Jewel trigger adjustment

[GaryinIllinois]

Can anyone point me to instructions for adjusting a Jewel trigger on a Cooper rifle? I looked at the Jewel trigger adjustment instructions posted on this sight but found that the Jewel trigger on the Cooper rifle is quite different from the ones shown in the posted instructions (it has several more adjustment screws).

Thanks for any help.

Which model Cooper?

Jewel for a Cooper? Are you sure it's not a Jard? Not doubting you but I don't remember seeing a Jewell for a Cooper.

My model 54 had a heck of a stiff spring in the factory trigger.

Can you post a picture showing all the trigger adjusting screws?

There aren’t too many of them but it is, in fact, a factory Jewell on a Cooper model 21. I’ll try to post a photo.

Sweet! After I posted, I googled it and found that Jewell did in fact make those for a while. I've just never seen one. You have a desirable trigger there, based on what others said in that regard. It sure looks like a Jewell. Sorry, can't be much help with instructions but I wouldn't be afraid to start adjusting on it, myself.

The rifle was bought used and has been used on a couple of prairie dog shoots. In getting ready to go this year we discovered that the striker assembly is now following the bolt home when closed most of the time. I am unsure how to adjust.

Any help is appreciated .

Try flushing it with lighter fluid, May just be some crud in there, Or it could be that things have worn slightly over time and the trigger was set on the very edge to start out with.

Considering that the shoe is snapped in half, it may have some internal damage as well.

I flushed the trigger with lighter fluid with no improvement. The bottom of the trigger blade has been shortened by the previous owner and a wide trigger shoe installed (not sure why this was done) but the trigger has functioned properly for the last several years this way. The trigger pull weight is very light (only several ounces) but has been reliable up until now.

One would assume the front screw being backed out as much as it is would be the pull weight.

I've had a couple jewels with broken trigger blades. They got bumped when out of the stock and break really easily. Fortunately when the last one happened they were still taking repairs but didn't have complete triggers anymore.

That looks just about as annoying to keep adjusted as my Jewell AR15 trigger, lol! It has only 4 adjustments but they have to be done in a specific order.

A friend who collects older Coopers had a copy of the Cooper - Jewell schematics with adjustment instructions and sent them to me. Now, if I can just follow the instructions to get the trigger back in operation.

Thanks,
