LATEST UPDATE

Thank you for purchasing the MILSIG M79 blaster.
Like any blaster, it is important that safety is at the forefront of your mind at all times when using this product. Never operate the M79 without ASTM- compliant goggles or aim at anyone that is not wearing proper goggles intended for the game of foam dart.
The MILSIG M79 blaster is an advanced system that is suitable for all levels of play and will provide years of service if the following steps are meticulously followed.

1. Before airing up, place 3 drops of MILSIG-approved oil into the ASA(Air Source Adapter).
2. Screw in your air source into the rear ASA(the Air System must have an output pressure of 800 psi for the M79 to function properly)
3. “Dry” Cycle the M79 without paint to evenly distribute oil into the unit.

NOTE
The performance of the M79 series HEAT CORE is the same. Please refer to P. 9, SPECIFICATIONS to know the different specs between M79 and M79A2

OPERATION INSTRUCTIONS

INSTRUCTIONS

1. MILSIG M79 series is powered by HPA. Check the air pressure via a pressure gauge.
2. Fill the MILSIG MAGic CORE HPA tank to 3000 psi before using the M79.
3. M79 cannot function if the air pressure is lower than 800 psi. Always keep the pressure of the air tank over 800 psi when using.
4. Be sure to switch the selector switch to SAFTY mode every time when turning ON/OFF the HPA tank. Otherwise, the HEAT CORE may be activated unexpectedly.
5. Turn on the switch of the MILSIG MAGic CORE HPA tank to activate the HEAT CORE before using the M79 blaster.
6. Turn off the switch of the MILSIG MAGic CORE HPA tank to deactivate the HEAT CORE when you want to stop playing.
7. Before adjusting the air velocity with the HEAT CORE regulator, please switch off MILSIG MAGic CORE HPA tank first.
8. To use M79A2, connect the HPA tank and EXTERNAL HPA TANK CONNECTOR via the HPA tube.
9. Another way to use M79A2 is: Remove the EXTERNAL HPA TANK CONNECTOR, and twist in the HPA tank to ASA as P.7 showed.

WARNINGS

1. Always keep the pressure of the MILSIG MAGic CORE HPA tank below 3000 psi for safety concerns. Otherwise, the safety seal of the HPA tank will activate.
2. The HEAT CORE may activate unexpectedly even if the selector switch stays in SAFTY if the user chooses to use a non-MILSIG HPA tank without the HPA tank ON/OFF switch.
3. Do not insert any body part or any other object into Bolt Action Window before switching the selector switch to SAFTY mode.
4. Do not leave the CO2 cartridge in the CO2 stock for more than 3 hours.

BEST PERFORMANCE

1. MILSIG recommends players set at least 200 FPS velocity for a 20m level shot; at least 300 FPS velocity for a 30m level shot.
   This test result is based on using an MA foam dart.

2. For best accuracy, MILSIG suggests user install external SCAR. Otherwise, the user can choose to tie 6 strings on the SCAR integrity barrel to increase accuracy even if the velocity may decrease a little bit.

3. The performance of velocity, accuracy, and maximum range of MILSIG M79 HPA FOAM DART BLASTER will be affected by the quality and SPEC of the foam darts under the same air pressure setting.
   MILSIG recommends using the MILSIG & AACS foam dart (MA dart) to perform the best performance of the M79 series.

MILSIG &AACS foam dart (MA dart)
Weight : 1 ± 0.1 g
Dart head Hardness: 24 ± 2 Hs Foam material: High-density foam Length: 37 ± 0.15 mm
Diameter : 13 ± 0.1 mm
Dart head material: Thermoplastic rubbers (TPR)

FULL-AUTO FUNCTION

1. Set up the HEAT CORE regulator and make sure the air velocity is higher than 240 FPS.
2. The air pressure supply must be higher than 1000 psi to ensure the FULL-AUTO function is fully operational.
3. 2-stage trigger functioning when using FULL-AUTO mode. Pull the trigger a little bit for a single shot; pull the trigger to the end for the FULL-AUTO shot.
4. CO2 power can’t activate the FULL-AUTO function.

VELOCITY ADJUSTMENT

ADJUST THE VELOCITY with HEAT CORE REGULATOR

1. Before start adjusting the air velocity with the HEAT CORE regulator, please switch off the MILSIG MAGic CORE BLACK HPA tank first.
2. Make sure the M79 blaster is on SAFTY mode by checking the selector switch.
3. Increase velocity by turning the velocity adjustment set screw clockwise, or decrease velocity by turning counterclockwise. Fire several shots to test the new velocity setting before further adjustments are made.
4. The range between the maximum velocity and the minimum velocity of the M79 blaster HEAT CORE mechanical system is around 140±10% FPS which the test is based on MA foam dart.
   

FEATURE OF HEAT CORE REGULATOR

1. HEAT CORE REGULATOR is sensitive. 1-degree change of the REGULATOR screw leads to around 2 FPS changes. This test result is based on using an MA foam dart.
2. Rotate the regulator clockwise to the end to launch the foam dart at maximum velocity.
3. Rotating the regulator counterclockwise to the end will cut off the HPA supply.
4. There is a minimum working air pressure for HEAT CORE.
   Rotate the regulator in counterclockwise too much will result in insufficient air supply.
   Rotate the regulator in clockwise to increase the air supply if the HEAT CORE work is abnormal which cause by insufficient air supply if the situation above happens.

NOTE
Make sure the air pressure of the blaster is stable after every velocity adjustment by firing multiple shots through a chronograph. It may take several shots for the velocity change to happen. M79 blaster may fire one shot when it is aired up.
This is due to the bolt being left in its position from the previous use. The bolt will reset itself and it is not a sign of malfunction.

STOCK INSTALLATION

Magic CORE ADJUSTMENT

ADJUST THE DIRECTION OF PRESSURE GAUGE ON MAGic CORE HPA tank

1. Be sure to empty the air tank before adjusting the place of the pressure gauge.
2. Install the HPA tank into the ASA.
3. Loosen all three of the adjustment screws.
4. Make the pressure gauge of the HPA tank face the top, aligned and paralleled to the charging handle by rotation.
5. Tighten all the adjustment screws.
