What rings or mounts do I need to clear the 50 mm objective lens on my rifle?

The ZeroTech Thrive X 4-16x50 features a 30 mm main tube and an outer objective bell diameter of 58.5 mm. You will need standard 30 mm scope rings or mounts—such as Picatinny or Weaver bases—with a medium or high profile to ensure adequate clearance over your rifle barrel.

How close can I set the side parallax focus when shooting pest animals at short ranges?

The side focus parallax adjustment on this model scales smoothly from a minimum distance of 10 metres all the way out to infinity. This allows you to maintain a clear, parallax-free sight picture whether you are targeting close-range pests or shooting across open paddocks.

Does this riflescope require any batteries or electrical compliance certifications for use in Australia?

No, this is a purely passive optical and mechanical instrument featuring a non-illuminated German 4 reticle with no internal electronics. Consequently, electrical regulations such as 240V mains compatibility and SAA/RCM certifications do not apply.

What kind of warranty support do I get if something goes wrong in the field?

The Thrive X 4-16x50 is sold domestically through the local distribution network and is backed by ZeroTech's Australian Triple A lifetime warranty. This ensures full local coverage and peace of mind against manufacturing defects throughout the lifespan of the optic.

Hunting Riflescope - ZeroTech THXB4165G

The ZeroTech Thrive X 4-16x50 G4 BDC Turret is a second focal plane riflescope designed for medium-to-extended range hunting and pest management. Built around a 30 mm main tube, it combines an optical envelope of 4x to 16x variable magnification with a 50 mm objective lens to maintain light transmission and target resolution across varying field distances. Target framing is managed via a European-style German 4 (G4) reticle paired with an external Ballistic Drop Compensating (BDC) elevation dial, enabling mechanical elevation adjustments in 0.25 MOA clicks across 60 MOA of internal travel.

Who is the ZeroTech Thrive X 4-16x50 G4 BDC for?

Medium-to-extended range vertebrate pest controllers — requires the side-focus parallax that dials down to 10 metres combined with the upper 16x magnification limit to positively identify and engage small targets like foxes, feral pigs, and wild dogs out across open paddocks.
Deer and game stalkers hunting in open paddocks — leverages the light-gathering capability of the 50 mm objective lens alongside the 30 mm main tube to preserve a usable 3.0 mm exit pupil at maximum 16x magnification during dawn and dusk engagements.

Less suitable for: Thick bush stalking or running game inside 50 metres, where a low-power variable optic (such as a 1-6x or 1-10x LPVO) with a wider field of view serves the shooter better; extreme long-range and competition shooting beyond 600 to 800 metres, where a First Focal Plane (FFP) optic with dedicated milliradian reticles and greater internal elevation travel is better suited; or ultra-light backcountry mountain hunting, where a smaller 1-inch tube riflescope with a 40 mm or 44 mm objective lens better minimizes carried gear weight.
