Remington 870 Parts List

List of the Remington 870 parts and schematics. Searching for different parts may be problematic, so I decided to make this table and list all the Remington 870’s parts. I have linked them to Brownells where you can get them at a good price with fast delivery. I have ordered all my parts from them for years and have always been more than satisfied.

Look at the schematics, search for the Remington 870 part that you need in the table and then click on the link to order it. Please note that most of the parts are available but some may be out of stock. You should contact Remington directly to order the shotgun parts that you need which are out of stock.
Anyway, I recommend having a set of spare parts with you. It doesn’t take much space in your range bag or backpack but it may save the day if you have some minor breakage.

Some of the parts that I highly recommend that you have are the non-MIM extractor, different springs, ejector, ejector spring, firing pin, firing pin spring, shell latches, and different pins. Those parts are inexpensive but very important to have.

It is always good to have a basic repair kit at home and in a range bag. The repair kit is a must have when you travel somewhere to hunt or shoot. It would be very disappointing to drive hundreds of miles to find out that some two-dollar part broke and you can no longer use your shotgun. A minor repair procedure with the proper tools will take just several minutes.

So, always have spare parts in your repair kit. And also, don’t forget about tools.
You don’t need to get all the parts from the list. Just make sure that you have the ones that are most prone to failure.

You will find instructions on how to fix many of the Remington 870 problems in the How-to Videos Section. The Remington 870 parts that are most likely to fail are the:
-Ejector
-Ejector Spring
-MIM Extractor
-Springs
-Firing Pin
-Firing Pin Spring
-Shell Latches
-Pins
-Magazine spring
-Factory follower

You can even buy a complete metal trigger group in case something happens to your shotgun. That way, you can just swap a trigger group and repair the broken one later. The same thing can be done with the bolt.

Spare Parts Every Shotgun Owner Should Have On Hand

Anything mechanical will break down at some point and it is usually at the worst of times. Your weeklong hunting trip can be ruined the first day if you do not have the extra parts needed and a few basic tools to make field repairs to your shotgun.

Remington 870 Repair Kit

Anything on your shotgun can be replaced but like a motor vehicle it may get to the point where buying a new one makes more economical sense. However, springs and firing pins can be changed out in a matter of minutes as well as the barrel, and the parts and tools are easily carried wherever you travel with your shotgun.

Remington 870 Field Repair Kit:

Remington 870 Repair Kit

You can get Remington 870 Repair Kit on Brownells

A Remington 870 filed repair kit containing a firing pin, firing pin spring, retaining pin, an extractor for a 12,16 and 20 gauge , a plunger, spring for the extractor, spring retainer for a magazine in the old style and one in the new style along with front and rear triggers detent springs.

You should also carry an extra forend; they are relatively inexpensive and can be easily changed out by typically removing the barrel. You will need a flat tipped screwdriver to remove the barrel and there is a special tool for removing the forend on a Remington 870 but you can use pliers to unscrew the cap to remove it from the slide tube.

Examine your particular weapon to make sure the forend is not riveted to the slide tube, which means it is a one-piece and you would have to purchase an after market slide tube to attach a new forend. Carry an extra bolt as well, and practice changing it out in the field.

Some of you may have several barrels one smooth bore and one rifled; the rifled barrels use particular ammunition and most experts will tell you that firing steel shot and even lead shot through the barrel will wear the rifling off. Have a smoothbore barrel as a back up because they can fire any type ammunition. If you ruin your rifled barrel because of overheating or some other mishap with the weapon, you must be able to change out the barrel. If you find yourself with only steel shot, you would also want to change out the barrel for a smoothbore.

Some of you may not consider a sling as a spare part but a sling is vital in some situations, and you should always have a backup one. Some may not use a sling when hunting or in a tactical situation but you should have one available. You must be able to sling the weapon if you use a tree stand or have to get into a tree for any reason or you must climb a hillside. There will be times when you cannot set your weapon down and yet you still need two hands so a sling is a vital spare part.

You can purchase drop in trigger kits that can be replaced in the field.
