RAD! Testing The EC Tuner With EC Himself.

Published on September 23, 2021
Duration: 21:32

This video demonstrates the installation and initial testing of an EC Tuner brake by Eric Cortina himself. The process involves threading the brake onto the barrel, timing it using its flats, and securing it with a jam nut. The tuner screws are then tightened to a specific tension to prevent rotation. The video also touches on the design principles of the brake, including its port configuration for recoil reduction and comfort, and the tapered front for gas management.

Quick Summary

The EC Tuner brake is installed by threading it onto the barrel, timing it with its flats, and securing it with a jam nut. Three tension screws are then tightened to a specific point to prevent rotation, aiming for a tension similar to a scope's power ring. This process allows for fine-tuning barrel harmonics to improve rifle accuracy and reduce group sizes.

Frequently Asked Questions

How is the EC Tuner brake installed on a rifle?

Installation involves threading the brake onto the barrel, using its flats to time it precisely, and then securing it with a jam nut. The three tuner screws are then tightened to a specific tension to prevent rotation, typically by touching them to the barrel and adding a half turn.

What is the purpose of the EC Tuner brake's design?

The EC Tuner brake is designed to reduce recoil and improve rifle accuracy by fine-tuning barrel harmonics. Its four-port hybrid design manages gas efficiently, and the tapered front helps strip away residual gases for better bullet flight.

How does the EC Tuner brake achieve harmonic tuning?

The tuner allows for micro-adjustments that can fine-tune the barrel's harmonic vibrations. By finding the optimal setting, shooters can achieve tighter group sizes and maximize the precision potential of their rifle system.

What is the recommended tension for the EC Tuner screws?

The tuner screws are tension screws, not set screws. They should be tightened to a point where the tuner remains stationary when released, similar to the tension on a scope's power ring. A common method is to bring them to touch and then add half a turn.
