Redline Airsoft N7 Gen2 Electro-Pneumatic HPA Conversion Kit for Gear Boxes

The Redline N7 Gen2 is a Patent Pending HPA drop in cylinder replacement system. The very first single solenoid, true closed bolt HPA engine.

The N7 Gen-2 uses a single solenoid, has a forward biased nozzle and fires from a true closed bolt.

Due to its true closed bolt design and air balanced nozzle return, the N7 Gen-2 is much more consistent in seating the BB in the bucking from shot to shot when compared to a typical open bolt HPA engine. The result is more consistent shot to shot velocity, tighter groupings and greater accuracy at range when compared to open bolt HPA engines.

Just like the original N7 the N7 Gen-2 uses a mechanically sealed, dump chamber. Rather than relying on solenoid dwell to control the volume of air used to propel the BB, the N7 Gen-2 fills an internal air chamber at the pressure set by the user’s external supply regulator.

 When fired, this air chamber is mechanically sealed off from the supply and the chambers contents is released down the barrel to propel the BB. This feature contributes to the N7 Gen-2’s excellent shot to shot consistency, with no air wasted due to improper dwell settings.

The N7 Gen-2 is super simple to set up. Since there is no poppet dwell to tune you simply set your supply regulators output pressure to match the Joules required and you are good to go. The proper amount of air needed for each shot, regardless of BB weight, barrel length or any other factor is all that is released.

The FCU is programmable for:

 Nozzle Dwell
Semi Auto Max Rate of Fire
Full Auto / Burst Mode
Full Auto Rate of Fire
Anti Stiction Pulse
Selector position
