March-FX 4.5-28x52 High Master

• High Master lens system: Super ED and high-refractive-index lens elements help reduce chromatic aberration and shimmer, giving a cleaner image at long range where small aiming errors become more visible.
• 4.5-28x wide zoom range: The magnification span covers everything from closer positional work to precise long-range shooting, so one riflescope can handle varied distances and target sizes.
• First focal plane reticle: The reticle scales with magnification, keeping holdovers and ranging references consistent across the zoom range for faster corrections in practical field and match use.
• 34 mm main tube with 30 mrad elevation: The large adjustment range supports dialing for extended distances while still leaving room for zeroing and rifle-specific setup.
• Side focus and Zero Stop turrets: Parallax adjustment from 10Yds-infinity sharpens the target at different distances, while the Zero Stop system makes it easier to return quickly to a known zero after dialing.

About the March FX Series

March-FX is a current riflescope family from March built around a first focal plane reticle and a 34 mm main tube, aimed at shooters who want one optic to cover practical field use, competition and long-range work. Within the March lineup, the FX series sits as a versatile variable-power range with models that stretch from low-power configurations such as 1-10x24mm up to high-magnification options including 5-42x56mm and 5-40x56mm. That spread gives the series a broad role across hunting optics and tactical optics without changing the core design approach.

A defining trait of the series is its emphasis on compact, mechanically precise scopes with reticles that remain usable throughout the magnification range. The current March-FX range includes the 4.5-28x52mm model seen here, alongside other configurations for shooters who prioritize either wider versatility or more top-end magnification. Across the family, the combination of FFP layout, a robust tube format and March’s focus on optical refinement makes the FX series especially relevant for users who dial regularly, shoot at changing distances and need a reticle that stays proportionate as magnification changes.

About the March-FX 4.5-28x52 High Master

The March-FX 4.5-28x52 High Master is built for shooters who want substantial magnification in a relatively compact long-range riflescope. Its 4.5-28x range gives it a broad working envelope: the lower end is useful when a wider view and faster target acquisition matter, while the upper end helps with precise shot placement, reading small targets and refining holds at distance. Combined with a 52.00 mm objective lens, the scope balances reach, brightness and practical size for precision shooting, competition use and demanding hunting applications.

This model stands out for its High Master lens system, which uses Super ED elements to control color fringing and preserve image definition when mirage, contrast transitions and fine target detail make ordinary optics work harder. The first focal plane design keeps reticle subtensions valid through the zoom range, which is a real advantage when magnification must change between stages or shooting positions. Red illumination improves reticle visibility against dark backgrounds without changing the reticle’s underlying scale.

Mechanically, the scope is configured for dialing. It uses tactical turrets with Zero Stop, 10 MIL/20 MOA per turn and a 30.00 mrad elevation range, giving the shooter enough travel for serious distance work while keeping return-to-zero straightforward. Side focus parallax adjustment from 10Yds-infinity helps maintain a sharp target image across short and long distances, and the fast-focus eyepiece speeds reticle setup to the shooter’s eye. A 34 mm tube, argon filling, and waterproof, fogproof and shockproof construction round out a scope designed for repeated field use rather than occasional bench shooting.

About March

DEON Optical Design Corporation was established in 2004 in Japan and is headquartered in Chino, Nagano Prefecture. The company designs and manufactures the March brand of custom rifle scopes, with assembly carried out in Japan using Japanese-made components. March has built its reputation around specialized riflescopes for demanding precision shooting applications rather than broad mass-market optics.

The company’s product lines include March-FX, March-X, Genesis and High Master riflescopes, each aimed at different shooting disciplines and adjustment concepts. DEON introduced its first March 40×52 mm benchrest scope in 2007, and later brought Super ED lenses into the March range in 2017. That optical development is directly relevant here, as the High Master lens system combines Super ED and high-refractive-index lens elements to improve image quality in high-performance riflescopes.
