Rem. 870 Stock help

I purchased a Remington 870 with the synthetic furniture this summer. I've been experimenting with folding stocks, etc, and while the Knoxx Copstock is a decent folder, I'd like to go back to the standard stock. Particuarly since I am about to get a full-size truck, with the room to actually store a full-stocked 870...

Anyway, the synthetic stock that came with the 870 is kind of cheesy. It is hollow, and the factory recoil pad isn't great. Only the rim of the stock is in actual contact with the pad, so a lot of surface area is not being utilized in recoil reduction.

I'd like to fill the hollow cavity with some kind of resin material (I'd protect the bolt channel, of course) to give the recoil pad more area to mount against. I'm also going to put a better recoil pad (like a nice Limbsaver) on it.

Any advice? I'd like to be able to get what I need at my local Autozone or Lowe's...

Jack West makes the best synthetic stocks for 1100s and 870s that I've run into. While it looks like overkill with the adjustable comb at first, being able to make a field gun fit this well does very good things for your field shooting.

If you order a Knoxx stock beware that you will need a number of tools to install it like Sockets, ball end screw driver ect. I wasn't paying attention and just figured this out with the Specops stock

I've already got the Knoxx Copstock installed (and it works fine) but I'd like to go back to the regular stock...

And I'm not spending $250 bucks on a new stock. Let me repeat...

I'd like to fill the hollow cavity with some kind of resin material (I'd protect the bolt channel, of course) to give the recoil pad more area to mount against. I'm also going to put a better recoil pad (like a nice Limbsaver) on it.

I'm thinking like $20 and less. And buying the materials locally, not ordering them off of the internet or spending a whole lot of money.

I should also mention that I do like the stock itself because my gunsmith cut the forearm down and did custom stippling on both the buttstock pistol grip area and the forearm for a better grip.

You could fill it with casting resin. Just make sure you use some fiber glass filling to reinforce it or it will fracture very quickly.

Anything exothermic might warp the stock... be careful.

Foam in a can--the stuff you use to fill cracks and insulate holes. Just use a piece of PVC or other tubing to protect the bolt hole and then fill'er up. It will add rigidity and sound deading. Just don't overfill, it's a little tough to clean up once it dries.

How about a Speedfeed II solid stock?

I cant remember, its been a while since Ive had my synthetic stock, but isnt there a rigid plastic spacer attached to the recoil pad that goes between the pad and the stock?
If I am remembering correctly, then it doesnt really matter that the stock only touches it at the edges.
I would buy the limbsaver replacement recoil and be done with it. Or better yet, get a wood stock.
What do you do with the gun?

Mine didn't come with the spacer. Might be because my smith had taken it off when he removed the stock to stiple it. Or might be because there was never one in the first place.

I've ordered a replacement limbsaver, but do want to go ahead and utilize that empty space. Yesterday, I packed the space with rolls of pennies (One whole roll, and two half-rolls), with some folded paper. This gives me some good weight w/o making the gun seem too heavy.

Once I put on the new Limbsaver, that should finish it out.

BTW, this is my HD gun.

Get a good used Wood Stock, and have this stock tweaked to fit you.
Pachmayer Decelerator, installed while the gun fitting is being done.

Sell the other stuff and enjoy a well fitting gun and become one with the gun.

WARNING WARNING WARNING!!!!

I wanted to make my rem870 look cool/shorter, so I bought a knoxx recoil reducing copstock....the thing has a huge spring/cam system in the handle that kills the recoil well...1.5oz turkey 3.5inch shells didn't hurt a bit. However...the whole gun recoils back relative to the pistol grip...and recoils HARD. I was hit hard in the mouth...bleed like a pig had to get 6 stitches in the lip and had a huge chunk taken out of my gum above my right k-9 tooth.


Just be aware that this stock can bite you hard in the face. You need to keep your face at least 2 inches back from the end of the stock and be sure to tell others whom shoot your gun about it.

I'm very well aware of this. Not that I can shoot 3.5" shells in my shotgun...
I've already removed the Knoxx Copstock, which while it fit my needs, I just wanted to go back to the solid stock.

I got a nice set of wood furniture (old stock police wood I guess) off of ebay for about $40. I think it is identical to the synthetic stocks that came on my 870 POLICE. I like but for one thing...the grip is not vertical enough to get a good trigger pull. It seems that at that angle, the natural motion for the trigger finger is more "up" than "back" (which is the direction of the trigger, obviously). I might try to do some sanding and reshaping to make it more natural for me.

The other option I saw the the Hogue Overmolded Shotgun stocks....does anybody have any experience with those? They look like the grip is a little more vertical than the original stock.

I wonder what he ever did do. I spray rigid expanding foam in my stocks that I don't like hollow as a cheap solution. You can then trim to fit and replace the end.

Sticking to the question you asked: you should be able to use either the foam insulation or one of Brownells' glass bedding compounds--possibly Acra-Glass?

Information you can use for the latter approach is in a Brownells' tech note on do-it-yourself customization of a Glock grip. Yes, I know it sounds irrelevant but it isn't. All you'd want from that note is the name of the product and how to use it for your purpose. Or you could phone Brownells' tech support guys and ask what they'd recommend and how they recommend you do it.

My guess is that the bedding compound would add more substance and probably more weight to the stock than the foam insulation. If you go with the foam insulation, look for one of the newer products that is relatively slow to set and that cleans up with water. Then squirt it into the stock in layers of about 1-2 inches, allowing each layer to expand, dry, and cure a bit before you add the next layer. That way of proceeding will take more time than a quick big squirt but it should give you a better result.

It's not a whacky idea, by the way.

readyme, I have a Hogue overmolded stock on my 870. It's a well designed stock and is very easy to hold on to with the tacky rubber covering. It has a very effective recoil pad. They have a slightly long length of pull. I am average sized guy and I wish it was just a little shorter but I don't think it can be cut down because of the internal construction. You might get away with a thinner pad if you can tolerate recoil well. Overall I like it.

Well, I'm in between solutions right now. Gun has original synthetic stock on it, with a Limbsaver recoil pad (and it still recoils too hard for me, and doesn't fit very well, but it is shootable- I'm working on that.). I bought a Speedfeed II solid stock, too. It shipped with the wrong recoil pad. I'm trying to find a smith to grind to fit a Limbsaver on it, and help me with shotgun fit. No one knows anything about that around here, and the gun store owners don't care to help me. No one is willing to do grind to fit pads, either.

I don't tolerate recoil well, and I'm considering options to take care of this. I'm either going to order one of the Knoxx Spec. Ops stocks w/ the M4 style stock or get a Remington 1100 to soften recoil. I still want to stick with 12 gauge desperately because of the wide availability of loads (20 guage buck and slugs are nigh unavailable in this area).

If anyone knows of a recoil pad that will go on the Speedfeed stock w/o modification (try to stick w/ Limbsaver, as it is the most available around here) I would be most grateful.
