Impulse Gun Barrels
The Impulse Gun Barrels (IGB) version uses a somewhat different approach. Rather than a complete new upper, the IGB simply
uses a carbine length barrel. Due to a change in mass associated with the longer barrel the IGB kit uses a special system
to ensure proper cycling of the slide. The company describes it as follows:
The IMPULSE System operates with employing powder gases, supplied through the ports located in the barrel, which transfer
their energy onto the slide of the gun via gas collector and energy carrier. This process balances out mass-irregularities
and permits reliable functioning also when using heavier or longer barrels or sleeves.
