Three years ago — in my spare time, between range sessions — I set out to prove that 3D printing could produce a serious, competition-ready compound bow scope. Not a toy. Something you'd trust on your bow.

The answer: yes. And it does things no commercial scope offers — interchangeable reticles, eyepiece rings and body configurations, swappable in under a minute. Any light condition from dawn to midday sun.

Three versions over three years of spare time — SparrowDot V3 is range tested and field validated All is documented and free.
