Tikka trigger spring fail

[longrangelead]

Was this one of the McCarbo springs from FL?

from UM. don't know maker.

Only one end of that pin (the correct end) can be inserted into the spring. The other end is too fat. Isn't that what keeps people from installing it backwards... the fact that you can't?

Tikka may have fixed the post making it “fatter” to prevent it being installed backwards. I know it’s easy to do, or at least it used to be, with a light trigger spring.

For that main trigger assembly screw I normally paint pen the threads and then use needle nose pliers wrapped in a rag to hold the mag catch tab in place (it tends to clock when tightening the screw). I then tighten it until the long end of the 90 degree allen wrench bends. Tight tight.

Does the type/brand of paint pen matter?

I purchased a Tikka trigger sprint from UM about a year ago. I found it to be way too light at all adjustment levels, and immediately removed it.

I know a lot of instructors that would eject you from the course for that kind of failure, no matter the cause.

I’ve had good luck with the oil based paint pens from Amazon so far.

I wonder what it is about the factory spring that makes it so much more reliable then. Not sure if it's the type of metal used, the coating, the spring tension of the heavier weight, or what.

Likely D: All of the above.

@mxgsfmdpx can you get the part number for a Sako S20 two stage trigger?

Tried out any KRG Midas triggers @Formidilosus enough to see reliability?

Most after market springs are just repurposed pieces of shit springs from a click pen or something marked up about 8000 percent

The two stage right handed is this one…

There appears to be some variability in the minimum pull weights guys get with their factory springs. Is there a place I can buy factory springs from? Mine goes down to 2.6# right now and I'd love it if I could find a factory spring that allows pull weight down to like 2# - 2.25#

Edit: Either that or I may try filing down the trigger screw a little bit so the tensioner on the trigger spring can back out a bit further. I've seen that mentioned as a possible solution as well.
