Could someone please educate me or give me a web link that tells how to adjust the trigger on a withworth/interarms mark x. My the trigger on my 458 takes a healthy yank and I just don't like that also how light can you adjust it back? thanks gabe

I have an owners manual from a Interarms Mark X from about 1990. If it's the same trigger, I have the instructions.

My trigger has 4 adjustment screws. All have lock nuts.
Two on the back and two on the front.
Top Back (at a slight angle)is sear engagement adjustment
Bottom Back (behind the trigger) is Back Lash
Top front is weight of pull adjustment(this is the largest of the screws)
Bottom front( at a 45 degree angle) is the safety adjustment.

Weigth of pull instructions - screwed counterclockwise to decrease weight adjustabe 3.5 to 5 pounds.

If this sounds like your trigger I can make a copy of the page and mail it to you. Just send me a PM or email.

Biff,

I kind of pride myself as being a pretty fair trigger man when it comes to reworking/rebuilding triggers. That said, if there was ever a time for getting oneself an aftermarket trigger, this be it.

Don't get me wrong, I really like these actions and have several still in the box waiting to be built into someting, however, these adjustable triggers are crap right out of the gate and will eventually end up in my tackle box.

Have "trigger" send you the instructions for adjusting the pull, but don't expect a whole lot from these. The safety engagement/set screw is something you will want to pay close attention to after setting the sear engagement. When you operate the thumb safety, a little pointy stop screw swings in, to block the movement of the trigger lever. Yeah like that'll hold. Be careful.

Down the road, you will want to invest in one of the better aftermarket triggers for this rifle. You can go to www.brownells.com and do a search for replacement triggers for this action. Then, take the old original trigger fishing with you. Tie it about 12 inches from the bait. It will help get your bait closer to where the lunkers are...


Good luck,

I agree with you. I knew where the instructions were kept in my shop, but I had to dig around in a box or two to find the triggers. They are somewhat adjustable, but its easy and fairly inexpensive to replace them.

I have replaced both of mine. One with a Timney and the other with a Boyd. The only thing I had to do to the gun was open up the slot in the stock for the safety lever just a little.

I see no significant difference in the function of the Timney or the Boyd, but I'm working with a sample of 1 each. There are other replacement triggers available that many claim to be better.(but much mor expensive)

One day - when I run out of things to do - I will try to clean one of these triggers up. It's been 12 years now and I have not gotten around to it.

I find these triggers absolutely superb!

It is possible to get a wonderful balance of feel and crispness, adjust down to around 2lb all with that ease of taking off and on safety.

Frank de Haas' "Bolt Action Rifles" also includes adjustment instructions.

I've had two -- one was good but replaced it with a Timney because the trigger sear seemed to be worn -- it wouldn't drop-fire but also wouldn't cock consistently.

The other is still there but no longer has its safety -- I got a Gentry 3-position and Gentry threw away the factory safety lever. Excellent 3-lb. pull and I shoot this rifle better than most.

Thanks all, I have tinkered with it a little bit based on trigger's post and have to a semi acceptable place. That being said I think I will probably look at putting a timney on it along with a win style swing safety as I don't really care for trigger safties. Trigger if you don't mind I will take you up on your offer to send me the instructions just to make sure that I have done what I did right, or just for future reference. Drop me an email at gabe_stew@yahoo.com and I will send you my vitals. thanks, gabe
