Remington 870 express tactical stock issue...

[9unknown]

Picked up a Remington 870 express about a month or two ago, great shotgun, it's the one with the knoxx specops adjustable stock. Up until this past weekend I hadn't any problems with it, cycles great, probably put over 200 rounds through it no problem (mainly slugs), until the stock and grip suddenly jerked forward after firing a round. I looked down to see that somehow the stock and grip had lunged forward over the trigger. It's now loose and sliding back and forth about 1/2 inch, not cool(see attached pics).





At first i thought maybe it was the hex head bolt that secures it to the receiver but on further inspection found that it was nice and tight like it should be. I took it back to my FFL dealer since i didn't have the tool specific to the knoxx stock, and they said they'd never seen anything like it before, was just wondering if anyone here might have any insight before i ship it back to Remington...

It will have to go back to Remington. There is a spring down in the pistol grip and it has jumped off the pin the in the reciever mount. You can not repair it as it is a factory repair only. Remington will send it back to Black Hawk. Remington Will send you another one since the weapon is under warrenty. I have returned three to Black Hawk for the same reason. Never happened when Knoxx made the stock but is becomming a problem since Black Hawk bought them out and moved the factory. This is the only thing you can do.......

From the way it looks, I'm guessing this is a stock failure or stock installation failure. I don't think there is anything wrong with the gun itself. +1 on never seeing anything like this before. Looks like whatever was retaining the spring/buffer of the stock is not doing it anymore. Something slipped out of spec.

You sure you want to send it back to Remington? You might be without the gun for a few months. If anyone else has sent something back to Remington, hopefully they can post here with their experiences, but I imagine waiting times are up there. Might save you trouble just to replace the stock.

Yeh, spring failure seems to be the consensus. According to my local FFL they have a repair shop relatively close so wait time shouldn't be too bad, but still a major pain as I'll have to remove some parts before I ship.

Aippi, if you've replaced three of these that really does concern me as this gun is mainly for HD purposes. Not sure i want to potentially put my life in the hands of a weapon system that takes a **** whenever it decides to.
Maybe a different stock is a better resolution, I've been eyeing up that mesa stock kit with the hydraulic recoil buffer. so pricey though...

+1 for that being a new one on me as well.

Assuming you purchased new and the gun came from the factory with the stock, look here for Remington Authorized Warranty repairs. There are three in SoCal.

I am a Remington Dealer, I was a Knoxx Dealer before the sale. I gave you the only option you have. You don't have to send the weapon just the stock, or call Black Hawk and they may take it back as they are aware of the issue . I just replaced another one on customers weapon, same guy, two failures. This makes me think that if Black Hawk changed the spring and there is a shooter issue this is the cause. If you don't allow the stock to cam all the way back and you fight it, this could be the cause. The left arm has to be loose, almost as if the forend was just resting in your palm. This allows the weapon to cam back and return. If you lock your left arm you freeze up the weapon and this could be causeing the failure. As for three coming back, well there is another over 400 that have not and since I warrenty my custom builds for two years and stand by any accessories I seel, well, I would have heard if other failed. Three out 400 is not a serious issue if it is a manufactures defect. Black Hawk moved the factory so it was all new employees and the stocks I had fail might have just been because the people building them were new. I say get the new one form Remington and use Again, this is the only option you have as you can't send it to a Remington repair shop as they can not repair the stock. They don't make that stock, Black Hawk does.

You're right, 3-4 out of 400 isn't bad at all. I'll see about just contacting Blackhawk and returning the stock, though I doubt the malfunction was from operator error, always a possibility.

Thanks for all the info everyone.

[aippi]

Oh no, not operator error alone. Shooting it improperly could contribute but the main issue is cam spring in the pistol grip. If you go to www.blackhawk.com and click on stocks then SpecOps there is a cut away drawing. You will see how the cam spring conected to a rod throug the receiver mount. that spring is jumping off. If the stock is being locked up while trying to cam back then the hook in the spring would raise up and can jump off the pin. So with a combination of design and operator error the malfunction occures. Black can correct this simply by making the hook at the end of the spring longer or even and eye instead of a hook. This ends the issue.......

I like the SpecOps stock. I hope BlackHawk sees this suggestion and improves its future SpecOps production.

Embrace the KISS principle and you won't have this problem.

But your going to feel more recoil.

agreed, Other than this one issue the stock has been great, though i do see the benefits of a more simplistic setup.

Recommend you send just the stock back to whomever you deem most appropriate.

In the mean time, if it takes too long to get a replacement, you can always pick up a Hogue or something similar as a temp. They don't go for much. Who knows, you might like it more than the Spec-Ops. I personally prefer a standard hard stock to any setup.

Good call, best to have a nice reliable stock around that may not be fancy but will always get the job done. However, I'm still very curious about that mesa tactical with the enidine hydraulic buffer.
