or trap moisture in ways that work against you.
Pay Attention to the Magazine Tube and Follower
The magazine tube is easy to overlook because it is tucked out of sight, but it plays a big role in reliable feeding. Dust, old oil, and residue inside the tube can slow the follower or create uneven spring pressure. That can lead to frustrating hiccups that feel mysterious until you open things up and inspect the parts.
Cleaning the tube occasionally and checking the follower for rough movement helps keep the gun dependable. It is also smart to inspect the spring for obvious fatigue if the shotgun has seen heavy use over many years. A clean, smooth magazine system helps the 870 do what it is known for, which is feeding shells with calm, workmanlike reliability.
Store It in a Dry, Stable Environment
Where you store a Remington 870 matters almost as much as how you clean it. Basements, garages, sheds, and uninsulated closets often bring swings in humidity and temperature that encourage rust, wood swelling, and finish wear. A shotgun can look fine one month and start showing orange freckles the next if storage conditions are poor.
A dry safe or indoor cabinet with stable air is a much better long-term home. Adding humidity control helps even more, especially in damp regions. Soft cases are useful for transport, but they are not ideal for long storage because they can trap moisture against metal surfaces. Good storage keeps the gun from aging when it is not even being used.
Wipe Down Metal After Every Handling Session
Even if you do not fire the shotgun, your hands leave something behind. Skin oils, sweat, and salts can slowly mark blued steel, especially on the receiver, barrel, and magazine tube where people naturally grip the gun. The damage usually starts subtly, then becomes the kind of finish wear owners wish they had prevented earlier.
A quick wipe with a clean cloth after handling is one of the smartest low-effort habits you can build. If the shotgun has been out in rain, snow, or humid air, that wipe-down becomes even more important. It takes less than a minute, but repeated over years, it can preserve the appearance and corrosion resistance of the entire gun.
Check the Stock and Forend for Cracks or Looseness
Wood and synthetic furniture both deserve occasional inspection. With wood stocks, small cracks near stress points can grow if moisture, recoil, or storage pressure keeps working on them. Synthetic parts can loosen too, especially after years of hard use, temperature changes, and repeated disassembly for cleaning or transport.
Take a close look at the stock, recoil pad, and forend from time to time, and make sure everything feels solid in the hands. Catching a hairline crack or a backing-out fastener early can save a bigger repair later. It also helps the shotgun maintain that tight, confidence-inspiring feel that owners often associate with a well-kept 870.
Inspect Small Parts Before They Become Big Problems
The Remington 870 has a reputation for toughness, but like any hardworking machine, it relies on small parts that wear gradually. Pins, springs, extractors, and shell latches do not usually fail without warning. More often, they show clues first, such as rough cycling, weak extraction, or a change in how the action feels under the hand.
A periodic inspection helps you notice those clues before they interrupt a hunt or range day. You do not need to become a full-time tinkerer, just a careful observer. Replacing a worn spring or addressing a part that is starting to drift can keep the shotgun dependable and prevent secondary wear to surrounding components.
Avoid Long-Term Storage With Tension and Moisture
Long storage is not just about putting the shotgun away and forgetting it. If it is stored in a damp space, inside a moisture-holding case, or with old grime still on the metal, time starts working against you. Likewise, leaving components under unnecessary tension for years is not ideal when a little preparation can reduce stress and preserve condition.
Before storing the gun for a season or longer, clean it properly, apply light protection, and choose a dry location with airflow control. Then check on it occasionally rather than assuming all is well. That small amount of attention can stop rust, spotting, and sluggishness from developing quietly while the shotgun sits unused.
