Why Remington 870 is the best pump action shotgun? Because there are hundreds of upgrades available for it! You can customize it as you wish and even make it a bullpup shotgun! :) But let’s talk about more common Remington 870 upgrades today.

I have made updated list of must have upgrades for Remignton 870. This time I have selected the best (in my opinion) upgrade in each category but also offer you several alternative variants and links to reviews.

So, let’s start with the most important upgrade for any home defense or tactical Remignton 870…

1. Flashlight

Light on a is one of the most important upgrades that are required for a home-defense or tactical shotgun. Adding a tactical flashlight to a shotgun – is one of the first advices that all firearm instructors give. If you have flashlight on your shotgun you can use it day and night. If you can’t identify target, you can’t shoot it. I recommend choosing the CDM Gear Clamp + Streamlight TLR-1 (or TLR-2)

CDM Gear Clamp is one of the best ways to attach a flashlight to your Remington 870 shotgun. It is lightweight and easy to install. The CDM Gear clamp and flahslight combo is affordable and high-quality upgrade for any tactical or homedefense shotgun.

CDM Gear clamp is lightweight, low profile and compact. Streamlight TLR-1 is high-quality, powerful and virtually indestructible flashlight which is easily attached to a CDM Gear Clamp’s rail. TLR-1 is low profile and doesn’t stick out much.

Streamlight made a very wise decision and offers Streamlight TLR-1 Tactical Flashlight with CDM Gear BMT Shotgun Mount kits.

P.S.: Streamlight TLR-1 can be installed on Magpul Forend using Magpul Remignton 870 MOE Scout Mount.

2. Stock

There are lots of aftermarket stocks available for Remington 870. It was a difficult decision to make but I decided that the best stock is Magpul SGA stock for Remington 870. It gives you so many advantages and it is so easy to customize!

You can adjust length of pull, add cheekriser, sling attachment plate, etc. Magpul SGA stock for Remignton 870 is rock-solid, reliable and very popular among shooters.

The stock that fits you is very important because it enables you to hold it properly and shoot more comfortable.

4. Magazine Extension

Standard Remington 870 shotgun has just 4+1 rounds. That is why one of the first purchases of many shotgun owners is magazine extension. That is very wise decision because shotgun has very limited number of roynds. Extension enables you to have 7+1 rounds which is almost two times more.

Original Remington 870 extension is the most reliable and sturdy extension you can find:

5. Oversized Safety Button

Factory safety button on Remington 870 is too small. Oversized safety button enables you to quickly disengage it in stress or home defense situation. Also, it would be much more easier to find oversized safety when wearing gloves.

Installation of the oversized safety button is easy and fast.

Vang Comp Systems was the first oversized safety for Remington 870 shotguns. It is one of the most popular aftermarket safeties.

6. Enhanced Follower

Changing factory magazine follower is extremely important to ensure reliable feeding. Remember, that broken extractor can stuck inside the magazine tube and you will have to disassemble your shotgun to fix that. And if we are talking about self-defense situation this is the worst case scenario.

Factory follower is junk, remove it as soon as possible!

Vang Comp Systems (VCS) Follower

Vang Comp Systems is made of stainless steel magazine follower. This is one of the best followers I have ever used. It is sturdy, reliable and virtually indestructible.

7. Better Sights

Better sights are very important because you use them every time you shoot. It is good idea go get Tritium sights because they glow in the dark for years.

9. Sidesaddle

These sidesaddles are well known and very convenient to carry additional ammunition on your shotgun. As you know, shotguns have very limited number of rounds, that is why sidesaddles are so popular, they enable you to have additional 4, 6 or even 8 rounds on your shotgun.

10. Shorter barrel

The most popular barrel for homedefense is the Remington 870 18″ bead sight barrel. It is short, simple and inexpensive.

This short barrel enables you to easily manouevre around the house. It is possible to change the factory bead with light gathering or Tritium one.

This barrel is universal tool which is good for almost any purpose. Of course, longer barrel will be better for hunting and ghost ring sights will be better for home defense. But 18″ bead sight barrel enables you to do almost all tasks. It is good choice for beginners or for people that want to have only one shotgun for home defense and for week end clay shooting.

Barrel which is shorter than 18″ usually requires special license.
