This is the Waters Rifleman (WR) Springfield 1903 Sight Micrometer Tool (SMT).
This tool is used to accurately and repeatably set the elevation of the rear ladder sight on your Springfield 1903 rifle to 0.5MOA increments for best accuracy.
A loving rework of the Ray Vin design in collaboration with Ray from his original designs.
- One Click = 1/2MOA
- One Revolution = 10 clicks = 5MOA
- The unit body stem increments are each worth 5MOA
- Each number increment is 20MOA
- 4 lines between each number (4 x 5MOA)
Please note: this sight micrometer tool fits the 1903 rifle only – not 1903-A3 or variants thereof.
