How do I tune my rifle using a MANAEL Barrel Tuner?

Important Precautions:

  • Safety First: Before installation, ensure your firearm is clear of all ammunition and verified as unloaded. Confirm that your firearm is in safe working condition.
  • Legal Compliance: You are responsible for confirming and complying with your state or territory firearms laws and regulations. Consult your local authorities before any modification.

Note: Instructions for installing the MANAEL Barrel Tuner can be found here

Preparing for the Tuning Process

  1. Read Instructions Twice: Familiarize yourself with the instructions by reading them thoroughly twice
  2. Prepare your targets: The MANAEL Barrel Tuner requires live-fire at a target where you can easily see your groups, such as paper targets, at a known distance.
    • Testing can be done at 100m or beyond, as long as you can reliably shoot on paper at that distance.
    • Inspect the target regularly, and be patient—it may take several rounds of testing at different settings to find the optimal position for your rifle and ammunition.
    • Use a consistent batch of ammunition/loads for the tuning/testing process.
    • Group sizes may change in “waves.” Be patient and work through the wave, going “past” the perfect tuning spot and back again. This may take multiple full rotations of the tuner body.

Tuning Guide for MANAEL Barrel Tuner

  1. Mark your home position:
    • This step is optional, but enables rapid, repeatable alignment. It provides a clean alignment mark for the tuner.
    • Place two strips of tape on your barrel lengthways, inline with the bullet travel, about 0.5mm to 1mm apart.
    • Paint between the tape with nail polish or a paint marker, wait to dry, then peel the tape off.
  2. Set Tuner in home position
    • Place MANAEL Barrel Tuner in the starting position with number “0” at the top center point (12 o’clock position) or inline with the painted mark.

  3. Identify optimum Barrel Tuner position:
    • When safe to do so, fire 2 or 3 rounds at an identified target and note the group size.
    • Rotate the tuner by one number (equivalent to 2 marked positions) and fire another two rounds at a new target, noting the group size.
    • Repeat this process, monitoring group sizes.
    • As you shoot at each tuner number/position, group sizes will start to change, eventually shrinking. This may take one or two complete tuner revolutions.
    • With each turn, the group size will continue to close up until a certain point. Then, groups may open up again, indicating you’ve moved past the optimum point.
    • Turn the tuner back to the previous position (where group sizes were tightest)—this is your optimum tuned position. Take note of the marked position on the tuner using the timing marks on the Tuner body.

  4. Set & Lock Tuner at Optimum Position
    • Once your MANAEL Barre Tuner is turned to the position which gives the tightest group sizes, it needs to be secured in position.
    • Lock the tuner into position by tightening the knurled ring lock nut. Do not turn the Tuner body. Turn the lock nut until it is pinch-tight to prevent it from loosening.

  1. Before removing the MANAEL Barrel Tuner
    • If you plan to remove the MANAEL Barrel Tuner, make a note of the numbered position before removal.
    • When reinstalling, start the tuning process from the previously numbered position to expedite finding that sweet spot.

Note: You will need to repeat the tuning process if you change ammunition or loads, or if the MANAEL Barrel Tuner is placed on a different rifle or barrel.

How do I install a MANAEL Bloop Tuner (Barrel Tuner & Bloop Tube)?

Important Precautions:

  • Safety First: Before installation, ensure your firearm is clear of all ammunition and verified as unloaded. Confirm that your firearm is in safe working condition.
  • Legal Compliance: You are responsible for confirming and complying with your state or territory firearms laws and regulations. Consult your local authorities before any modification.

Installation Guide for MANAEL Bloop Tube & Barrel Tuner (Bloop Tuner)

Pre-Installation:

  • Read Instructions Twice: Familiarize yourself with the instructions by reading them thoroughly twice
  • Prepare all parts: You will need a MANAEL Bloop Tube and a compatible size MANAEL Barrel Tuner.

Note: Photos in this guide may display different models of the MANAEL Ultralite Bloop Tuner, including the Ultralite model. The installation process remains the same for all models.

Installing the MANAEL Bloop Tuner (Bloop Tube & Barrel Tuner)

  1. Disassemble the MANAEL Barrel Tuner
  • Unscrew the MANAEL Barrel Tuner’s internal thread cup, this will free Tuner components (tuner body, lock ring, and o-ring).
  • Take note of where the o-ring sits against the Tuner face
  • Set aside the o-ring, knurled lock ring and tuner body (which is the large weighted piece with the MANAEL logo and timing identifier marks).
  • Safely store the internal thread cup (and thread adaptor if required) for future use. These are not needed when using the MANAEL Tuner on a MANAEL Bloop Tube.
  • Some models of MANAEL Bloop Tube have a thread protector. This will need to be removed and set aside.

2. Attach MANAEL Barrel Tuner Weighted Body to MANAEL Bloop Tube

  • Slide the MANAEL Barrel Tuner Weighted Body onto the smaller end of the MANAEL Bloop Tube (the end without external threads).
  • Orient the flat edge towards the external thread (front end) of the Bloop Tube and the tapered edge towards the smaller part of the tube (back end).
  • Push the Tuner Weighted Body tuner to the front of the Bloop Tube, screwing it onto the thread, leaving about 10mm of threads exposed.

3. Place O-ring and Locknut

  • Put the o-ring over the MANAEL Bloop Tube external thread. Position the o-ring against the Tuner’s face (same position it was in when disassembling the Tuner).
  • Screw the Tuner Lockring onto the exposed thread of the Bloop Tube.

4. Install to Your Gun

  • Ensure the end with Tuner is furthest from the rifle muzzle.
  • Screw the tube end onto the rifle muzzle thread using the tube’s internal thread.

5. Final Checks

  • Perform necessary safety checks.
  • Your MANAEL Bloop Tuner (Bloop Tube + Barrel Tuner) is now installed & ready for the tuning process, allowing you to optimize your rifle’s performance effortlessly.
