Introduction
The Remington 870 shotgun. Just the name conjures images of law enforcement, hunting trips, and home defense readiness. It’s a legendary firearm, revered for its reliability, durability, and versatility. A staple in gun collections worldwide, the Remington 870 has earned its place as one of the most popular shotguns ever produced. But, for those seeking to personalize their 870, a common question arises: Are All Remington 870 Stocks Interchangeable? The answer, as with many things gun-related, is a bit more complex than a simple yes or no. This guide will delve into the nuances of Remington 870 stock compatibility, helping you navigate the world of customization and ensure a proper fit for your prized shotgun. This guide is designed to help you, the reader, to be an expert when it comes to the compatibility of stocks for your Remington 870 shotgun.
The 870’s legendary status comes from a blend of factors. Its pump-action design is inherently robust, making it less prone to malfunctions than more complex semi-automatic systems. The gun is also relatively inexpensive, compared to many other shotguns, and the ease of use makes it popular for both beginners and experienced shooters alike. It’s a firearm you can depend on in a variety of situations.
One of the most appealing aspects of the Remington 870 is its modularity. Owners can tailor their shotguns to fit their specific needs and preferences, and one of the most common modifications involves swapping out the stock. But with various models, production changes, and aftermarket options, determining if a particular stock will fit your 870 can be tricky.
Remington 870: A Quick Overview
Before diving into the specifics of compatibility, it’s essential to understand the various models of the Remington 870. Each iteration has its own subtle characteristics that influence stock fitment. Some common variants include:
Express
Often considered the workhorse of the 870 family, the Express models are known for their affordability and practicality. They’re widely used by hunters and homeowners.
Wingmaster
A step up in terms of build quality and aesthetics, the Wingmaster series is a favorite among those who appreciate a more refined finish. They often feature higher-quality wood stocks.
Police
Built to withstand the rigors of law enforcement, the 870 Police models are known for their enhanced durability and reliability.
Tactical
These models are designed for self-defense and tactical applications, often featuring shorter barrels, extended magazine tubes, and synthetic stocks.
The Factors Affecting Stock Compatibility
The core of the compatibility issue lies within the design of the receiver, the main body of the shotgun where the bolt and barrel reside. This central component dictates the stock’s attachment points and how it interfaces with the shotgun. There are some key factors you should be aware of before ordering a stock for your shotgun.
Receiver Design
The receiver plays a crucial role. The internal dimensions of the receiver determine how a stock will fit. There are generally two main types of receiver designs that you will see, which impacts stock compatibility. These are the standard and oversized receivers.
Standard receivers have more slender dimensions. Stocks designed for standard receivers are generally compatible with other standard receivers, but might not fit correctly on oversized receivers.
Oversized receivers, typically found in some of the heavier-duty models, have wider internal dimensions. It’s a common source of incompatibility.
This difference in receiver size is a primary cause of headaches for owners trying to swap stocks. It’s critical to know which type your 870 has before purchasing a new stock. Measuring the receiver or comparing it to known models is usually necessary for making this determination, especially if it is not marked on the receiver.
Stock Attachment System
The method by which a stock attaches to the receiver also influences the range of compatible options. There are several different systems in use:
Traditional stocks are typically secured with a single bolt that runs through the pistol grip and threads into the receiver. These stocks generally replace the original stock with a similar design, or use of an adapter to fit a different design.
Pistol Grip Only (PGO) setups are often a choice for tactical builds. These will install a stock which is comprised of only a pistol grip and, typically, a brace, which gives the shooter more control without a shoulder stock. Adaptor plates, or special receivers, can sometimes be necessary to make this configuration work. You want to look at how the grip aligns and the interface point with the receiver.
Picatinny rails are another option. These rails, usually found on tactical models, allow for a variety of stock attachments. This system uses a rail-mounted system for easier attachment.
Gauge of the Shotgun
The gauge of the shotgun can also play a part. While many 870 stocks are interchangeable within the 12-gauge family, stocks for other gauges (like 20-gauge or .410) may have different dimensions or attachment requirements. It is important to be aware of this fact.
Aftermarket Stocks
The aftermarket offers a vast array of stock options, from simple replacements to advanced tactical designs. These aftermarket stocks can further complicate compatibility. Each manufacturer may have their own mounting systems or slight dimensional variations, so it is important to check the specifications for aftermarket stocks.
Model-Specific Information
Knowing your shotgun’s exact model and production date is critical. There are often subtle design differences that influence stock fit, even within the same model family.
Now, let’s discuss how these considerations apply to specific Remington 870 models:
870 Express
The Express models are common. Compatibility is usually straightforward if you confirm the receiver size (standard or oversized). Be mindful of any factory modifications or special features.
870 Wingmaster
Wingmasters may be more likely to have a standard receiver size. Since some Wingmasters use higher-quality wood, many owners want to swap to an upgraded stock, making compatibility a key consideration.
870 Police
The Police models are built for ruggedness. Ensure the replacement stock matches the original attachment style and is designed to withstand the rigors of heavy use. It’s also wise to verify the receiver dimensions.
870 Tactical
Tactical models are often equipped with Picatinny rails. This vastly expands the range of stock options, allowing for a greater degree of customization.
Common Compatibility Issues and Solutions
Issues can still arise even when you’ve done your research.
Loose Fit
A loose fit may indicate an improperly matched stock. Check the attachment bolt and ensure it’s securely tightened. Use shims if necessary to improve the fit.
Tight Fit
A tight fit can indicate that the stock is designed for an oversized receiver. If the stock is extremely difficult to install, stop, and re-evaluate the situation. Forcing it can damage the stock and the receiver.
Alignment Issues
Alignment issues can manifest as canted stocks or difficulty aiming. Carefully inspect the stock’s alignment before tightening the attachment bolt.
Aftermarket Stock Compatibility
Aftermarket stock compatibility is often where the biggest headaches arise. Always review the manufacturer’s instructions and ensure the stock is specifically designed for your 870 model.
Important Safety Considerations
Safety is paramount when working with firearms.
Proper Installation
Always follow the manufacturer’s instructions during installation. Ensure you have the correct tools. Double-check all measurements.
Function Testing
After installing a new stock, function testing is a must. Cycle the action several times to ensure the bolt moves freely and the gun feeds and ejects shells without any problems. Make sure the stock is securely attached and that you can safely operate the shotgun.
Legal Considerations
Familiarize yourself with any legal requirements in your area. Some regions may have restrictions on stock modifications, so it is important to be aware of all applicable laws and regulations before making any changes to your firearm.
Conclusion
So, Are All Remington 870 Stocks Interchangeable?
The answer is a qualified no. Compatibility is not a given; it depends on several factors. Receiver type, model specifics, and the presence of aftermarket modifications all play a role. It’s important to perform your research before buying a new stock.
To reiterate: Before investing in a new stock, carefully research your shotgun’s model, receiver type, and the specific compatibility of the stock you’re considering. Compare measurements, read reviews, and consult with experienced gunsmiths or online forums. When you’re ready to purchase your stock, read the instructions carefully and be sure that all of the steps are clear.
