Hello gents, I've got my dad's old 840 single shot 12ga.

The foregrip is loose- very loose. The little spring clip seems to work just fine, but maybe the wood has been compressed over the years?

My dad told me he used to just wrap a strap around it.

I'd like to fix it. Any ideas?



And some pics for flavour.

In what manner is it loose?does it rock side to side ,movement forward and rearward or does it have slap up and down against the barrel?did you check to see that the iron is tight in the forearm?

the forward end slaps up and down. It acts like the little spring arm isn't long enough to put a good squeeze on. And yes, I checked the iron. Tight as a drum!
 
Looking at your pics it looks like the spacer on the back of the forearm is not the orginial as it does not fit the contour of the reciever.this could possibley be the cause of the looseness.
 
Are the screws tight. All 4?

I have one that the screws would always back out. Semi-stripped, and over oiled.

To fix it I drilled out the screw holes to 1/4" and then glued in 1/4" hardwood dowelling. After that I re-drilled the wood (pilot hole) and then put the screws back in. Careful not to drill right through.
*Important note. If I had to do it again, I would do it one hole at a time, as it was really hard to get everything lined up to drill new holes with everything apart. Mine came out a little crooked, but it's tight now and the screws haven't moved since.

I don't know... you may be right.

I'll re-examine these screws and spacers.

If it's just a matter of shimming the spacer out it should be no problem. I can get some very very thin shim steel and and fix it up :)

Thanks for the wood dowel tip.

I'll post back when I have results
 
I have to admit - My Cooey is doing exactly the same thing; and all I did was wrap electrical tape around it' the gun already has a band of electrical tape holding a shoulder strap to the barrel. Wouldnt mind knowing how to fix this right however.
 
The simplest solution might be to put a shim between the spring and it's base. This would increase the spring tension against the forend, you'll have to experiment with how much, but I'd start by adding the equivalent of a full coil to the spring. I though that perhaps moving the entire hardware assembly ahead might work, but the engagement flange of the forend assembly to the receiver prevents this, and there appears to be no easy way to replace the spring.
 
I don't know what kind of spring you would call this - it's a sort of curved blade with what appears to be a tiny coil spring under it. I've never seen any other cooeys to reference :)

You can see here where the blade starts to contact the barrel. It is about 1/4" back of the locking point with the spacer snugged up to the trigger stock. I think this should be closer to put more tension on it? Neither the blade nor the barrel appear to be worn.

Some of the screws are not the tightest. However, all parts are secure. Nothing rattles. Maybe the metal spacer is a replacement part that just isn't up to snuff? To my eye it LOOKS like I could space it out a bit and tighten up the stock?

Also as an aside I took this baby out to blast some targets.. what an eye opener. This thing kicks harder than anything I've EVER fired before!
 
It appears you have an 84 forend on an 840 gun. The 840 forend uses a coil spring wrapped around a pin that has a bevelled end which mates to the forend hanger on the barrel.
 
Do you have a picture of what you're talking about?

I find it slightly hard to believe it's the wrong forend since I believe my dad bought this gun new. But, he was never much for mechanical inclination. So who knows.

[edit]

so - I did some google searching.

This is what's on the forend -

and everywhere I looked it's listed as for a winchester 370

and this is what I need -

So you were absolutely correct, thank you very much for the advice.

Looks like they're cheap and available too. Perfect!
