IT IS STRONGLY ADVISED TO READ THIS ENTIRE MANUAL 

FAILURE TO ADHERE TO THESE PROCEDURES COULD RESULT IN 

PERSONAL INJURY OR CATASTROPHIC DAMAGE TO THE EMG-02 

 

 

 

1. Introduction 

 

The Arcflash Labs EMG-02 (Electro-Magnetic Gun – 02) is a 10 stage medium voltage capacitor 

augmented fully automatic coilgun. 
 

It features 10 stages controlled by a nanosecond-precise microcontroller which allows for firing up 

to 8 rounds per second full auto, or up to 13 rounds per second in a three round burst mode. The 
nominal speed of projectiles is 70-75 m/s (230-250 fps). 

 
The EMG-02 is configured to fire steel projectiles (dowel pins) between the diameter range of 0.25-

0.3125” and between 0.75-0.875” in length.  Arcflash Labs recommends the use of 2575, 51634 or 
51678 Magnetic Armatures (sold separately) but ordinary steel dowel pins, ¼” drill bits or even ¼-5/16” 
round stock cut to proper length should fire from the EMG-02.   

 
The EMG-02 is shipped standard with the MG15A constant-pressure magazine which can hold up to 

15 rounds single stacked.  It is also compatible with the MG15XL magazine intended for the longer 
5/16x7/8” armatures which can deliver up to 20J muzzle energy on target. The EMG-02 is also 
backward compatible with the SG18 and the MG18 magazines of the SGP-35 and EMG-02.  The gun is 
also shipped standard with a 60v Max Lithium Ion (drill) battery and associated charger. It is also cross-
compatible with certain yellow 60v cordless drill batteries. The included battery can provide power for 
over 300 shots before needing to recharge.  The rate of fire of the EMG-02 (up to 8 rounds/sec) is 
limited by the discharge rate of the lithium ion battery.  

 
 
 
 

- TREAT THE EMG-02 AS YOU WOULD A FIREARM. NEVER POINT IT AT ANYTHING OR ANYONE 
YOU DO NOT INTEND TO DESTROY. 
- ALWAYS ENSURE THE POWER SWITCH IS SET TO THE OFF POSITION BEFORE INSERTING THE FUSE 
OR BATTERY.   
- NEVER STICK FINGERS OR ANY FOREIGN MATERIAL INTO THE VENT HOLES. 
- DO NOT FIRE ROUNDS SHORTER THAN 0.75” IN LENGTH OR SMALLER THAN 0.25” IN DIAMETER
