Redline N7 HPA GEN2 Milsim Engine (Mechanical)

Redline N7 HPA GEN2 Milsim Engine - Fully Mechanical.  The newest mechanical pneumatic HPA airsoft engine from Redline.  Comes in V2 (M4) or V3 (AK nozzle) style.  Can be customized with different aftermarket nozzles for specific gun types.  No battery needed, as it doesn't require electricity.  Fully mechanical and runs solely on air power.

Manufacturer specs:

The Redline N7 Milsim Gen-2 is a Patent Pending HPA drop in cylinder replacement system. It is an updated version of our legendary N7 Milsim, the very first fully mechanical, true closed bolt HPA engine.

Like the original N7 Milsim, the N7 Milsim Gen-2 has a forward biased nozzle, fires from a true closed bolt and has fully mechanical operation. No battery or FCU needed!

The N7 Milsim Gen-2 also comes with our new Enhanced Trigger Valve. The Enhanced Trigger Valve features a short crisp trigger pull, a "break" at the release point and a reset action on the release.  There is no cross bleed of air when the trigger is pulled slowly, so no matter how you pull the trigger, you get consistent trigger action.

The most noticeable change from the original N7 is the elimination of the external airline to the nozzle. We have also updated the internal components and slightly reduced the size of the air chamber. Functionally however, it is identical to the original N7 Milsim. Meaning you get the same great performance and easy setup that the original N7 engines were known for.

Due to its true closed bolt design and air balanced nozzle return, the N7 Milsim 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 Milsim 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 Milsim Gen-2’s excellent shot to shot consistency.

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.

Gearboxes with heavy reinforcing in the geardrive area behind the trigger, may require the removal of some of the reinforcement.
