Will the Hawke Model 62191 thread adaptor fit my post-2015 Hawke Sidewinder 42mm riflescope?

No, this adaptor is exclusively designed for legacy pre-2015 Hawke Sidewinder scopes. Post-2015 models feature native threading on the objective bell and do not require or accept this adaptor ring.

Can I use this 42mm adaptor on other Hawke scope lines like Vantage or Airmax?

No, the Model 62191 is engineered specifically for the proprietary thread pitch and diameter of pre-2015 42mm Sidewinder objectives. It is incompatible with Vantage, Airmax, or Frontier scopes, as well as different objective sizes such as 50mm or 56mm models.

What modern accessories does this thread adaptor allow me to attach to my legacy scope?

Once threaded onto the 42mm objective bell, this adaptor allows your legacy Sidewinder to accept modern Hawke metal flip-up lens covers and screw-in honeycomb sunshades. This lets you upgrade older optics without replacing the entire riflescope.

Does this passive optical accessory require any electrical safety compliance or SAA/RCM certification for use in Australia?

No, the Hawke 62191 is a purely passive mechanical accessory made from machined anodised aluminium with no electrical components. Therefore, Australian electrical standards, SAA/RCM approvals, and 240V ratings are completely inapplicable.

Thread Adaptor - Hawke 62191

The Hawke Sidewinder Thread Adaptor (Pre-2015) 42mm Objective (Model 62191) is a precision-machined, anodised aluminium optical accessory designed to retrofit legacy riflescopes. Before 2015, Hawke Sidewinder scopes featured older proprietary screw-in threading at the objective bell. This passive mechanical ring threads directly into pre-2015 42mm objective bells, converting the interface to match modern post-2015 female thread standards. This conversion allows shooters to mount contemporary Hawke metal flip-up lens covers and honeycomb sunshades (killflashes) without replacing their existing optic.

Key Features

Interface Conversion: Adapts pre-2015 proprietary Hawke objective threading to post-2015 accessory standards.
Modern Accessory Integration: Enables older optics to accept current metal flip-up lens covers and honeycomb killflash sunshades.
Durable Construction: Made from machined, anodised metal designed to maintain all-calibre recoil and shockproof ratings on the Sidewinder platform.
Passive Design: Fully mechanical screw-in component requiring no external power or electrical interfaces.

Specifications

Material: Machined anodised metal / aluminium
Objective Bell Compatibility: 42mm

Who is the Hawke Sidewinder 42mm Thread Adaptor for?

Owners of pre-2015 Hawke Sidewinder riflescopes — requires a dedicated riflescope objective thread adaptor matching the older 42mm objective bell interface to install modern protective metal flip-up covers.
Hunters and pest controllers upgrading legacy optics — relies on the 42mm objective thread conversion to attach anti-glare honeycomb sunshades directly to pre-2015 Sidewinder platforms in high-glare field environments.

Less suitable for: Post-2015 Hawke Sidewinder scopes that already feature native female threading, optics with 50mm or 56mm objective bells that require larger dedicated thread adaptors, or non-Sidewinder models (such as Airmax, Vantage, or Frontier) that use incompatible thread pitches.
