What rings or mounts do I need to attach the GPO Centuri 4-16x44i to my rifle?

The Centuri 4-16x44i features a standard 30 mm main tube diameter, requiring compatible 30 mm scope rings or mounts to fit your rifle's Picatinny or Weaver rail base. It has an approximate length of 14.5 inches and a 44 mm objective lens, so ensure your ring height clears the barrel adequately.

Can I use this scope for close-range rimfire pest control as well as longer-range big game hunting?

Yes, the side parallax adjustment on the GPO Centuri 4-16x44i dials down to a minimum of 10 yards and extends out to infinity. This makes it versatile enough for close-range rimfire pest control while providing up to 16x magnification and clear double HD glass for centrefire engagements well beyond 500 metres.

How does the G4i Fibre reticle perform in low-light hunting conditions out in the bush?

The G4i reticle combines heavy German #4 style outer posts to draw your eye quickly to the target with a fine, illuminated micro-dot fibre center. Powered by an internal CR2032 coin-cell battery, the illumination provides precise shot placement in dim dawn or dusk conditions without washing out or obscuring your target.

Does this rifle scope require any specific electrical safety certifications or permits for use in Australia?

The Centuri 4-16x44i is an unregulated optical aiming device powered exclusively by an internal 3V coin battery rather than mains electricity, so it does not require 240V SAA electrical safety approvals or RCM compliance markings. It is standard for legal sale and use across Australian states and territories subject to local firearm carriage regulations.

GPO Centuri 4-16x44i Scope - GPO RCX441

The GPO Centuri 4-16x44i (G4i Fibre Reticle) is a second focal plane rifle scope engineered for medium-to-long-range hunting and precision target shooting. Built on a 30 mm main tube, it combines double HD glass optical elements with an illuminated German #4-style micro-dot fibre reticle. The optical system delivers 0.25 MOA click adjustments paired with Zero-Stop locking ballistic reset turrets, allowing shooters to adjust elevation reliably in the field and return precisely to zero without losing tracking. Side parallax focus adjusts from 10 yards (9.1 m) out to infinity, providing sharp target focus across both close-range pest control and extended long-range centrefire setups.

Key Features

Double HD Optical Glass: Fully multi-coated optical elements maximize light transmission and edge-to-edge clarity across the entire 4x to 16x zoom range.
Illuminated G4i Fibre Reticle: Second focal plane German #4 crosshair configuration features bold outer posts and a fine, battery-powered micro-dot (CR2032) for rapid target acquisition in low-light environments.
Zero-Stop Turrets: Integrated elevation zero-stop mechanism prevents accidental adjustment past primary zero and allows rapid reset after dialling for distance.
Wide Parallax Range: Third-turret side focus dials smoothly from 10 yards (~9.1 m) to infinity, eliminating parallax error on both rimfire and centrefire platforms.
Rugged Weatherproof Construction: Nitrogen-purged, waterproof, and fog-proof 30 mm aluminium chassis designed to withstand recoil from calibres ranging from .22LR to .300 Win Mag.

Who is the GPO Centuri 4-16x44 G4i Fibre for?

Medium-to-long-range big game hunters — Delivers a versatile 4x – 16x magnification range and a 44 mm objective lens housed in a 30 mm main tube, giving hunters an uncluttered second focal plane reticle with precise 0.25 MOA turret adjustments for clean shot placement in low light.
Rimfire and centrefire pest control shooters — Features a side parallax adjustment that dials down to 10 yards (9.1 m) combined with a precise 0.25 MOA click system, allowing this second focal plane rifle scope to transition seamlessly between close-quarter small game and long-range varmint eradication.

Less suitable for: Shooters requiring rapid, snap-shooting target acquisition under 25 m in thick scrub, who are better served by a 1–6x or 1–8x low-power variable optic (LPVO); and long-range precision match competitors needing active reticle holdovers across varying magnifications, who are better suited to a first focal plane (FFP) optic featuring a graduated MIL or MOA tactical tree reticle.
