Tech Force TF90 dot sight
I was right there when this Tech Force TF90 dot sight was being designed. I watched it evolve over several years of development, as each new model was revealed at successive SHOT Shows. I even tested a forerunner of this sight in the 1990s for The Airgun Letter by mounting it on a Beeman P1 pistol.
The Tech Force TF90 was developed by Compasseco, who used a Chinese optics factory that also made sights for their military. According to Duane Sorenson of Compasseco, the optics and manufacturing details of this sight were superior to similar Chinese-made dot sights because of who built it. In the 1990s Compasseco did a lot of business in China and had enough influence to get products designed to their specifications, and Duane was especially proud of this sight.
