Specifically designed for a USMC contract, the FOS (Field Observation Scope) features the durability that U.S. Optics rifle scopes are known for, but in a spotting scope configuration. The 15x-40x magnification allows the operator to view targets at extreme distances, and range them at any magnification setting using the first focal plane reticle.
With over 3 of eye relief, the FOS can be used with sun/safety glasses, gas masks and nuclear/biological disaster suits. The small 13 length allows the FOS to be easily transported and stored. Optional ARD and night vision mounts are available as well. The 6061-T6 aluminum construction with a matte black Type III anodizing protects the unit from all the abuse you can put to it.
