Home Forums Hunting & Shooting Gunsmithing Interarms Mark X--trigger adjustment

In the pic the top nut and piece of threaded rod are for adjusting the amount of sear contact I assume. Anybody know for sure?

I thought about tuning it, for practice, before going to the smith.

Thanks,

Mike

That is not the original trigger... Or at least it is not like any of mine or any of the many I have seen. It is not like any Timney I have seen.

Probably the top rear screw is sear engagement, bottom rear is pull weight and there is an overtravel adjustment on the front...

Sikta,

Art, That IS an original Mark X trigger...

They did use the old simple FN military/sporting style single stage trigger on the very earliest Mark X actions but by the mid 1970s they had the steel housing adjustable units.

I have seen many of them.

They continued using them on the last Mark Xs and I believe the newer Daly/Remington 798 have them as well.

My 1978 vintage Mark x has an identical unit..

You were spot on as to where the adjustments were.

My advice to anyone adjusting these is beware of the slop in the adjustment screws. Once you get it set to your liking, go back and EPOXY those screws in. And likewise epoxy the lock nuts down. That m98 firing pin really rocks those units and WILL vibrate things loose.

Also, be sure and properly adjust the safety tumbler screw so that when the engagement is set, the safety goes in to position positively and there is NO movement of the trigger when put in the safe position.

Thanks for the correction! I have taken quite a few of these apart and have never seen one. The three I have on hand right now are all very simple.

I'm going to mess with it, then if I mess it up Roger Ferrell can fix it

I just want to practice..

Do they normally adjust pretty well? Say a smooth 4-LB's

While I haven�t worked on that exact model of trigger myself, I think Sitka Deer is wrong in his description of which adjustment screw does what. I am fairly near certain that the top screw at the front of the housing is for let-off weight adjustment, and the lower screw at the rear of the housing is the over-travel adjustment.

ROTR � you can find out quite easily which is which. Slacken the lock nut on the top front screw, and remove the screw completely from the housing. Take the final turns VERY CAREFULLY, because if I am correct, a compression spring located under the screw will come flying out!

If there is NO spring in there, then I am wrong, and the lower screw at the rear would be for weight adjustment, and should have a spring under it � but I very much doubt it, because there just isn�t enough depth there. The spring would have to be so short that it would be almost useless for let-off weight adjustment.

I'll check it out when I get home from court tonight.

my daly has an excellent trigger

"Top front screw", pull weight
"Upper back screw", sear engagement
"Lower back screw", trigger stop/over-travel

Thanks!

I just got in and don't really feel like fooling with it tonight.

The big trick with that style of Mark X trigger is not adjusting the trigger--but adjusting the trigger and having the safety still work reliably. Often if that's the case, then the trigger break isn't quite as good as it might be.

If you have a 3-position type safety installed, the Mark X trigger can get really good.....

Thanks Mule Deer that is what it is destined to have. Since I tinkered with my 10/22 by putting a volquartson hammer and various other parts in it and a little fooling with my Rem 700 trigger assy I'm not totally scared of them anymore so I wanted to mess with it a little before it's gone south.
