A Live Overview of the TD-3C Red Dot Sight - A Selectable Segmented Circle Reticle

Today we've got a new piece of hardware to get sighted in at the range - the TD-3C Red Dot. This is a large-windowed red dot made for fast target acquisition with a 34 MOA segmented circle... or for precision aiming by switching to the 3 MOA dot. The reticles can easily be switched by using the +/- buttons on the side of the dot.Show more

Like the TD-3, this red dot is built to fit the RMR footprint. It comes with a picatinny adapter in the box, in case you'd like to mount it on a picatinny-equipped firearm of another sort.

Today, Chris is getting it sighted in at 25 yards on an optics-ready Glock. The sight has 1 MOA clicks, which are equal to 1/4" of adjustment at 25 yards.

00:00 Introduction
To change between the two reticles, press both the + and - buttons. The reticle will start flashing. Press either the + or - button to switch between the reticles, then double tap to confirm the reticle.

01:03 Sighting in
The first step was to get the red dot roughly sighted in over the iron sights. This isn't an exact method, but is a great way to get on paper right from the start. We're expecting a 3" group at 25 yards from this glock, but will certainly welcome a bit more precision if it presents itself.

The first group ended up having a flier off to the far left, which affected the adjustment for the second group. The second group was too far right, and had to be re-adjusted back to the left a bit. With the windage taken care of, the elevation only needed another inch of correction. Group 4 was on target within the expected group tolerances.

Adjustments can be made with a screwdriver. However, a screwdriver isn't always available - you can also use the rim of a 9mm round to fit the slots on the adjustments.

05:57 Conclusion
The red dot has been successfully sighted in at 25 yards. At this point, it's time to burn some ammo and hit some plates.
