RE: Dusk devil 2 "bigbulls"
The long flat pins are really nice.
They are very bright and stay bright until you can't see to shoot any way and they are actually very strong even though they are plastic. I have pressed down pretty hard on them and tried to break them but was unsuccessful. The entire sight, including the pins, has an unconditional lifetime warranty.
When you install the sight draw your bow back and anchor just like you were going to shoot with good form. You will probably notice that you can see part of the pin. The sight is made so that it can be adjusted so only the fibers dot is visible. Once you get it adjusted (very easy to do) you will instantly be able to tell if you are torquing the bow any at all. It has four adjustments. The normal vertical and horrizontal and then it has a third and fourth axis to adjust the angle of the sight to your eye so that you only see the actual aiming dot.
Yes it will fit on any bow including your Q2.
