From v2 to v3
Version by version. Standing on the shoulders of the last. Reaching a little further.
The entire mechanical design has been refined — tighter tolerances, cleaner assembly, more reliable swap mechanism.
V3
V2 used 0402 LEDs (1.0mm × 0.5mm) — already small. V3 moved to 0201 (0.6mm × 0.3mm), roughly the size of a grain of salt. Harder to work with, but it perfects the Dot — the precise aiming point at the center of the crosshair."
SparrowDot V3 — Cross-section view
The battery chamber is now fully integrated into the scope body — no external wiring, no exposed components. Designed specifically for the LIR2032 rechargeable cell.
Reticle and eyepiece ring now have independent brightness controls — tune each one separately to match your exact conditions.
A new saw-tooth rings behind the lens eliminates internal reflections and stray light — sharper, cleaner view.
