    I know that some here have had experience with the Knoxx Copstock, but has anyone had any first hand experience with the folding version on an 870?

    870, no. 590, yes. I have one on mine (the folding CopStock, not the new SpecOps stock which looks similar).

    The recoil reduction thing works. Still bangs up your shoulder because it's a big U shaped metal rod for a buttstock, but the spring mechanism really does eat up the kinetic energy. I got used to it, I guess, and fired a friend's 590 almost identical to mine but with the stock... stock. And the bugger hurt.

    So I'm sold on that front.

    My folding mechanism's become a little sloppier than it was when it was new, but it still locks up and isn't going anywhere for any reason other than pinching it to deploy or undeploy. I haven't managed to break it yet, which is more than I can say for other parts on that shotgun.

    On the 590 the pistol grip sort of gets in the way of the forearm release, but the 870 has it in front of the trigger guard so this should be a non-issue.

    Thanks, Zero DgZ. The ad states that you can "one hand" the SG with the folding stock with no problem. I like the handiness of a folding stock SG but I hate shooting it, especially since I tore my rotator cuff.
    Still a bit painful, eh? Have you tried it with any of the reduced recoil rounds?

    No, I only buy cheap stuff.

    One handing it or firing from the hip is actually quite pleasant, as the acceleration involved doesn't whack you with a rubber coated piece of metal. I exaggerate the impact of the wire stock, but it just strikes me as a silly way to go about things. I like mine all the same.

    Word of advice: If you try using your shotgun one handed with the stock folded up like a big pistol you will quickly determine that you are not Ah-nold. That's a lot of weight to be hanging off the end of your outstretched arm and it's got a bunch of leverage! It's fun, but good luck aiming...

    Lord no, I'm not shooting that thing one handed. I just figured that if you could, the recoil couldn't be much. I'm trying to decide between the full length stock and the folder. Preacherman seems to be pretty impressed with the full length stock but if the folder was comparable, I'd go with it.
    Appreciate it...:)

    Can you take the Knoxx Copstock apart? I ask because I'm interested in modifying an 870 as a camp gun. This would be for use in coastal Alaska. But I wouldn't want it unless I could take it apart, clean it thoroughly, and put it back together, just like I can an 870. I e-mailed Knoxx, and they said they did not recommend it. Now, I can disassemble the Butler Creek and Choate folders, no problem. My question is - can you do it with the Knoxx?

    Thanks,

    To an extent.

    The spring area (arguably the place you'd want to clean) is accessed via a little sliding panel on the bottom of the pistol grip. A blast of carb/gun cleaner and then some silicone for rust prevention is all I've ever had to do there.

    The hinge mechanism is retained by some big hex screws. You can remove the stock arm from the hinge by means of a pair of roll pins, which is probably more trouble than it's worth.

    It looks like the spring itself is retained in a couple of places by some drift pins through the whole assembly. I would imagine knocking those out would make things go "sproing" and suddenly become very difficult to reassemble, so I've never tried.

    Thanks. That's good info and pretty much what I expected. I'm still attracted to the Knoxx, but in a marine climate, I like to be able to look over every part if I have to clean it and then put the whole thing back together.

    One complaint I had with the Choate folder is the pad - just a thin bit of rubber bonded to a small metal frame. I'm replacing it with a much larger grind-to-fit pad. I'm doing the same with the Butler Creek and will compare them both. I know how Knoxx is supposed to have much less recoil, but I would have thought they would have put a pad on the thing, just the same.

    The Knoxx SpecOps folding stock is very similar to the CopStock but has a pad on the end of the wire stock.

    No, only the CopStock.

    One last question (maybe:) ); how difficult is installation?

    One screw.

    To get the factory buttstock off, though, you need a pretty damn long screwdriver. My 590 had a slotted hex head thing way down in there, and the recess was too narrow to get a nutsetter into. I had to use my biggest slotted driver and torque the pants off of it. I think the 870 has a similar setup.

    Installing the Knoxx stock is a matter of one big allen head screw, which you install with one big allen key (thoughfully included) and add Loctite to taste.
