March Scopes (Deon Optical)

Hand-built ultra-high-magnification riflescopes for benchrest, field target, and extreme long range, including the X series reaching up to 80x.

March scopes are hand assembled in Nagano, Japan by Deon Optical Design, a small manufacturer that inspects every scope twenty times and recoil-tests to 1000 Gs before it ships. Several models hold parallax down to 10 meters, which matters for field target and airgun crossover use even though March positions itself toward benchrest and extreme long range rather than airguns specifically.

Warranty: 10-year warranty from date of manufacture (tracked by serial number, extended from a prior 5-year term in 2020), 2-year on electronic components; repairs are handled directly by Deon in Japan even for later or used owners per the company's own service page, though the warranty is not stated as automatically transferable.
