The Photo Gear Designs ESM-1 (External Sight Mount) design is the result of an evolution and refinement of a simple but extremely precise design. It is built in the USA using the highest quality structural and UV resistant plastic, machined to very close tolerances on modern CNC equipment. The mount rail is aircraft grade aluminum machined to the minimum necessary dimensions. It is anodized for lifetime reliability. The ESM-1 is very strong and rigid yet weighs only 27 grams!
While testing the ESM-1 we discovered an ideal optical reflex sight with the qualities we desired:
- A large lens for the projected reticle with minimum field of view obstruction
- Multiple reticle styles
- Red and Green reticle colors
- Rugged design and good weather resistance
