Welcome to the 340 Thread and THR. We love it when post number one shows up here! Thanks for the great photos.
It's a night sight too so have fun in dark places. That front tube in the sight contains a Trijicon® Tritium vial.

Q: What is Tritium? What is “Half Life”? Why do you have only the green color?
A: Welcome to XS Sight Systems Science 101.
Tritium is a trace element naturally present in the air your breath. Tritium is Hydrogen. Hydrogen plus two extra neutrons. Hydrogen as most people know it has 1 Hydrogen isotope, 1 proton, and no neutrons. By adding 2 neutrons to basic Hydrogen you create Hydrogen3 or Tritium. The molecular structure is unstable and decays. In this decay process it throws off Beta Particles. When these Beta Particles collide with the phosphor coating on the inside of the glass tube the phosphor glows.
The term “half-life” refers to this decay process and how long the tritium vial will glow. The half-life time is how long it takes for the tritium to be half as bright as it was when new. After that point the speed of decay increases the vial brightness dies.
The color of the Tritium vial depends on the material used to coat the inside of the tube. Green Tritium vials are the brightest of all the Tritium colors. Even so they are rather weak light sources. Surprisingly small amounts of ambient light will overpower the Tritium creating a usage gap at the half to low light point of light levels. That is one of the reasons we have such a large white dot. The dot reflects any ambient present so you have full sighting ability under any light conditions.
We chose a bar and a dot because having three green Tritium fireflies out in front of you can slow your response while you decide which of them is the front sight.
Some companies try to solve this dilemma by using a different color Tritium for the front and rear sight. While this helps some, it creates addition difficulties since all the other Tritium colors are less bright than the green.
We retain the brightest Tritium color and by utilizing a vertical bar for the rear, the front sight is readily discernable from the rear so there is no loss of time in indexing the sights on the target.

the white front sight. It's awesome.
