There is one issue which you can experience with Remington 870. It is called “sticky chamber or a “rough chamber”. It happens often with cheap ammo. And you need to polish the chamber to be able to use any ammo you want. I have posted instructions on how to polish the Remington 870 chamber some time ago, but now I want to give you 3 more ways to polish the 870 chamber.
Here is how-to article from Banshee from Remington 870 Forum.
Hogue short LOP stock was too short for me for competition use (but great for home defense) and standard stock was a little too long. So I decided to remvoe half of inch for a perfect fit. Watch the video.

You can get more reliability out of your Remington 870 shotgun if you upgrade its carrier dog spring, or sometimes called the carrier latch spring. Sometimes you will find that your shotgun has feeding problems which will make it unreliable when shooting it. But if you were to use a heavier carrier dog spring then it will fix these feeding problems and improve the gun’s reliability at the same time. The spring does this by lifting the next round of ammunition after it comes out of the magazine tube. If the rounds don’t get lifted properly then you won’t be able to keep shooting your weapon. This could put you at risk if you’re in a situation where you need to defend yourself. That is why Remington 870 Police shotguns are the most reliable because they use the best carrier dog springs. If you want to put one of these springs in your Remington 870 then you can get it from model 1100, part number F16966. This is the exact carrier dog spring used in the police version of the Remington 870, but the spring is also compatible with other Remington 870 versions.
The Remington 870 shotgun has three types of sear springs including the standard, competition, and police. The standard sear spring gives a trigger pull of between 4 to 5 pounds. You will find this spring inside all Remington 870 Express shotguns. If you just use your shotgun occasionally for hunting or home protection then the standard should be fine. But if you are a competitive shooter or want to shoot fast then the competition sear spring will provide a much lighter pull at about 3 pounds. As for the police sear spring, it is a heavy duty sear spring with a trigger pull of up to 8 pounds. This is the safest and most reliable trigger pull because of all the effort needed to pull the trigger.
When you fire a Remington 870, or any other type of shotgun, you will see the shells fall out of the chamber onto the ground. The part of the shotgun that removes shell after it is fired is called the extractor. Once you cycle the action of the gun, the shell is removed from the firing chamber. It is important to have a durable extractor if you use your shotgun a lot. Most Remington 870 shotgun models come with a metal injection molded extractor which is good for standard use only. But if you are someone who goes shooting a lot then you will want a solid steel extractor in your shotgun instead. These extractors are typically found in Remington 870 Police models since law enforcement officials tend to shoot shotguns more often than civilians. However, this doesn’t mean you can’t install a solid steel extractor into your Remington 870 to make it more reliable.
When you want to replace the safety button of your Remington 870 you will want to install an oversized safety button. This will allow you to disengage the button more easily, especially if you are wearing gloves or are in a stressful situation where you may lack focus and concentration.
The first thing you want to do when trying to replace the forend of your Remington 870 is to make sure the weapon is unloaded. You’ll want to check both the chamber and magazine tube by visually looking at them and by feeling around with your fingers. That way you can ensure that you don’t have any accidents during the process of replacing your forend. Next, you will need to gather the right tool for doing this job. There is a special forend removal tool that you can purchase at most gun stores, but if you have a pair of pliers then they will be fine.
