Tuner EC (Erik Cortina) for Warrior 1/2x20 max .22 cal

WARRIOR Rimfire Barrel Tuner .22 - version without suppressor thread

The WARRIOR Rimfire Barrel Tuner is a precision tuning device for .22 caliber small caliber rifles, designed for shooters who want to maximize accuracy and consistency when using factory ammunition. This is a long awaited product that brings the proven principles of the EC Tuner concept from large caliber and competition shooting to the world of rimfire guns.

This model is based on an extremely efficient tuning solution designed by Eric Cortina, whose design is based on a deep understanding of barrel behavior when fired. Manufactured by Gun Warrior, a world-renowned brand specializing in custom guns, chassis systems and precision components used in competitive shooting.

Rimfire tuner as the key to accuracy with factory ammunition

Unlike large-caliber rifles, where accuracy can be significantly affected by reloading, shooters in the .22 LR caliber rely primarily on the selection of factory ammunition. However, even with quality ammunition, there are differences in barrel behaviour that directly affect the dispersion of hits.

WARRIOR Rimfire Barrel Tuner allows:

• fine tuning of harmonic oscillations of the barrel

• reduction of vertical dispersion

• improving the repeatability of interventions

• optimization of barrel behaviour for a specific type of ammunition

Thanks to the mechanical shift of the mass at the muzzle, a noticeable improvement in accuracy can be achieved without any interference with the weapon and without the need to change the ammunition.

Harmonic oscillations mainly in small arms

Even with small calibre rifles, harmonic oscillations of the barrel occur during firing. These vibrations affect the position of the muzzle as the bullet leaves the barrel and thus have a direct effect on the resulting accuracy.

In the .22 LR caliber, the differences are often very subtle, but at the same time extremely sensitive. A small change in frequency or phase of the oscillation can mean the difference between an average group and a truly superior result. A barrel tuner allows you to influence these oscillations and tune the barrel to specific ammunition, greatly improving the consistency of hits, especially at longer ranges.

Non-threaded version - simplicity and clean function

This variant of the WARRIOR Rimfire Tuner is the version without the through-thread for the shock absorber. It is a pure barrel tuner whose only purpose is precision tuning.

This configuration is ideal for shooters who:

• does not fire with a silencer

• they want the simplest and lightest possible solution

• prefer a pure tuning function without additional components

• shoots sport or competitively on open ranges

Thanks to its compact dimensions and balanced weight, the tuner does not negatively affect the handling of the weapon.

EC Tuner philosophy by Eric Cortina

Eric Cortina is a respected American shooter, designer and trainer, known for his success in the F-Class disciplines and his long-standing work in accuracy and ballistics. The EC Tuner concept was developed as a practical solution from competition practice, not as a theoretical experiment.

The WARRIOR Rimfire Tuner brings this philosophy to rimfire shooting, giving smallbore shooters a tool that was previously only common in high-end competition rifles.
