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.

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.

Tritium sights basically provide green or yellow sight lights on your shotgun that glow in the dark. They have been nicknamed “night sights” for this reason and get installed on the rear or front of your shotgun. Tritium is described as a radioactive isotope of hydrogen. The sights use tiny vials of tritium that are responsible for emitting its soft green glow. If you are in an area with low lighting or darkness then the tritium sights will allow you to see where you’re aiming.

You may be faced at some point with multiple targets, multiple targets that are shooting back at you. Most firing ranges are set up so you only focus on one target at a time unless it is a specialized training facility. You fire, the buzzer goes off and you bench your weapon, it is synchronized to some extent, firefights are not. Therefore, most shooters focus on becoming proficient while shooting at one target in a controlled environment.
I’ve heard about this Remington 870 modification several times. I was not sure about it because it requires modification of the ejection window and it cannot be undone. This is the most radical way to improve reliability of your Remington 870, so if you don’t have many issues with extraction you don’t need it.
