Is The Remington 870 a Good Gun to Customize?

The Remington 870 is well suited for customizing, due to the ease of finding parts of every description for this popular gun. It has been around for almost 70 years, so parts manufacturers are well aware of how to make the gun more effective and fun.

In addition, the accessories out there will allow you to create the perfect tactical home defense or hunting weapon, as well as a trick it out for competitive shooting.

However, it is not built on a modular platform, such as the AR platform. This means that swapping out parts is definitely doable, but keep in mind that not everything can be upgraded on your own using your own workbench. There are some modifications that will need a professional gunsmith.

​​​​Which Accessories Are Best For Home Defense?  


Slings will create comfort when carrying a heavy gun and at the same time will prevent others from taking them away from you in a fight.

They're are also the easiest way to carry a gun around when you’re out in a hunt or shooting. slings come in various types, depending on the number of attachment points to the gun, e.g. a one-point, two-point, and three-point sling.

Magazine Extension

One downside of shotguns is they don’t hold very many shells at one time. Fortunately, you can buy a Remington 870 magazine extension upgrade to improve the shell capacity of your shotgun or the majority of the other firearms you might have. 

You would add a tubular magazine extension to the magazine tube of your weapon. Therefore, you will be able to fire more than normal, before having to manually reload your weapon.

It's worth paying for it only if you use your weapon with frequency and have a reason to fire a lot of ammunition in a short time. Police and military officers, for example, may find Remington 870 magazine extensions to be worth buying.


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

Recoil Pads

Every Remington 870 comes with factory fitted recoil pads. A recoil pad is a piece of soft material such as rubber, foam, leather, etc. that is attached to the buttstock of a rifle or shotgun.

It is meant to provide additional padding between the hard buttstock surface and the shooter’s shoulder. This prevents the pain and discomfort associated with the recoil from the gun.

In addition, it prevents the gun from slipping on the shooter’s clothing and helps the shooter not to foul up the second shot.

Why You Should Upgrade Your Remington 870  

You may be asking yourself why you should upgrade a shotgun that is already working perfectly fine. The answer being you have access to a variety of parts that can enhance accuracy.

Every factory Remington 870 is identical, but each shooter has different physiques, shooting styles and techniques.

In order to make your gun suit your exacting requirements, you should customize the gun to fit comfortably, improving accuracy and easy to carry around. After all, the gun should make your life convenient and not the other way around.

A customized shotgun can aid you in your professional and recreational shooting, both for hunting and home defense purposes.
