I made a stop at one of my favorite gun shops today and found a Remington 870 Competition. I really did not know what it was until I got it home, but have since found it has the gas operated recoil reduction piston built into the magazine. I am excited to get this one to the range to see how it performs.

From what I have read so far on the internet, they (Remington)no longer make any parts for this model. Is there a part or parts that are common or prone to fail on these...? If the gas system fails can the gun still be used without that feature..? Are there any aftermarket parts available for this that I have not found in my search..? Thank you for your input.

Not too many parts available. Cautionary things to watch: keep the end cap screwed down and keep your loads trap speed. The receivers have been known to crack just past the ejection port and the fore mentioned items are the consensus of some owners.(personal experience showed that mine still cracked irregardless of following consensus) If it does crack, drill a 3/16" to 1/4" hole at the end of the line. Gun will still function fine. A great patterning gun possibly due to the factory increased bore diameter. Some of the magazine tube (recoil system) parts could be made by a competent gunsmith if ever needed. You'll enjoy shooting it! mb

Cliff: I'm hoping it has NOT been molested. Be sure to clean it very well 1st, remove the piston by depressing the small retaining pin and clean the gas ports carefully they are very similar to an 1100, they are small if you don't have wire size drill bits a small straightened out paper clip is about the correct size. Remove the magazine spring and clean it and the inside of the tube also, as this is where the piston travels.

If you shoot light 7\8oz loads you may not notice the recoil system working "but it is", if you shoot a 3DE 1200 FPS load you will "feel" the system working. They are a wonderful gun, never could figure out why Rem. discontinued them. Your going to love it. Ross Puls

There are parts available, but not all of them.

Numrichs, if I spelled it correctly, has a few.

I check there every month or so and buy any nos part I can If it is an alright price.

Viton makes a decent o ring for the barrell seal, >017 or .018 i can't remember which one off hand. I bought a bag of fifty each to try them out.

Purchase a new spring.

The magazine cap should be tightened between each station just to be safe.

The wood is nice and it is not pressed checkering.

The model of the competition is an 870CT when you look for parts.

Thanks for the replies. I disassembled the gun and cleaned it. It was pretty obvious that the previous owner had not seen the internal parts of the gun for some time. I ordered an O-ring from Midway yesterday. I'll have to go searching for the spring now.

Cliff,

Try Numerich for the piston return spring. I may be wrong but the p/n shown is 822390 @ $12.90. I bought a comp awhile back and like you, the previous owner was negligent on his cleaning. I had a heck of a time trying to remove the the spring and buffer from the mag tube. Once I removed it, I clean the tube after each time it has been shot. No chance for it to fill with crud.

Thanks for the tip, I'll check that out right away. Hopefully it will be warm enough to try this one out this weekend, then I can clean it up again and install the new ring and spring.
