Can you bend your sear down? Most likely have to anneal it first. Make a new sear.

I mean the sear that's pinned to the action.

Not the right size... 40 cubits? You're too short.

Aye Jack,

Can you post a pic of the top of the triggers?

Here are some photos.  One shows the top.  The next shoes the side with the knockoff portion raised as high as it will go.  The last shows the gap between the knockoff at its highest and the tail of the sear at 1/2 cock.

Jack, check the screw holding your sear spring to the top tang. It doesn't look completely seated and the sear spring will definitely change the position of your sear when properly seated. When the triggers are set, and you trip the rear trigger, does the knock off jump up and hit the sear at all? Does it jump up and go past the end of the sear? I had the same problem a few months ago with a set of triggers made by an unknown that I bought from Joe do and had to have the end of my MVA sear tig welded to add length.

Yum. Throw it on the BBQ and slap it on a bun with some mustard and sauerkraut. 
Then toss it in the trash.

Chris,
I will take your word for it.  Hard to get past the slime.

Can't believe that design allows a hole to be drilled through the spring like that. Wonder how much it weakens it and how long the service life is.

Here is a MVA sear stacked on to an original sear.  The sear tips are aligned. It shows how much higher the MVA sits.  The knockoff on the Zettler triggers hit just inside the black lines.

Jack is there any chance that that thin sear is just a close coupled DST one?   

Chris.

I asked if you got the triggers working?

Looks like the triggers will work when the MVA sear tail is bent down. No?

Maybe.  Just like you can fire a SST without setting the trigger, you can do it with the front trigger in the Zettler but it only pushes on the rear 1/16" of the sear.  If you bend it, it might not be able to do that. I am not as concerned about what happens with the Zettler, but would like to have a spare original for my two rifles that use a long tail sear since the MVA may not work on those. 
Remember my motto: when in doubt buy more parts!

Jack the close coupled sear is apparently thin like the one in your picture.  I have never looked at mine to compare, but Campbell has a picture of them in his book which I've posted.  In volume #1 he shows them but does not know why some are thick and some thin.  In volume #2 he recognises that the thick one is for the "schuetzen" triggers, and the thinner one is for the close triggers.

But about the MVA... Are you saying the long tailed sears are different than originals?  If so the MVA action has me wondering.  You've already shown pictures indicating the hammers are different and now the sears?  I was told the actions were supposed to be exact copies!

Chris.

"Tang screw" Are you talking about the wood screw? 

I have double sets and a long tailed sear on order from MVA. I assume my two original screws that hold it in an action will work.

I have purchased many MVA parts and they typically fit as advertised.  Early on I bought a single set trigger and had to sand it down in thickness to fit which was fine but the hole for the trigger catch spring was not drilled deep enough to fit their spring. It could have been drilled deeper, but I had a shorter spring.  My biggest disappointment is that their High Wall hammer, while functional is actually a low wall one which is about 3/16" short.  They did take it back no questions asked.  This long tail sear is not the right shape compared to the two originals in my rifles.

The sear could be modified but my comment is that the MVA one is not even close to being a drop in fit.  The tail is twice as thick and not at the right angle.  I will try to make it match an original. I should have taken a side by side photo of the two. I may pull the original out again since it is supposed to rain for most of the next week.  I got the deck of the ark done today. Not sure when I add on a keel or bow. I have a sneaky feeling they sent the wrong kit. Not my fault.  The wife ordered it.

I have swapped so many parts lately I can’t remember. I will install the MVA into my 32-40 DST and try it. It definitely sits higher than an original sear. 
First is dinner and a new murder mystery series. Then dishes.

Okay but now what rifle will you install the Zettler triggers in? You thought you were done but yer not done yet. 

Something interesting I hope. 

Is it accurate? Like 250 accurate?
