What size scope tube and rail do the Sportsmatch ETO37 mounts fit?

25mm Extended Reach: Features a long front ring extension that delivers a 25mm offset, allowing you to increase or reduce eye relief on rifles with limited rail space or short receivers.
Recoil Management System: Includes an EASYFIT removable arrestor pin that drops directly into the receiver recess to prevent mount creep caused by bi-directional spring-piston airgun recoil or rimfire operation.
Double Clamp Design: Features four hex/Allen key bolts on each ring cap alongside double screws on the base clamp to ensure a high-friction, non-slip grip on your scope tube and rail.
High-Tensile Aluminium: CNC machined from premium aircraft-grade aluminium, ensuring structural integrity and precise alignment without adding excessive weight to your rifle setup.
Medium Profile Clearance: Designed to comfortably accommodate rifle scopes with an objective lens diameter of up to 44mm, or an outer objective case diameter of up to 59mm on standard flush-barrel rifles.

The Sportsmatch ETO37 mounts are precision-engineered for 30mm diameter rifle scope body tubes. They are designed to clamp securely onto standard 3/8-inch (9.5mm to 11.5mm) dovetail rails commonly found on modern air rifles and rimfire rifles.

How does the extended design of the ETO37 help with eye relief on my rifle?

The ETO37 features a long front ring extension that provides a 25mm (1 inch) offset, which can be oriented forward or backward to adjust your eye relief. This is especially useful on compact rimfires or bullpup air rifles with short receivers and limited rail space where standard ring placement leaves you straining for a full sight picture.

Will these mounts hold up against the harsh recoil of my spring-piston airgun?

Yes, these mounts feature an EASYFIT removable arrestor (recoil stop) pin that drops directly into the receiver's recess. This mechanical lock completely eliminates mount creep and sliding caused by the sharp, bi-directional recoil typical of high-powered airguns and rimfire cartridges used in Australian pest control.

Are there any Australian electrical or regulatory compliance certifications required for this product?

No, because the Sportsmatch ETO37 is a completely mechanical, non-powered hunting accessory containing zero electrical components, standard Australian electrical compliance criteria such as 240V compatibility, SAA certification, and RCM markings are not applicable.
