Will the Sightron SI-74002 tactical elevation knob fit my Sightron SIII 10-50x60 riflescope?

No, this specific knob model (SI-74002) is engineered exclusively for Sightron SIII 8-32x56 models and will not fit 6-24x, 10-50x, or other non-8-32x tactical variants. For 10-50x scopes requiring a tactical elevation upgrade, a different part such as the SI-74001 is typically required. Always verify your specific scope magnification and click value before purchasing.

Is this elevation knob compatible with Sightron scopes that use 1/8 MOA click values?

No, this tactical elevation knob is strictly designed for scopes utilising 1/4 MOA per click mechanisms. The manufacturer explicitly states it will not fit Sightron target-turret scopes that rely on finer 1/8 MOA adjustments. Using this knob on an 1/8 MOA system will result in incorrect tracking and incorrect laser-etched scale readings.

What are the key adjustment specifications of the SI-74002 knob for long-range target shooting?

The SI-74002 provides 1/4 MOA adjustment per click with a white laser-etched scale reading up to 29 MOA of elevation adjustment per full revolution. Built with deep knurling for positive grip and an extra-long shaft to handle heavy torque loads, it is rated to support elevation tracking for target engagements extending past 1,000 metres. It is fully resettable to zero and capable of enduring heavy centre-fire recoil in harsh Australian outback conditions.

What companion windage turret pairs with this elevation knob?

The Sightron SI-74002 elevation knob is specifically designed to pair directly with the companion Tactical Windage Turret part number #75002. Together, they replace standard capped turrets on compatible SIII 8-32x56 riflescopes to provide high-visibility, fast-dialling tactical controls for F-Class and long-range benchrest competitors. As a passive mechanical component, electrical compliance and certifications such as SAA or RCM do not apply.

Tactical Elevation Knob - Sightron SI-74002

The Sightron SIII Series 8-32x56mm Tactical Elevation Knob (model SI-74002) is an aftermarket replacement turret dial engineered specifically for selected Sightron SIII 8-32x56 riflescopes. Built to replace low-profile capped turrets, this passive mechanical component upgrades the optic to an exposed, positive-turn tactical dial for rapid, repeat elevation tracking across target distances up to and exceeding 1,000 metres. It features deep knurling for positive hand grip, an extra-long shaft engineered to handle heavy torque loads, and a zero-reset mechanism. Finished in matte black with laser-etched white scale markings, it is rated to withstand recoil on heavy magnum centre-fire rifles.

Who is the Sightron Siii Series 8-32x56mm Tactical Elevation Knob 29 Moa for?

Long-range precision shooters using Sightron SIII 8-32x56 optics — delivers exposed, high-visibility indexing calibrated specifically for 1/4 MOA clicks, allowing fast ballistic compensations past 1,000 metres without removing turret caps.
F-Class and benchrest competitors — provides 29 MOA of elevation adjustment per single revolution on this riflescope elevation turret knob to eliminate multi-turn dial confusion during rapid course-of-fire adjustments.

Less suitable for: Precision target shooters using Sightron scopes configured with 1/8 MOA click values or optics outside the 8-32x platform (such as 6-24x or 10-50x models); these setups require dedicated 1/8 MOA target dials or model-specific replacement tactical knobs designed for different turret gear systems.
