ZeroTech Optics Riflescope Buyer's Guide: How to Choose the Right Scope

ZeroTech Optics is a precision optics brand built on over fifty years of Australian engineering heritage, delivering professional-grade riflescopes, binoculars, spotting scopes, and red dot sights to hunters, competitive shooters, and tactical professionals worldwide. Whether you're glassing a remote alpine basin or dialling in your zero at the range, choosing the right riflescope is one of the most consequential decisions you'll make as a shooter. This guide walks you through every major consideration—from magnification and objective lens size to reticle type and turret mechanics—so you can head into your next hunt or competition with complete confidence.

At 3× magnification, the scope presents an image three times larger than the naked eye; at 12×, twelve times larger. The ratio between minimum and maximum power is called the zoom ratio. A 3–12× scope has a 4:1 zoom ratio; a 4–20× scope has a 5:1 ratio. Higher zoom ratios offer greater versatility but can introduce image quality trade-offs at the extremes if the glass quality isn't there to back it up.

Matching magnification to application

Application Recommended magnification range
Close-range brush hunting 1–4× or 1–6×
General hunting (100–400 metres) 3–9× or 3–12×
Long-range hunting (400+ metres) 4–16× or 5–25×
Competitive shooting (PRS/ELR) 5–25× or 6–24×
Tactical / law enforcement 1–6× or 1–8×
Range shooting / recreational 3–9× or 4–16×

One of the most common mistakes among newer shooters is over-magnifying for their application. Cranking the power up narrows your field of view, slows target acquisition, and amplifies mirage and shooter movement. For most hunting scenarios within 400 metres, a 3–12× or 4–16× scope gives you all the reach you need while keeping a practical, usable field of view.

Objective lens size and light transmission

The objective lens—that large forward-facing glass at the business end of your scope—determines how much light enters the optical system. Larger objective lenses gather more light, which translates directly to brighter, clearer images in low-light conditions like dawn and dusk. Those are the prime feeding windows for most game animals, which means this specification has real consequences in the field.

Common objective sizes and their trade-offs

Objective diameter Light gathering Weight Mount height required
32mm Moderate Lower Standard
40mm Good Moderate Medium
44mm Very good Moderate Medium-high
50mm Excellent Higher High
56mm Outstanding Highest Very high

Larger objectives require higher scope rings to clear the barrel, raising the optical axis above the bore and potentially affecting cheek weld and shooting ergonomics. For most hunting applications, a 44mm or 50mm objective hits the sweet spot between light transmission and practical mountability.

Exit pupil

The exit pupil is the diameter of the light beam that exits the eyepiece and enters your eye. Calculate it by dividing the objective lens diameter by the magnification setting:

Exit pupil (mm) = Objective diameter ÷ Magnification

A 3–12×44 scope at 3× magnification produces a 14.7mm exit pupil—well beyond the human eye's maximum dilation of approximately 7mm in darkness. At 12×, the same scope produces a 3.7mm exit pupil, which can appear noticeably dim in low-light conditions if the eye can't dilate enough to capture the full beam.

For low-light hunting, aim for an exit pupil of 5–7mm at your most commonly used magnification setting. That's the window where your optic works with your eye, not against it.

Glass quality and coatings (preview)

Raw light gathering from objective lens size is only part of the story. The quality of the glass itself and the coatings applied to each optical surface determine how much of that gathered light actually reaches your eye with full clarity and fidelity. We cover this in detail in the Glass quality and coatings section below.

First focal plane vs. second focal plane

The focal plane position of the reticle is one of the most consequential—and most frequently misunderstood—specifications in riflescope selection. Get this right and your reticle becomes a powerful tool. Get it wrong and you're fighting your optic instead of focusing on the shot.

First focal plane (FFP)

In a first focal plane scope, the reticle sits in front of the magnification erector system. As magnification increases, the reticle image scales proportionally with the target image. This means reticle subtensions remain accurate at all magnification settings—a genuine advantage for precision long-range work.

Holdover marks and ranging hash marks are accurate at any power setting, which is why FFP is the preferred platform for precision long-range shooting and PRS competition. It enables rapid holdover corrections without resetting to a specific magnification. The trade-off: the reticle appears very fine at low magnification, which can reduce visibility in low-light conditions, and FFP scopes typically cost more because of manufacturing complexity.

Second focal plane (SFP)

In a second focal plane scope, the reticle is positioned behind the erector system. The reticle appears the same size regardless of magnification, but the subtensions of any ranging or holdover marks are only accurate at one specific magnification setting—typically maximum power.

The reticle stays clearly visible at all magnification settings, and SFP scopes are generally more accessible on price. They're well-suited for general hunting where precise holdover calculations at varying magnifications are less critical. The limitation: ranging and holdover marks only work at the calibrated magnification, so you need to dial to maximum power before using reticle subtensions for precision work.

Which should you choose?

For hunters engaging targets within 400 metres who primarily use their scope at maximum power for precise shot placement, a second focal plane scope is entirely appropriate and often the more practical choice. For long-range hunters, competitive shooters, and anyone who regularly uses holdover marks at varying magnification settings, a first focal plane scope is the right call.

ZeroTech Optics offers both FFP and SFP configurations across its riflescope lineup, so you can select the platform that best matches your discipline and how you actually shoot.

Reticle types explained

The reticle—your crosshair, your aiming reference, your ballistic calculator built right into the glass—has evolved dramatically from simple duplex crosshairs to sophisticated ranging and holdover systems that do serious work at serious distances. Choosing the right reticle for your application matters as much as any other decision you'll make when spec'ing out a scope.

Simple duplex reticle

The duplex reticle features thick outer posts that taper to a fine centre crosshair. It's fast to acquire, uncluttered, and proven effective for hunting at moderate ranges. It provides no ranging or holdover capability beyond the shooter's memorised ballistic data, but for close-to-moderate range work, that simplicity is a genuine strength.

Best for general hunting within 300 metres, brush hunting, and driven game.

Mil-dot and MOA hash reticles

Mil-dot reticles use a series of dots or hash marks spaced at precise milliradians (mils) or minutes of angle (MOA) intervals. These marks serve dual purposes: ranging targets of known size and providing holdover references for wind and elevation corrections.

  • 1 mil = approximately 3.6 centimetres at 100 metres
  • 1 MOA = approximately 2.6 centimetres at 100 metres

Mil-based systems are preferred by precision shooters and military/law enforcement users; MOA systems align naturally with how many shooters think about adjustments in terms of clicks and centimetres. The choice between mil and MOA comes down to personal preference and training background—provided the reticle and turrets are matched in the same unit of measure. Mixing systems is a recipe for confusion when the pressure's on.

ZeroTech proprietary reticles

ZeroTech engineers its own reticle systems, developed to address the practical needs of real hunters and competitive shooters in real-world conditions.

The ZeroPlex reticle is a refined hunting reticle that combines the speed and simplicity of a duplex-style aiming point with subtle holdover references for extended range work. It delivers a clean, uncluttered sight picture with enough reference marks for ethical hunting shots at distances where wind and drop become meaningful variables.

The RMG reticle (Range Mil Grid) is ZeroTech's precision long-range reticle system, featuring a full mil-based grid layout that enables rapid ranging, windage holdoffs, and elevation corrections without dialling. The RMG is optimised for first focal plane applications and built for competitive shooters and serious long-range hunters who need a complete ballistic reference system integrated directly into their optic.

The PHR reticle (Precision Hunter Reticle) is engineered specifically for the backcountry hunter who covers ground, climbs hard, and needs to be ready when opportunity presents itself. The PHR balances the clean sight picture demanded for quick shots in the field with the holdover capability required for extended-range engagements. Wind dots and elevation marks are positioned to minimise clutter while maximising practical utility across the all-weather scenarios backcountry hunters actually face.

A reticle that doesn't match your shooting application adds complexity without benefit—or worse, leaves you without the reference marks you need at the moment that matters most.

Turret systems and zero retention

Turrets are the adjustment knobs on the scope body that control elevation (top turret) and windage (side turret). Their quality, precision, and mechanical design directly determine whether your zero holds under recoil, temperature swings, and extended field use. In demanding conditions, turret performance isn't a minor detail—it's the difference between a hit and a miss.

Capped vs. exposed turrets

Capped turrets feature a protective cap over the adjustment mechanism. They're the go-to choice for hunting applications where an inadvertent adjustment in the field—from brush contact or pack straps—would be a disaster. Dial in your zero at the range, cap it, and trust it in the field.

Exposed turrets (also called target or tactical turrets) feature large, easily gripped knobs designed for rapid on-the-fly adjustments. They're the standard in precision rifle competition, tactical applications, and long-range hunting where shooting conditions demand frequent elevation changes between shots.

Zero stop mechanism

A zero stop is a mechanical feature that lets you set a hard stop at your established zero. When dialling down from an elevated position, the turret stops at zero and can't be inadvertently dialled below it. This eliminates a critical error source in high-pressure field situations where you may lose track of turret position. For any scope running exposed turrets in hunting or tactical applications, a zero stop isn't optional—it's essential.

Click value and repeatability

Turret click values are expressed in either MOA (typically ¼ MOA per click) or mils (typically 0.1 mil per click). Repeatability—the ability of the turret to return to a previously set position with mechanical precision—is a function of internal component quality and manufacturing tolerances.

ZeroTech applies aircraft-grade aluminium construction and precision-machined internal components across its riflescope lineup, ensuring turret adjustments track accurately and return to zero reliably after every outing, regardless of conditions.

Tracking test

Before trusting any riflescope in the field, run a tracking test (also called a box test or tall target test):

  1. Fire a group at your zero
  2. Dial a known number of clicks in one direction (e.g., 20 MOA up)
  3. Fire another group—it should be precisely displaced from the first
  4. Return to zero and fire a final group—it should overlay the original

A scope that fails this test has mechanical issues that will compromise field performance regardless of glass quality. Know your gear before you need it.

Glass quality and coatings

The optical system of a riflescope is defined by two primary factors: the quality of the raw glass and the coatings applied to each air-to-glass surface. Together, these determine light transmission percentage, colour accuracy, edge-to-edge sharpness, and resistance to glare and flare. This is where precision optics earn their reputation—and where ZeroTech's fifty-plus years of optical heritage delivers real, visible results.

Glass types

Standard crown glass is the baseline optical glass used in entry-level optics. It's workable for general use but subject to chromatic aberration—colour fringing at high-contrast edges—at higher magnification settings. It gets the job done at close range but shows its limitations at distance.

Extra-low dispersion (ED) glass is formulated to minimise chromatic aberration by reducing the dispersion of light across the visible spectrum. The result is sharper, higher-contrast images with accurate colour rendition, particularly at extended ranges and in low-light conditions. ZeroTech incorporates ED glass across its premium product lines, delivering optical performance that competes directly with optics sold at significantly higher price points.

Lens coatings

Every air-to-glass surface in a riflescope reflects a small percentage of incoming light. A multi-element scope can have a dozen or more such surfaces. Without coatings, total light transmission can fall below 70%. Quality multi-coating systems push transmission above 90%, with premium coatings reaching 95% or higher. That difference is visible—and it matters most when the light is fading and the shot clock is running.

Term Meaning
Coated Single anti-reflection layer on some surfaces
Fully coated Single layer on all air-to-glass surfaces
Multi-coated Multiple layers on some surfaces
Fully multi-coated Multiple layers on all air-to-glass surfaces

Fully multi-coated is the standard to demand in any serious hunting or precision shooting optic. ZeroTech applies fully multi-coated lens systems across its riflescope lineup, ensuring maximum light transmission and image fidelity from first light to last.

Dielectric prism coatings

In binoculars and spotting scopes using Bak 4 prisms, dielectric coatings dramatically improve reflectivity within the prism system, pushing light transmission towards 99% per reflection. ZeroTech incorporates dielectrically coated Bak 4 prisms in its binocular and spotting scope lines, producing images that are bright, sharp, and colour-accurate even in demanding low-light conditions.

Durability and environmental ratings

A riflescope faces mechanical shock from recoil, temperature extremes from pre-dawn frost to midday heat, moisture from rain and condensation, and the physical punishment of serious backcountry travel. Environmental durability isn't a luxury feature—it's a basic requirement for any optic that's going to earn its place in the field.

Waterproofing

Quality riflescopes are sealed with O-rings to prevent water ingress. IP-rated (Ingress Protection) housings provide standardised waterproofing levels verified through rigorous testing. ZeroTech builds its riflescopes to IP-rated standards, ensuring reliable waterproofing across immersion depths relevant to real field conditions.

Fogproofing

Internal fogging happens when temperature changes cause moisture to condense on internal optical surfaces—a critical failure point that can cost you the shot of a lifetime. The solution is purging the internal atmosphere with an inert gas—either nitrogen or argon—before sealing the tube. Argon molecules are larger than nitrogen molecules, making argon purging more effective at preventing internal moisture migration over the long term.

ZeroTech uses argon purging across its riflescope lineup, delivering superior fogproof performance in rapid temperature transition environments. Hunters in the far north have reported zero fogging in conditions as cold as -22°C—real-world validation from real hunters in genuinely brutal conditions.

Shockproofing

Recoil generates significant G-forces on a scope's internal components with every shot. Magnum calibres, particularly large-bore dangerous game rounds, can produce recoil impulses that destroy scopes not engineered for the task. Aircraft-grade aluminium tube construction and precision-fitted internal components ensure that ZeroTech riflescopes maintain zero and optical integrity across the full spectrum of calibres and recoil profiles.

Field-proven performance

ZeroTech products have been tested and validated in environments as extreme as the frozen wilderness of the far north and the Australian outback—the kind of conditions that expose every weakness in materials, sealing, and construction. That field record, earned through genuine use in genuinely demanding country, defines the durability standard ZeroTech builds to.

Tube diameter: 1-inch vs. 30mm vs. 34mm

The main tube of a riflescope—the central body section housing the erector system—is manufactured in standardised diameters that determine mounting compatibility and internal adjustment range. Understanding the trade-offs here helps you build a complete, optimised shooting system from scope to rings to rifle.

1-inch (25.4mm) tubes

The traditional standard in riflescope design. One-inch tubes are compatible with the widest range of rings and mounts, are generally lighter, and are entirely capable for hunting applications within moderate ranges. The smaller tube diameter limits the total internal adjustment range available, which can become a constraint for extreme long-range applications or when mounting on rifles with significant scope-to-bore offset. For many hunters, though, a quality 1-inch scope is all the optic they'll ever need.

30mm tubes

The current dominant standard in mid-to-high performance riflescopes. Thirty-millimetre tubes provide greater internal adjustment range than 1-inch tubes, accommodate brighter erector systems, and offer a wider selection of precision mounting hardware. The weight penalty over 1-inch tubes is modest. For most hunters and competitive shooters, 30mm is the practical choice that covers the widest range of serious shooting applications.

34mm tubes

Found primarily in top-tier precision and long-range competition scopes. Thirty-four-millimetre tubes maximise internal adjustment range—critical for extreme long-range applications where large elevation corrections must be dialled—and support the largest erector systems for maximum optical performance. The trade-off is increased weight and a more limited selection of compatible mounting hardware.

Practical guidance:

  • General hunting: 1-inch or 30mm
  • Long-range hunting and competition: 30mm or 34mm
  • Extreme long-range / ELR competition: 34mm

Eye relief and eye box

Eye relief

Eye relief is the distance between the eyepiece lens and your eye at which the full field of view is visible. It's a critical safety consideration on hard-recoiling firearms—one that shooters sometimes overlook until they learn the hard way.

Insufficient eye relief on a hard-recoiling rifle results in scope bite—the eyepiece making contact with your brow under recoil. Painful, potentially dangerous, and entirely avoidable. Standard eye relief for centrefire rifle scopes runs approximately 7.5 to 10 centimetres. Dangerous game rifles and heavy magnum calibres benefit from scopes offering 10 centimetres or more. Know your rifle's recoil characteristics before you spec your scope.

Eye box

The eye box describes the three-dimensional volume within which your eye can be positioned and still achieve a full, clear sight picture. A generous eye box allows for slight variations in head position and speeds up target acquisition—particularly important in hunting scenarios where shots are taken from improvised positions under genuine time pressure. In the field, you rarely get to set up perfectly. Your optic should work with you anyway.

Eye box generosity is a function of optical design and isn't directly advertised in most specification sheets. Field reviews from experienced hunters and shooters provide the most reliable real-world assessment of a scope's practical eye box performance.

Parallax adjustment

Parallax is an optical phenomenon in which the reticle appears to shift position relative to the target when your eye moves off the optical axis. At ranges where parallax is significant, this apparent shift introduces aiming error that no amount of marksmanship technique can correct.

Fixed parallax

Many hunting scopes are set at the factory with a fixed parallax—typically 100 metres. At this distance, parallax error is eliminated. At significantly shorter or longer distances, some parallax may be present, though it's often negligible within the magnification ranges used for general hunting. For most hunters shooting within 300 metres, a fixed parallax scope does everything required without adding complexity.

Adjustable parallax (AO / SF)

Precision and long-range scopes incorporate adjustable parallax, accessible either through an adjustable objective (AO) ring at the front of the scope or a side focus (SF) knob on the left side of the turret housing. The side focus configuration is preferred for its ergonomic accessibility—you can adjust without disturbing your shooting position or breaking your cheek weld.

Setting parallax correctly at each engagement distance eliminates parallax-induced error and, as a secondary benefit, sharpens the image of the target in the focal plane. For any shooting beyond 300 metres, adjustable parallax is a worthwhile and often essential feature.

Warranty and long-term value

A riflescope is a long-term investment. The warranty backing that investment matters as much as any optical specification—because even the finest precision optics can be damaged in the field, and the manufacturer's response to that damage defines the true cost of ownership over the life of the product.

The ZeroTech Triple A Lifetime Warranty

ZeroTech backs every product with the Triple A Lifetime Warranty: Any owner. Any problem. Always covered.

This isn't a standard limited warranty loaded with exclusions, paperwork requirements, and depreciation schedules. The Triple A Warranty is unconditional:

  • Any owner: The warranty is fully transferable. Sell your ZeroTech scope and the warranty transfers to the new owner automatically—no registration, no paperwork, no questions asked.
  • Any problem: Manufacturing defects and accidental damage are both covered. No exclusions for field use, hard hunting conditions, or environmental damage.
  • Always covered: For the lifetime of the product. Not two years. Not five years. The lifetime of the optic.

This warranty reflects ZeroTech's confidence in its engineering and materials. It also has real financial implications: a ZeroTech scope that takes a hit in the field is repaired or replaced at no cost, eliminating the hidden cost of ownership that accompanies less comprehensively warranted optics.

Transferability and resale value

Because the Triple A Warranty transfers with the optic, ZeroTech scopes retain stronger resale value than non-transferable warranty alternatives. A used ZeroTech scope carries the same unconditional coverage as a new one—a differentiator that informed buyers recognise and value.

Comparing warranty value

When evaluating riflescopes at similar price points, factor the warranty into your total cost of ownership calculation. An optic priced slightly higher but backed by an unconditional lifetime transferable warranty often represents better long-term value compared to a less expensive alternative with a limited, non-transferable warranty that excludes accidental damage.

ZeroTech's Triple A Lifetime Warranty consistently ranks as a primary purchase driver amongst customers who have experienced the limitations of other warranty programmes—real-world feedback from hunters and shooters who've seen the difference when it matters most.
