What does a barrel tuner do?

The MANAEL Barrel Tuner helps you manage and mitigate barrel harmonics and vibration to get the maximum potential out of your catridge and barrel. 

The MANAEL Barrel Tuner helps you find the optimum frequency specific to your catridge, load and barrel configuration. 

With every shot, your barrel undergoes vibrations and these harmonics affect the projectile as it leaves the barrel.

Moving the MANAEL Barrel Tuner back and forth on the barrel in micro adjustments will change the barrel harmonics to beter suit the projectile's requirements for a given load.

You can see the difference during the tuner install and set up; groups will narrow down as you get closer to the perfect frequency. 

Factory ammunition will often benefit from a tuner and hand loads have a potential to tighten group size. Please note quality and accurate handloads are required, this is not a replacement for load development process. Consult a reloading manual for correct and safe load data prior to use. 

Instructions for installing the MANAEL Barrel Tuner

Please read this guide completely before starting installation or use. Ensure your firearm is clear of all ammunition and is verified as unloaded and your firearm is in safe working condition prior to installation and use. Run a patch through your barrel and muzzle devices before use. Consult a reloading manual for correct and safe load data prior to use. You are responsible for confirming and complying with your state or territory firearms laws and regulations and where appropriate, advising your state or territory firearms authorities prior to any modification. Please refer to your local state or territory firearms/weapons act and regulations.

1. Identify the top centre point (12 o’clock) of the barrel using a texta or sticker

2. Remove your existing muzzle brake

3. Slide the MANAEL Barrel Tuner onto barrel with numbers facing towards the receiver. Keep going until the muzzle thread protrudes through the tuner. You will feel it "stop" in position (the tuner's internal lock will butt up against the face of the barrel where it steps down into the muzzle thread).

4. Replace your muzzle bake onto the barrel muzzle thread and secure. This will lock the MANAEL Barrel Tuner in place.

5. The MANAEL Barrel Tuner is now installed and ready for tuning.

6. To remove the tuner, reverse this process.

Instructions for use

1. Turn the tuner so number "0" is at the top centre point (12 o’clock position).

2. Fire two rounds at an identified target and note the group size.

3. Rotate the tuner by one number (this is the equivalent of 2 marked positions; a number and a mid-way line).

4. Fire another two rounds at a new target and note the group size.

5. Repeat this process and monitor the group sizes. As you are shooting at each tuner position, group sizes should start to shrink. This may take one or two complete revolutions of the tuner.

6. With each turn, the group size will continue to close up until a certain point. Then the groups will begin to open up again. This means you have found the optimum point and moved past it. 

7. Turn the tuner back to the previous position (where group sizes were at their tightest) and this is your optimum tuned position. Take note of the marked position on the tuner.

8. Lock the tuner into position by tightening the knurled ring lock nut (do not turn the tuner). Turn the nut until it is finger tight, so it won’t wriggle loose with vibrations. Your barrel is now tuned.

9. You will need to repeat this process if you change ammunition or loads.
