Frequently Asked Questions

What is the EC Tuner and what is its purpose?

The EC Tuner, designed by Erik Cortina, is a precision rifle accessory for .22LR calibers. Its purpose is to fine-tune barrel harmonics by adjusting tension, which helps achieve smaller group sizes and improve overall rifle accuracy.

How is the EC Tuner installed on a .22LR rifle?

Installation involves threading an adapter (bloop tube) with 1/2-28 threading onto the barrel using an armorer's wrench. The external tuner then threads onto this adapter.

What tools are needed to install and set the EC Tuner?

You will need a standard armorer's wrench to install the adapter and a 3/32 hex wrench to tighten the set screws on the tuner, which are used to apply tension.

How do you tune the EC Tuner for optimal accuracy?

Tuning involves adjusting the tuner by hand and shooting two-shot groups at different settings. The goal is to find the 'sweet spot' where the smallest groups are consistently achieved.
