Detailed information

Product detailed description

EC Tuner X4 muzzle brake V2 M15x1 max cal .30

EC Tuner X4 muzzle brake V2 with M15x1 thread and maximum supported calibre .30 is a highly advanced muzzle brake with integratedbarrel tunerdesigned for shooters who want to not only reduce recoil, but especiallywork with the accuracy and consistency of your weapon. This model is the result of a collaboration between renowned designEric Cortina and expert productionGun Warrior, which gives rise to a cutting-edge solution for disciplines such as PRS, NRL, F-Class and hunting practice.


Impact brake and barrel tuner in one

EC Tuner X4 combines:

  • stretch brakewhich significantly reduces recoil and muzzle rise,

  • integrated barrel tunerwhich allows tuning of harmonic oscillations of the barrel.

This combination allows the shooter to improverepeatable accuracy of hits, reduce dispersion and optimize weapon performance without interfering with the barrel or changing the lab.


Video: Practical testing and EC Tuner Brake functions

For a visual idea of how the EC Tuner Brake works and how it behaves in real shooting, customers can watch a test video with practical demonstrations:

Version V2 - improved design

EC Tuner X4V2 is an updated and improved version of the original model. The main difference from the V1 version islarger and more massive tuner nut:

  • faster and more efficient debugging,

  • higher influence on the harmonic oscillations of the barrel,

  • better feel when adjusting,

  • the possibility to reach the optimum tuning point faster.

The V1 version uses a slimmer nut tuner that is feature efficient, but the V2 shiftscomfort, stability and tuning speed to a significantly higher level.


What are harmonic oscillations mainly and why they affect accuracy

When fired, the barrel is tuned as an elastic system, which vibrates due to the pressure of the gases and the movement of the projectile. These vibrations, calledharmonic oscillations, affect the moment the bullet leaves the muzzle - and thus the resulting accuracy.

If the projectile leaves the barrel in an unstable phase of the rhythm, the resulting dispersion of hits is greater. If it leaves the barrel at a quieter, repeatable point of vibration, accuracy is greatly improved. The EC Tuner allows you to change the weight and position at the muzzle to adjust the frequency and phase of these oscillations to the ammunition and gun configuration.
