This is my old trigger and as you can see it's dirty. Very dirty! Now I know that grease and oil can turn hard over the years so I'm pretty sure that would be the case here. Plus being under water more than once, I don't think all the parts inside would look that good anymore.

The two screws (facing upward} that you see on my old trigger is what I messed with many years ago. They allowed me to adjust the sear engagement along with trigger pull...I think? I remember turning them until I had a reduced pull weight on the trigger, but not too much that it was unsafe. However, I've had this on my mind ever since I've played with them, thinking that someday it might not work right....or worse...have it go off when I didn't want it to.
 

To install the new trigger you just reverse the procedure from before. But one little adjustment needed to be done once in place and that was for the 'bolt removal button'. Triggertech lets you know that this adjustment might have to be done so it was no surprise and it was very easy to do. By the way, Triggertech sells this trigger with or without a bolt release button.
 

All you do is make sure the tab on the trigger lines up with the notch and you're good. If not you bend the tab a small amount till it works right and that's it. And mine needed a small adjustment like they said it might. It only took a few tries bending it and everything works great now.
 

Speaking of adjustments, to change the pull weight of the new trigger, all you have to do is turn a screw. This screw is accessible with the gun assembled with the use of a 2mm hex key. This is very easy to do and while the screw is being turned, you can feel and hear it 'click'. 
 

The hex key on the right is what came with the trigger. This wrench works fine when adjusting with the rifle stock removed from the action. However, if the rifle is assembled, the use of a 'ball hex wrench' (left) makes life much easier to adjust the pull weight. The reason is because the ball hex wrench can stay inserted in the screw while you turn it compared to the standard one that is limited because of the trigger guard being in the way (see the above picture).

With that being said, I adjusted my new trigger close to 2lbs and took it to the rifle range. This made it much easier to shoot compared to heavier pull weight. And once I was finished at the range, I readjusted it back to just over three pounds for hunting. What a great product!!!
 

I've been using a Sharpie marker to touchup my stock from day one because it's a close match and it's quick and easy. This isn't a show piece by any means because I use it every year rain or shine during deer season. And if you're a hunter, then you know things happen while you're in the woods, so this works out great for me.
 

The one thing that stands out the most now is the sling. But something that you can't see is how well it shoots now. That recoil pad works so good, I highly recommend Limbsaver. And that new trigger makes all the difference as well, I should have done this many years ago.
