The March 10‑60×52 with 1/8 MOA reticle is a second‑focal‑plane, variable‑magnification riflescope built for precision shooting, bench‑rest, and long‑range work. Its 52mm objective lens and 30mm main tube give it strong light gathering, sharp optics, and a stable, machined‑metal build filled with argon gas for internal stability and durability.
