What is the adjustable weight of pull range for the Rifle Basix CZ-52 trigger?

The Rifle Basix CZ-52 replacement trigger is adjustable between 10 oz. and 2.5 lbs (approximately 283 g to 1.13 kg). It provides a crisp single-stage break designed to eliminate the heavy pull and creep inherent in factory rimfire triggers for improved precision.

Is the Rifle Basix CZ-52 compatible with CZ centerfire rifles or the CZ 453 model?

No, this trigger is built exclusively for CZ rimfire bolt-action rifles like the CZ 452 and CZ 455. It is not compatible with CZ centerfire platforms or CZ 453 models equipped with factory single-set triggers, which require a dedicated unit such as the Rifle Basix CZ-527.

Does this aftermarket trigger require any electrical certifications or 240V mains power in Australia?

No, the CZ-52 is a purely mechanical firearm component and does not feature any electrical parts. Therefore, electrical compliance requirements such as 240V mains power, Australian plugs, and SAA or RCM certifications do not apply.

What is included in the installation kit for the Rifle Basix CZ-52?

The complete kit includes the single-stage aftermarket replacement trigger unit, installation hardware such as a replacement pivot pin, sear release pin, pull-weight spring, and an adjustment hex wrench. Note that installation requires minor permanent fitting on the rifle by grinding the factory bolt-stop release pin flush.

CZ 452 Trigger Upgrade - Rifle Basix CZ-52

It integrates directly with the factory bolt-mounted safety and is designed for rimfire calibres including .22 LR, .22 WMR, and .17 HMR.
