Will the 9.9-inch length of the GPO Centuri Super Compact cause mounting issues on my rifle?

Due to the short 9.9-inch overall tube length, rifles featuring wide bridge bolt-actions may require offset or cantilever rings, or a continuous Picatinny rail to achieve proper eye relief and ring spacing. It is designed to fit standard 30 mm scope rings and mounts commonly used on Australian shooting platforms.

How close can I focus this scope for rimfire pest control or short-range shooting?

The side focus parallax adjustment on the RC420 allows you to focus down from 10 yards all the way out to infinity. This close 10-yard focus capability makes it exceptionally well-suited for rimfire pest control, airgun use, or fast acquisition in dense Australian bush conditions.

Does the illuminated reticle require any special Australian electrical compliance or mains charging?

No mains power or electrical compliance certifications like RCM or SAA are required, as the reticle illumination is powered entirely by a single, user-replaceable 3V CR2032 coin cell battery. The scope also features GPO's iControl auto-off system to help conserve battery life during extended multi-day hunts.

Compact Rifle Scope - GPO Centuri RC420

The GPO (German Precision Optics) CENTURI™ Super Compact 3-12x44i (model RC420) is a compact hunting rifle scope engineered for stalking, mountain hunting, and short-action shooting platforms. Measuring 9.9 inches (approx. 251.5 mm) in overall length and weighing 18.9 oz (approx. 535.8 g), this optic provides a 3–12x magnification range paired with a 44 mm objective lens. Optical performance is driven by Double-HD objective glass, GPObright™ high-transmission anti-reflective lens coatings, and PASSIONdrop™ hydrophobic external coatings. Target acquisition in low light is supported by a Second Focal Plane (SFP) G4i micro-dot illuminated fiber reticle powered by a single CR2032 3V battery with an iControl™ auto-off system.

Key Features

Super Compact Footprint: Designed with a short 9.9-inch length to maintain optimal rifle balance and conserve mounting rail space on lightweight platforms.
Illuminated G4i Reticle: Utilises a fine fiber-optic micro-dot in the second focal plane with iControl™ auto-off power management to preserve battery life.
Side Focus Parallax: The third-turret parallax adjustment focuses smoothly from 10 yards (9.1 m) out to infinity.
Protected Turrets: Capped, reset-to-zero elevation and windage turrets adjust in 1/4 MOA click increments with 100 MOA of total adjustment range.
Robust 30 mm Main Tube: Fits standard 30 mm mounting rings and accommodates recoil forces from rimfire up to big-bore centrefire calibres.

Who is the GPO Centuri Super Compact 3-12x44i G4i Fiber for?

Backcountry and Mountain Hunters — Reduces rifle carry weight and overall bulk during active stalks with a low 18.9 oz weight and an ultra-short 9.9-inch footprint on lightweight mountain hunting platforms.
Rimfire Pest Control Shooters — Delivers sharp target focus and eliminates parallax error on close-range targets with a side-focus system that adjusts down to 10 yards.
Short-Action and Compact Platform Shooters — Fits modern compact sporting rifles and short-action receivers without protruding past the barrel or interfering with ejection, providing 3–12x magnification across a 44 mm objective lens.

Less suitable for: Long-range precision shooters requiring exposed dialling and first focal plane mil-grid reticles, who are better served by dedicated long-range tactical optics with exposed turrets and FFP configurations. Additionally, rifles featuring wide-bridge bolt actions may require cantilever mounting rings or a continuous Picatinny rail due to the scope's 9.9-inch overall tube length.
