Hey folks!
I just bought my 870 12 ga. with a synthetic stock and am currently saving for a mag. extension, a barrel cut-down/ GRS install by GunCat, and some other "upgrades" pertinent to home defense, but in the meantime, I was wondering if you experts had any suggestions on how I could improve the function, action, reliablilty, smoothness, etc. on this thing, armed with nothing but some sanding blocks, files, stones, a dremel and other tool shop doodads.  I know 870s don't REALLY need any help with function or reliability- my youth model 870 that my dad bought me when I was 12 has busted more clays, doves, turkeys, and squirrels than I would care to count without a single malfunction!

Any suggestions, comments, or warnings to lock my workshop with all my tools inside and throw away the key before I do something stupid are greatly appreciated!

Go buy a bunch of 100-round value pack ammo (Fed or Remington - NO WINCHESTER!!) and blast away. The best thing you can do to break in the gun and smoothen up the action is to shoot it.



What extension are you thinking about?



One thing that I recommend is to polish your chamber. Its really easy to do and can be done with what you should have around the house.



- Chuck your shotgun cleaning rod in your power drill and put in a 12ga brush

- Wrap the brush with 0000 steel wool and put some Flitz polish on the brush (I've used chrome polish and got great results)

- Stick the brush in the chamber, turn on the drill, and work it back in forth in the chamber only until its shiny and smooth

- Clean out the bore with some patches and solvent. Run a patch with oil or CLP down the bore when done

Alright- sounds good to me- the more excuses I have to shoot, the better!  I did buy the gun used, so it's pretty smoothed out by now, but it sure can't hurt!  Any reason why Winchester is bad stuff? Dirty/unreliable/ faulty?

I will run by the hardware store and get some steel wool first thing tomorrow!  Can't wait!

Thanks!

keep them coming!

Winchester value pack ammo is known for jamming up guns (most shotguns don't like the stuff, but some will eat it up). The jams aren't hard to work out (place the butt on your thigh and pull down hard on the slide), but are annoying. Speaking of ammo, grab a box or two of the Federal 00 Buck with the flight control wads. Great stuff for HD (still pattern test it JIC).

As Hendricks5150 said, shoot the crap out of it & avoid Winchester Universal shells.

If you really wanted to get the "ultimate" in reliability, I'd skip the extension & add a machined extractor.

Just shoot it.

+100 on the federal with "flight control wad". It will extend your effective range quite a bit. This is really important if you put a shorter barrel with open choke. Check out the Vang Comp safety. it is a big knob on the "safe side" to make it easy to return it to the fire mode with out having to look to see what position it is in. Easy install and worth it.

OP, Id have to suggest you buy a box and try them.  I'm through about 150 without a single failure/malfunction.  It saves me money, and maybe I got lucky that my shotgun likes 'em

Get a Vang-Comp Dome Head Safety. It's probably one of the best things I ever bought for mine other than my Surefire.

In addition to the above.  Some things that could be done.

Deburr and straighten the action bars.
Smooth and polish the outside of the magazine tube.
Deburr, smooth, and polish the inside of the receiver, in and around the action bar slots.
Deburr the ejection port
Deburr, and maybe slightly chamfer the end opening of the magazine tube.
Deburr and radius/chamfer around the loading port.
Smooth and polish the bolt travel area inside the receiver.
Smooth and polish the ejector side of the bolt.
Assemble the gun with fine lapping compound in the working areas, and pump the hell out of it.
Check and deburr the area the where bolt locks into the barrel extension.
Make sure the extractor isn't protruding too far from the bolt and dragging in the receiver.  It makes a hell of a gouge.


As a warning, most of these things would require a complete refinish of the action, would normally be performed by a gunsmith, and probably shouldn't be attempted by someone without the confidence that they can do it right.

Three things will help ensure the weapon is smooth as eel snot.   1.  shoot it  2.  shoot it  3. shoot it more.   There is nothing to to an 870 other then shoot it and rack it hard that can be done to it.  there are not trigger jobs, no polishing and no thing anyone can do to it except shoot the hell out of it.  

Yes, there are some upgrades to enhance feed.   A couple little springs do this.  But since it is new and you just want it smoothed out don't start messing inside it as all you can do is damage.  Becareful what you read on these web sites 'cause you are going to be told some silly mess.  I know these weapon and make a living on them and I am telling you correctly.   If there was anything to do in there then I would be doing it and charging people for it.   Yes, there are some guys out there claiming they can polish this and that and do this and that to a Remington trigger and they are ripping people off.

+1 on the VC safety and the Surefire.

FTEs?  I was kinda figuring it was the ammo. I just finished a rebuilding an 870 but have only used what I had on hand and I've got 4 win vwim value packs, the older packs that I've had for 3 years shot fine but the new stuff was a bitch to extract, I've not found a new gun shop in my new town so I'll have to try it out soon with some better ammo

Yea my 870 and my dad's 870 and Mossberg 590 all wouldn't eat the Winchester crap (even after polishing the chambers I have a few problems). The Federal or Remington is much better.

Where might one get a machined extractor?  Having broken a few extractors on other firearms (not a 870) this is a pet peeve of mine.

Here you go

I've personally never seen a broken MIM extractor, but its still some piece of mind.

They probably scam people by just switching to a 3 lb sear spring. Even then a DIY trigger job isn't that hard; a little sear polishing does wonders to a gritty trigger.

Thanks a bunch for the thoughts, guys!!!

I'll have to grab some caps and blast them this weekend.

Who is "they"?

Just shoot it and shoot it some more.  Save up and get the Surefire fore end.

Get a Remington R3 or limbsaver recoil pad. Your shoulder will thank you after a range trip with lots of slugs and buckshot.

Only thing I can add that hasn't already been mentioned.

Gunsmiths who overcharge on deceptively easy trigger jobs, or any other work that is super easy. I don't have any specific ones, but I'm sure someone had been "had" by an unethical gunsmith.
