The Sportsmatch Problox Crosman Dovetail 11mm Adapter (Model: PROBLOX) is a British-manufactured, precision-engineered mounting accessory designed to resolve the optical mounting limitations of popular Crosman airguns. Because many classic Crosman air rifles and air pistols are manufactured without integrated receiver rails, mounting an optic out of the box is not possible. The Sportsmatch Problox system solves this by clamping directly and securely around the outer diameter of the gun's barrel, providing a stable, parallel 11mm dovetail platform for mounting rifle scopes, red dot sights, or laser sights.

Key Features:

• Dual-Block Design: Supplied as a two-piece set, allowing users to position each 20mm block along the barrel at the precise distance required to match their chosen optic's mounting rings.
• High-Precision Machining: Manufactured in the United Kingdom to strict tolerances, ensuring a tight clamp that prevents rotation or slipping under firing vibration without damaging the barrel.
• Standard Output Rail: Converts the barrel profile into a standard 11mm dovetail rail, making it compatible with a wide range of standard airgun scope rings.
• Simple Installation: Includes the necessary Allen key for a straightforward, bolt-on installation with no gunsmithing required.
• Passive Mechanical Construction: This product contains no electrical wiring, batteries, or circuitry. Consequently, Australian electrical safety standards, SAA approvals, and Regulatory Compliance Mark (RCM) certifications do not apply.

Who It Is For:

The Sportsmatch Problox is designed for Australian airgun enthusiasts, target shooters, and pest controllers who want to upgrade their Crosman air pistols or air rifles with optical sights. Whether you are using a Crosman 1377 for backyard plinking or a Crosman 2250 Ratcatcher for selective pest control, this adapter provides the stable platform required for consistent accuracy. While mechanical scope mounts are generally unrestricted retail items across Australia, customers should remain aware of their local state and territory regulations regarding licensing and registration for Category A air rifles and restricted air pistols.
