KRISS Trigger Job and Trigger picture info

Post by CatMostFeared on Mon Sep 03, 2012 11:27 pm

I like everything about my KRISS Vector but to me the trigger has alittle to much drag and creep.
On a Lyman trigger gauge on my KRISS trigger pull avg was 7lb

In this picture here is where the creep comes from the machine marks in the trigger bar.


Set it up in the vise like this


Used 1500 wet dry sand paper just to polish the trigger bar and try not to remove much material


almost done in this picture but I finished it with a polished job


I then use some rubbing compound on the trigger bar and sear.

I now have a smooth pull and its around 6lb 12oz pull
then I also removed 1 of the 2 trigger return springs and its just under 6lb pull

i was thinking about trying this. did you have to remove the upper rail in order to remove the trigger housing?

also, about how long did the total project take?

Thanks.

Yes you have to remove the top rail
It took me 2-3 hrs but I was taking my time

Trigger pull

I have done the trigger sanding and polishing as shown. I still think it is too heavy. Could you narrow this flat area or sand it into a semi-pointed surface so there is less of a contact area.

It would seem narrowing the flat would be less drag
I was going to try the same thing but just haven't yet

I started to do this, then couldn't get the top rail to budge at all. Did you have any issues getting the Loctite-sealed screws to turn? Is a heat gun okay, or too risky with the polymer?

Crap, and it didn't break?! The Armorer's Guide suggests using a nylon stock, but I wouldn't even begin to know where to find one, much less where to position it.
