You don't need one What you need is the trigger spring replaced and then the sear engagement is adjusted . They will often come to a 1 pound pull.

However, the entire trigger has to removed to say it is tight is an understatement. You will see a big screw when you down on the action.

The trigger needs to be taken apart to get the spring out.

Leaving the original spring then with sear engagement adjustment....small screw you see then down onto the action....they will usually come down to about 3.5 pounds won't slam fire but that is about the limit with the original spring.

Their is weight adjust at the bottom of the trigger but even if completely remove the screw it remains captive and under tension.

When testing for slam fire make sure the chamber is empty as the spring loaded ejector acts as a buffer. The Mark V is different to other push feeds because of the 54 degree bolt turn. For example if put a new case in the chamber and hold the vertical then bolt will no be in the "close down" position because of the ejection. The initial compression of the ejector is done when you push the bolt forward.

Unless you are reasonably handy and the right screw driver I would recommend taking it to a gunsmith.

Never answered my question, simply said I didn't need one.

I guess I could just get off my butt and google it.

Thanks for the detailed reply!

There is no Jewell, not sure about Timney but there was/is another make but the name escapes me.

But I can tell you that with a new spring the only way you will get better than the Mark V trigger is with a 3 lever trigger like the Jewell.

Timney makes one:

Not sure if each trigger is specified at a certain poundage as that appears in the poundage options. I think 2# would be good all around for range and hunting.

You should check with them if sear engagement and weight of pull is adjustable without taking the rifle apart....both are wit the Mark V.

By the way, with a new spring a 2 pound pull is a walk in the park with the Mark V trigger.

Also check if the trigger housing is all steel. This was a problem with German Mark Vs. Remember the bolt stop is part of the trigger on the Mark V and gets quite a slamming when that heavy bolt is pulled back real fast.
