Is the fixed parallax setting on the GPO Spectra 6x 1.5-9x44i suitable for close-range bush hunting in Australia?

Yes, the scope features a parallax fixed at 100 metres, making it exceptionally well-suited for point-blank out to medium-range hunting in thick Australian scrub. However, if you plan on doing dedicated precision target shooting or shooting rimfires inside 50 metres, an optic with side-focus adjustable parallax is recommended instead.

How does the iCONTROL fiber illumination perform in bright Australian daylight conditions?

The iCONTROL microdot fiber illumination system produces an ultra-fine, intensely bright red center dot within the German #4 reticle. It features continuous brightness adjustment ranging from very low dusk levels up to daylight-bright, ensuring visibility against sunlit outback backgrounds. It also includes an automatic shut-off after 3 hours of inactivity and a low-battery alert at 15% capacity using a single CR2032 coin battery.

What rings do I need to mount this scope to my rifle?

The GPO Spectra 1.5-9x44i features a 30 mm main tube diameter, so you will need standard 30 mm rifle scope rings that match your rifle's mounting rail, whether it is Picatinny, Weaver, or rifle-specific bases. If you are looking for compatible accessories in our range, you can also pair your setup with items like the Gpo Spectra Dot High Mount or a Gpo Bino Harness Pro for carrying your optics while stalking.

Will this scope hold zero and withstand heavy recoil from large magnum calibres used on Sambar deer?

Yes, the scope is engineered and structurally tested to withstand heavy recoil from magnum hunting calibres commonly used for larger Australian game like Sambar deer. It features PASSIONtrac zero-resettable capped turrets with precise 0.1 MRAD clicks and a total elevation and windage travel range of 400 cm, ensuring reliable tracking and zero retention in the field.

Hunting Rifle Scope - GPO RSX631 Spectra

The GPO SPECTRA™ 6x 1.5-9x44i (G4i Fiber) is a versatile hunting rifle scope engineered for close-to-medium range shooting in diverse field environments. Built on a 30 mm main tube, this optic combines a 6x zoom ratio (1.5x to 9x magnification) with a 44 mm objective lens to balance light transmission and a compact profile. Optical elements featuring DoubleHD™ glass and GPObright™ multicoatings deliver 90% to 92% light transmission. The second focal plane German #4 reticle incorporates an iCONTROL™ microdot fiber illumination system, powered by a single CR2032 battery, offering continuous daylight-to-dusk brightness control, a low-battery alert at 15% capacity, and an automatic 3-hour shut-off.

Who is the GPO SPECTRA 6x 1.5-9x44i G4i Fiber for?

Bush Stalkers: Benefits hunters tracking Sambar, Fallow, and Rusa deer through dense Australian scrub who require a lightweight 575 g hunting rifle scope that will not cause fatigue during all-day carry, combined with a 44 mm objective lens for low-light dusk visibility.
Running Game Hunters: Delivers a wide 28 m field of view at 100 m when set to its 1.5x low-end magnification, allowing shooters using this variable rifle scope to maintain rapid situational awareness and track fast-moving targets inside thick cover.
Pest Controllers: Provides 0.1 MRAD per click turret adjustments and a flexible 1.5x to 9x magnification range, allowing pest managers to quickly transition from close-range shots on feral pigs to precise 300-metre engagements on wild goats and foxes.

Less suitable for: Dedicated precision target shooting, extreme-range shooting beyond 400 metres, or precision rimfire inside 50 m due to the fixed 100 m parallax; a higher-magnification optic with side-focus adjustable parallax is better suited to those applications.
