EC Tuner BEAST 35 M18x1 is an extremely robust muzzle brake with integrated barrel tuner, designed for large calibre and ELR shooting. It is based on a licensed conceptEric Cortina and is manufactured byGun Warrior. Massive construction and very large ports allow efficient gas management even for extreme energy charges. The brake significantly reduces recoil and barrel stroke. Integrated tuner allows tuning of barrel harmonic oscillations for better hit consistency. The BEAST 35 is designed for .300 Winchester Magnum and larger cartridges. It is the ideal choice for extreme long range shooting and King of 1 Mile and King of 2 Miles competitions. Suitable for long and heavy barrels used in ELR disciplines. The robustness and weight are deliberately designed for maximum stability and gun control.

Detailed information

Product detailed description

EC Tuner BEAST 35 muzzle brake M18x1 max cal .338+

EC Tuner BEAST 35 with M18x1 thread isextremely robust stretch brake with integrated barrel tuner, designed forthe most powerful calibers and extreme long range shooting (ELR). As the name suggests,BEAST 35 is a real monster - The massive construction, extremely large ports and high weight are purposefully designed to work with huge volumes of gases that produce large-calibre charges.

This model is based on a proven and extremely effective conceptEC Tuner Brake, whose author isEric Cortina. CompanyGun Warrior took this foundation even further and added the so-called."WARRIOR muscle" - an extremely robust design for the most demanding applications.

Impact brake and barrel tuner in one - without compromise

The EC Tuner BEAST 35 combines two key functions in one massive body:

  • highly effectivestretch brakewhich drastically reduces recoil and muzzle rise even with extremely powerful bullets
  • integrated barrel tuner
  • , allowing fine tuning of harmonic oscillations of the barrel

This combination greatly facilitatesdebugging labs, improvesrepeatable accuracy and allows the shooter to better control the weapon when firing. For .300 WM and larger calibers, this is not a convenience accessory, but anecessityif the shooter is to achieve consistent results over the long term.

BEAST 35 - designed for extreme long range

ModelBEAST 35 is specifically designed for:

  • extreme long range shooting
  • contestsKing of 1 Mile aKing of 2 Miles
  • large-calibre, high-pressure, high-energy cartridges
  • long and heavy barrels used in ELR disciplines

The manufacturer states with exaggeration that the ports are so large "you could almost park a car in them" - and it is this massiveness that is the key to effective gas and recoil management in extreme calibers.

What are harmonic oscillations and why they are essential in large calibre calibers

When the barrel is fired, it vibrates due to the pressure of the gases and the movement of the projectile. Theseharmonic oscillations of the barrel have a direct effect on accuracy because they determine the position of the muzzle as the bullet leaves the barrel.

With large caliber cartridges such as .300 WM, .338 Lapua Magnum and larger, these vibrations are more pronounced and harder to control. If the projectile leaves the barrel in the unstable phase of the oscillation, significant vertical and horizontal dispersion occurs.

The EC Tuner BEAST 35 allows the mass and position of the tuner to change the frequency and phase of the oscillations so that the projectile leaves the barrel atrepeatable and stable vibration point. The result isless dispersion, better vertical consistency and more certainty of hits at extreme distances.

Eric Cortina - author of the EC Tuner concept

Eric Cortina is a renowned American shooter, designer and trainer in the field of precision and long range shooting. He has achieved top results in the F-Class disciplines and has long been involved in ballistics, barrel tuning and gun behavior. The EC Tuner concept originated as apractical solutions developed directly from competition practicenot as a theoretical experiment.

It is thanks to this approach that its design todaylicensed and used by manufacturers focused on the absolute top in long range and ELR shooting.
