I want to adjust the trigger on my MRC1999 but they say the don't have any instructions on how to do it, probably a liability worry. They did say it's the same as a Winchester M70, anyone have knowledge of a website that gives specifics with diagrams or pics?


Thanks, Rob

It takes only two (I believe 8MM) wrenches and a small screwdriver. Just look at the setup...it's not hard to see once you look at it closely.

You can adjust only after travel and weight of pull.

Creep is adjusted via other means and I suggest professional help adjusting creep...I use a surface grinder.....I don't really recommend any other way.

But after you get the weight of pull down you may be happy as is....seriously...look at it and it's easy to see.

Thanks vapodog, i did find something on the net but the creep is what I wanted to eliminate. I'll adjust it first and see if I can live with it.

Otheriwse the only way I can see to reduce the creep is to shorten the sear/trigger engagement, correct?

thumb You got it....and that's why I use a surface grinder....you can control exactly how much you remove.

Well, I just found out that there is another way. A trigger is offered now that has the adjustment screw for sear travel.

Is that an after-market item? Who makes it?

Looks as though a good machineist could drill and tap an existing trigger fairly easily.

The first thing to change after the intial adjustments are made in a M70 type trigger is to a lighter spring. Don't cut a spring too short.

A way to reduce creep is to take up the sear engagement by using a dab of epoxy or solder to keep the surfaces apart. File them to fit. This works well on M77 Mk 2 triggers as well.

Also put some moly powder on the sear surfaces.
