Rifle Scope ZEROTECH TRACE 4.5-27x50 FFP RMG High-Transmission

Optics and image quality

The TRACE 4.5-27x50 combines a broad magnification range with a 50 mm objective to maximize light gathering and deliver a crisp image across variable conditions. FMC coatings and a Weathershield finish improve contrast and clarity while preserving performance in damp or dusty environments.

The balance between magnification and objective size provides a generous exit pupil at low power and clear definition at high power for long-range engagements. A declared 92% light transmission enhances visibility during dawn and dusk, common scenarios in mountain hunting and precision matches.

RMG reticle and accuracy

The RMG reticle is positioned on the first focal plane so subtensions remain accurate at any magnification, simplifying range estimation and hold calculations at varying distances. The reticle features 0.5 mil increments and integrated 0.1 mil stadia bars for precise holds and wind calls.

A fine floating center offers a sharp aiming point for zeroing and tight groups, while bolder markers on the outer quadrants aid fast target acquisition at low magnification and guide the eye toward the center.

Advantages for competition

In PRS and other precision disciplines the RMG layout supports both sustained engagements and rapid transitions without losing reference, thanks to its 0.5 mil steps and dense 0.1 mil bars for micro adjustments. Being FFP, the reticle maintains usefulness across magnification changes common in stage shooting.

Practical use of the stadia bars

The 0.1 mil bars allow shooters to measure and estimate range when target size is known, supplying a visual reference for applying corrections without immediately dialing the turret. The 0.5 mil increments suit quick, repeatable corrections, especially when paired with 0.1 MRAD click adjustments on the turret for fine tuning.

Turrets and Zero Stop

The Precision Turret System (PTS) integrates a reliable zero stop to return to zero after elevation adjustments. Turret indexing is set to 0.1 MRAD per click for repeatable, trackable changes in the field.

Internal travel for both elevation and windage reaches 17.8 MRAD, providing ample range for demanding ballistic corrections without external modifications.

Adjustment control and return to zero

The zero stop ensures the ability to quickly return to the original reference after multiple elevation turns, a key advantage in dynamic competition stages and variable-distance hunting scenarios. The 0.1 MRAD click value supports precise, documented adjustments that can be replicated between shots and sessions.

Turret feel and durability

PTS turrets deliver a firm, positive tactile response with audible feedback on each click. Components are engineered for frequent use while preserving repeatability and zero integrity, and the design includes spare mounting screws for straightforward field maintenance.

Construction and protection

The main tube is built from 6061-T6 aluminum for structural rigidity and compatibility with high-performance mounts. The package includes alloy HD flip-up covers to protect the lenses during transport and use.

Reticle etching on glass combined with Weathershield coatings extends durability and maintains image quality in harsh conditions. The scope carries an IPX7 water resistance rating suitable for severe weather operations.

Field resilience

The material mix and protective coatings provide robust resistance to impact, moisture, and debris. Alloy flip-up caps offer added protection during backpacking and hunting transfers, while the scope s design balances stability and handling for modern actions and chassis systems.

Frequently asked questions

What are the benefits of a first focal plane reticle?

An FFP reticle preserves subtensions relative to the target at any magnification, so mil-based graduations and measurements remain valid throughout the zoom range. This is especially useful when rapid changes in magnification are required during competition or field work.

How are the 0.1 mil bars used in practical shooting?

The 0.1 mil bars help measure and estimate range or target size when a shooter knows a reference dimension, enabling very fine visual corrections without immediately adjusting the turret. Combined with 0.1 MRAD click adjustments, they support a consistent workflow of measure, hold, and confirm.

Is this scope suitable for low-light hunting?

The 50 mm objective and high light transmission enhance performance during crepuscular periods, providing a brighter image and improved contrast compared with smaller objectives. Optical coatings and a rugged build help maintain functionality when light conditions and weather change during the hunt.
