The Miracle of 5.8 Centimeters (Perfect for Pistol Grip):
The main problem with HPA systems is where to hide the electronic control unit (FCU) and its battery. Often you are forced to pull the cables to the stock tube. EMG solves this problem at the root: this cylindrical micro-battery measures just 58 x 17 mm! These Lilliputian dimensions allow you to comfortably stow both the battery and the FCU board inside the grip (motor grip) of your M4, leaving the stock completely free.
Lithium-Ion Safety and JST Connection:
HPA control units are lethal for classic LiPos, because they consume a little current even at rest and tend to make them swell. With the Li-Ion (Lithium Ion) technology of this EMG, the swelling problem is literally erased: zero memory effect and extreme longevity. Its 350mAh (2.59Wh) guarantees the energy needed for thousands of firing cycles, and thanks to the native red JST connection, you connect it to your Polarstar or Wolverine without any need for annoying adapters.
Main Advantages
- Micro Size (5.8 cm): The absolute minimum size, ideal for hiding it in the rifle grip.
- Immortal (Li-Ion Technology): Forget swollen batteries. Lithium Ions guarantee total stability and safety.
- Direct JST Connector: Ready to use to natively power Polarstar, Wolverine and compatible FCUs.
- EMG Efficiency: High-density cells to never run out of energy during matches.

Pro Tips
The Queen of Pistol Grips: Compared to longer models, this EMG is the must-have choice if you want to keep your setup super-clean and hide all the HPA "brain" in the grip, without having to pass the wires through the tube. But be careful: if you close the grip cap, make sure not to pinch the very delicate wires of the JST connector!
The Electronic "Vampire" (Always disconnect it!): Even if it is a Li-Ion and does not swell, physics is not an opinion: if you leave it attached to the FCU for a week, the control unit will "suck" away all the energy and the battery will drop to 0 Volts, damaging itself irreparably. Always be careful to disconnect the red connector as soon as you put the rifle back in the bag!
Are you looking for compressed air perfection? The Workshop is waiting for you! A poorly assembled and aligned HPA system shoots worse than a spring rifle. To get that tight, silent and lethal shot you dream of, you need millimeter precision and expertise. Trust M Tactical! Go to the "Custom Works" section: our technicians will convert your replica by assembling the HPA mechanics and the control unit to perfection.
