Upgrading Your Remington 870 With Aftermarket Parts And Accessories
The Remington 870 is one of the most adaptable pump-action shotguns ever made. Its long production history, broad model range, and extensive aftermarket support make it possible to tailor the platform for hunting, home defense, clay shooting, or general range use. The best upgrades, however, are not always the most expensive ones. They are the parts that suit the shotgun’s intended role and improve handling without compromising reliability.
Before ordering accessories, identify the exact 870 configuration you own. Gauge, chamber length, barrel profile, receiver drilling, stock dimensions, and magazine capacity can all affect compatibility. A part designed for a 12-gauge field model may not fit a 20-gauge receiver or a specialized tactical variant.
A practical upgrade project should also account for safe storage, local regulations, and professional installation where needed. The Remington Firearms Store catalog can help you compare compatible firearms, ammunition, and accessories, while its shipping information explains when items must go through a chosen FFL dealer.
Start With The Shotgun’s Intended Role
A field 870 used for upland hunting has different priorities from a short-barreled defensive model. Hunters often benefit from a comfortable stock, a ventilated recoil pad, interchangeable choke tubes, and a barrel suited to the game being pursued. Waterfowl users should pay particular attention to corrosion resistance and weatherproof finishes. This overview of waterfowl shotgun guidance offers useful context when selecting a configuration for wet environments.
For home-defense or security applications, simplicity is usually more valuable than adding numerous accessories. A dependable light, a properly fitted stock, and controls that can be operated naturally may provide more practical value than decorative furniture or excessive rail-mounted equipment. Every addition should serve a clear purpose and preserve access to the action, safety, loading port, and ejection path.
Improve Fit Before Adding Weight
Stock fit is among the most influential upgrades for any shotgun. Length of pull affects how quickly the shooter mounts the gun and how comfortably the trigger can be reached. Adjustable or shortened stocks may help users who wear heavy clothing, while a traditional field stock can provide a steadier cheek weld for hunting and clay targets.
A recoil pad can make extended practice more comfortable, but padding alone does not solve every fit issue. Drop, cast, comb height, and grip shape also affect eye alignment and swing. A qualified gunsmith can help evaluate these dimensions, especially if the 870 will be used with optics or a raised comb. Avoid modifying the stock aggressively without confirming that the change will preserve safe control of the shotgun.
Select A Barrel And Choke For The Job
The barrel is central to the 870’s performance. Longer barrels generally favor a smoother swing and a more balanced feel in the field, while shorter barrels are easier to maneuver in confined spaces where legally permitted. A smoothbore barrel with interchangeable choke tubes provides flexibility for different shot sizes and patterns.
Choke selection should match the ammunition and intended distance. Improved cylinder, modified, and full chokes produce different shot patterns, and the best choice depends on the load, target, and testing conditions. Patterning the shotgun at realistic distances is more useful than relying on a label alone. Use only ammunition and choke combinations approved for the specific barrel.
The following comparison can help organize an upgrade decision:
| Upgrade Area | Best For | Main Benefit | Important Consideration |
|---|---|---|---|
| Recoil pad | Hunting, clay shooting, frequent practice | Greater shooting comfort | Must preserve proper stock length |
| Improved stock | Users needing better fit | Better control and cheek weld | Confirm model and gauge compatibility |
| Interchangeable choke system | Field and sporting use | Flexible shot patterns | Match choke to approved ammunition |
| Weapon-mounted light | Low-light defensive use | Target identification | Check mounting space and activation |
| Sling and swivels | Hunting and practical carry | Easier transport | Avoid interference with controls |
| High-visibility sights | Slugs or defensive practice | Faster sight alignment | Verify mounting and zero |
Add Practical Controls And Sighting Equipment
A sling can make a meaningful difference during hikes, hunts, and training sessions. Choose a design that supports the shotgun securely without blocking the ejection port or creating excess movement. Quality sling swivels are important because a failure while carrying the firearm can damage the gun or create a safety hazard.
Sights should be selected according to the ammunition and distances involved. Bead sights remain simple and effective for many bird-hunting applications. Ghost-ring sights can provide a more defined sight picture for defensive or slug use, while a compact optic may assist users who prefer a more precise aiming reference. Any sight change should be followed by careful zeroing and function checks at a controlled range.
An accessory rail can expand mounting options, but it also adds weight and may alter the balance of the 870. Avoid installing several overlapping systems simply because the receiver or forend has available mounting points. A lighter shotgun is often easier to carry, mount, and manipulate over a full day.
Prioritize Reliability Over Appearance
Aftermarket reliability parts may include upgraded extractors, magazine springs, followers, action components, and shell carriers. These components can be useful when replacing worn factory parts or restoring dependable cycling in an older shotgun. Compatibility is essential because Remington 870 variants have changed across production periods, and some parts are gauge- or generation-specific.
Internal work deserves special caution. A gunsmith should inspect fitting, timing, safety operation, and trigger function after any significant modification. Do not assume that a part marketed as “drop-in” requires no inspection. Confirm that the action opens and closes correctly, the safety works as intended, and the shotgun remains unloaded during all handling and testing.
Routine maintenance often provides a larger reliability benefit than an ambitious parts list. Clean the bore and action according to the manufacturer’s guidance, inspect screws and sling attachments, and check for corrosion after exposure to rain, mud, or humidity. Keep ammunition stored separately and use only cartridges appropriate for the chamber marking.
Match Accessories To Your Training
Accessories are most useful when they support skills that are practiced regularly. A new stock should be mounted and tested with the same clothing and equipment used in the field. A light should be handled safely in a controlled environment, and any optic or sight should be checked after installation and transport.
A balanced upgrade sequence can keep costs under control:
- Confirm the exact 870 model, gauge, chamber, and barrel configuration.
- Improve stock fit and recoil management before adding electronic or tactical accessories.
- Choose a barrel and choke combination that matches the intended ammunition.
- Install only the controls and carry equipment that support a specific use.
- Have a qualified gunsmith inspect major internal, trigger, sight, or receiver modifications.
Comparing the 870 with other Remington platforms can also clarify which features matter most. For example, this semi-auto comparison explains how gas-operated shotguns differ from a pump-action design, helping buyers decide whether the 870’s manual cycling suits their needs.
