Buyer's Guide

The 870 magazine extension significantly enhances your semi-automatic 870 shotgun's capacity and functionality. This guide outlines key features and considerations to help you select the right extension for your shooting needs.

Magazine Compatibility and Fit

The extension must match your shotgun's make and model precisely. Read specifications carefully to ensure compatibility with your barrel length and magazine configuration. Misfitting extensions can affect gun handling and reliability.

Capacity and Magazine Design

Standard 870 extensions increase capacity from 5 to 8 shells. Some premium extensions offer up to 10-round capacity. Consider your shooting style – competition or hunting – to determine ideal capacity. Modern designs prioritize ergonomics and quick reload capability.

Maintenance and Durability

Look for extensions made from robust materials like stainless steel or high-carbon steel for longevity. Proper maintenance includes regular inspection for cracks or damage, and cleaning after each use to prevent corrosion.

Additional Features

Some extensions feature enhanced gripping surfaces, dust covers, or extended ejection ports. These additional features can improve handling and functionality, but may slightly increase recoil. Evaluate whether these benefits outweigh potential drawbacks for your shooting style.

FAQ

What is an 870 Magazine Extension?

The 870 Magazine Extension is a tube-shaped accessory that extends the magazine capacity of Remington 870 shotguns. The original 870 holds 5 rounds in its magazine, while the extension allows for an additional 3 rounds, bringing the total capacity to 8 rounds per magazine.

These extensions are available in two main types: drop-in and underbarrel. Drop-in extensions clip directly onto the magazine, while underbarrel extensions attach beneath the firearm's receiver.

What Calibers Work with the 870 Magazine Extension?

The 870 Magazine Extension is compatible with multiple calibers, including 20-gauge, 28-gauge, 32-gauge, 320, and 410-bore. The specific caliber is determined by the shotgun barrel and magazine design.

It's important to verify compatibility with your firearm's barrel length and magazine configuration before purchasing an extension.

How Do I Install the Magazine Extension?

Installation varies between drop-in and underbarrel extensions. Drop-in extensions typically clip directly onto the magazine using finger tabs, requiring no tools. Underbarrel extensions attach beneath the receiver using screws and special magazine adapters.

Always refer to the manufacturer's instructions for proper installation to ensure safe and reliable function.

Can I Use Both Underbarrel and Drop-In Extensions Together?

Some 870 models support dual magazine systems, allowing both underbarrel and drop-in extensions. However, compatibility depends on your specific firearm model and configuration.

If you're using a dual-system setup, consult your owner's manual or manufacturer guidelines to ensure safe operation.

What Are the Benefits of Using a Magazine Extension?

Magazine extensions increase ammunition capacity, providing faster reloads and more sustained fire. They're particularly useful for hunting, home defense, and competitive shooting where higher magazine counts are advantageous.

These extensions also help maintain proper balance and reduce muzzle rise, making your shots more consistent.

Are There Any Disadvantages to Using a Magazine Extension?

Magazine extensions add weight to your shotgun, which may affect balance and handling. Some users report increased felt recoil when using extended magazines.

Extended capacity magazines are generally more expensive than standard magazines, and compatibility can vary between firearm models.
