Is the Sightron SI-74007 a complete riflescope or just an accessory turret knob?

The SI-74007 is an aftermarket accessory turret knob designed to replace or customize the elevation turret on compatible Sightron SIII riflescopes, not a complete scope. It features a 0.1 MRAD adjustment click value and a 14.5 MRAD engraved scale for rapid tactical dialling.

Will this elevation knob fit MOA-configured Sightron SIII scopes?

No, this specific model (SI-74007) is built specifically for metric/milliradian variants of the Sightron SIII series utilizing tactical metric turrets. It is not compatible with MOA-configured turrets, such as the Sightron SI-25003 or SI-25139 models which use MOA and fine crosshair reticles.

Are there any specific Australian electrical or firearms licensing compliance permits required to purchase this turret knob?

No electrical compliance mandates such as 240V compatibility, SAA approval, or RCM marks apply since this is a fully mechanical optical accessory requiring no batteries. Furthermore, un-serialized shooting hardware accessories like turret knobs are exempt from standard firearms licensing restrictions or import permits across all Australian states and territories.

How does the 14.5 MRAD travel limit perform for extreme long-range shooting in outback conditions?

The engraved scale offers 14.5 MRAD of total dial travel, which comfortably takes common calibres like .308 Win or 6.5 Creedmoor out to 1,000 metres and beyond depending on your muzzle velocity and base cant. For extreme long-range shooting requiring adjustments exceeding 14.5 MRAD in a single revolution, an optic with a 34mm maintube like the Sightron SV Series (SI-27001) with a Mil-Hash reticle may be more suitable.

Tactical Elevation Knob - Sightron SI-74007

The Sightron SIII Series 6-24x50mm Tactical Elevation Knob (Part # SI-74007) is an aftermarket accessory dial designed to replace the standard elevation turret on compatible Sightron SIII 6-24x50 riflescopes. It converts compatible optics for exposed tactical dialling, eliminating the need to calculate conversions between Imperial clicks and metric reticles. Engineered specifically for metric and milliradian variants within the Sightron SIII lineup, this fully mechanical knob interfaces directly with the optic's internal screw pitch to provide precise, repeatable elevation adjustments in the field or on the firing line.

Key Features

Tactical Knurled Profile: Built with an aggressively textured, exposed outer rim that allows slip-resistant grip and fast adjustment when wearing gloves or operating in adverse weather.
Direct Metric Tracking: Delivers 0.1 MRAD (1 cm at 100 m) adjustment click values for 1:1 correlation with metric reticles such as Mil-Dot and Mil-Hash patterns.
Laser-Etched Scale: High-contrast laser engravings provide clear visibility up to a total dial travel of 14.5 MRAD in a single rotation.
Centrefire Recoil Integrity: Fully compatible with the recoil forces of standard and magnum centrefire calibres supported by the Sightron SIII ExacTrack system.
Mechanical Simplicity: Requires no batteries, electrical power, or specialised installation permits for use across Australia.

Who is the Sightron SIII Series 6-24x50mm Tactical Elevation Knob for?

Long-range precision target shooters — dials drop corrections directly in metric units using precise 0.1 MRAD click adjustments across a single-turn 14.5 MRAD engraved scale on this riflescope elevation turret knob.
F-Class competitors — matches metric reticle values without conversion errors using this accessory dial's 0.1 MRAD per click increment and 14.5 MRAD total dial travel.
Long-range varmint hunters — enables rapid trajectory compensation on the fly via an exposed tactical elevation knob featuring 14.5 MRAD of laser-etched adjustment travel.

Less suitable for: Extreme long-range (ELR) shooting requiring dialled adjustments exceeding 14.5 MRAD in a single revolution; shooters needing greater single-turn travel require a multi-turn turret with mechanical revolution indicators or an optic featuring a 34mm maintube with expanded internal elevation capacity.
