What mounting rings do I need for the GPO Centuri RC450, and will it fit my rifle setup?

The Centuri RC450 requires standard 30 mm mounting rings. Due to its ultra-compact 9.9-inch length, the tube space between the turrets and optical bells is quite short, meaning extra-long magnum receivers may require extended Picatinny bases or cantilever mounts to achieve proper eye relief.

How does the compact size and weight perform during multi-day backcountry hunts in the Australian bush?

At only 9.9 inches in length and weighing just 20 ounces, the RC450 is specifically built for lightweight mountain and scout rifles to minimise bulk on long-range stalks. Its double HD laminated glass and GPObright fully multi-coated optics maintain sharp clarity during dawn and dusk low-light transitions.

What is the minimum focus distance for close-range shots or rimfire use?

The side focus parallax turret on the RC450 adjusts seamlessly from 10 yards out to infinity. This short minimum focus distance makes it exceptionally versatile for close-range targeting, rimfire setups, and medium-to-long-range hunting alike.

Are there any electrical safety or SAA/RCM compliance requirements for the illuminated reticle in Australia?

No, SAA electrical certifications and RCM compliance do not apply to passive rifle optics of this category. The scope operates entirely as an unpowered optical sight, using a standalone CR2032 3V coin cell battery exclusively to power the reticle illumination.

Compact Rifle Scope - GPO Centuri RC450

The GPO Centuri Super Compact 4-16x44i FFP (RC450) is a compact first focal plane riflescope engineered for platforms where standard-length optics create excessive bulk or mounting interference. Measuring 9.9 inches in total length and weighing 20 oz, it combines Double HD laminated glass and GPObright fully multi-coated optics with a 30 mm main tube. It features an illuminated PLRi MIL-based Christmas-tree reticle in the first focal plane, paired with 0.1 MRAD counter-clockwise zero-stop locking ballistic turrets, providing 22 MRAD of total elevation adjustment and side parallax focusing from 10 yards to infinity.

Key Features

Ultra-Compact Profile: Total overall length of 9.9 inches (~251.5 mm) prevents mounting overhang on short receivers and reduces overall firearm bulk.
First Focal Plane PLRi Reticle: Keeps sub-tensions accurate across the entire 4x to 16x zoom range, powered by a CR2032 coin cell for reticle illumination.
Precision Turrets: 0.1 MRAD tactile adjustments with CCW rotation, integrated Zero-Stop elevation locking system, and 36 MRAD of windage travel.
Close-Focus Parallax: Side-focus adjustment wheel corrects parallax from 10 yards (~9.1 m) out to infinity.
Ruggedised Construction: Nitrogen-purged, waterproof housing equipped with PASSIONdrop hydrophobic lens coatings and standard 30 mm ring compatibility.

Who is the GPO Centuri Super Compact 4-16x44i FFP for?

Lightweight Mountain Hunters — Needs a low-profile compact first focal plane riflescope that minimizes carry weight without sacrificing optical reach, utilizing an overall length of 9.9 inches and a weight of 20 oz on short-action mountain rifles.
Scout and Compact Bolt-Action Shooters — Requires reliable trajectory holdovers and windage compensation across varied distances, enabled by the 22 MRAD elevation range and the mid-range 4-16x magnification envelope.
Modern Sporting and Tactical AR Platform Shooters — Seeks a short-footprint riflescope that preserves top-rail space and balances compact chassis systems, featuring a 44 mm objective lens diameter for clearance and low-light light transmission.

Less suitable for: Close-range shooting under 50 metres requiring instant snap engagement (where a dedicated 1-6x or 1-8x low-power variable optic or unmagnified red dot sight provides a wider true 1x field of view), extreme long-range competition beyond 800 to 1,000 metres (where larger 34 mm tube optics with 25x to 35x magnification and 50 to 56 mm objectives are optimal), or extra-long magnum bolt-action receivers where short ring spacing necessitates cantilever mounts or extended rail bases to achieve proper eye relief.
