Product Description:
The Redline N7 Gen2 is a Patent Pending HPA drop in cylinder replacement system. It is an updated version of our legendary N7. The very first single solenoid, true closed bolt HPA engine.
Like the original N7, the N7 Gen-2 uses a single solenoid, has a forward biased nozzle and fires from a true closed bolt.
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.
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 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:
1: Nozzle Dwell.
2: Semi Auto Max Rate of Fire
3: Full Auto / Burst Mode
4: Full Auto Rate of Fire
5: Anti Stiction Pulse
6: Selector position

The N7 Milsim ended up being the engine I purchased due to the lack of electronics and great price point. I was extremely impressed with how quick the install was, only taking 2 tries for flawless functionality. I did have to do some minor modifications to my gearbox (no dremeling, just had to take out a couple posts with pliers), along with the lines for the trigger mechanism needing to be shortened a little bit to reduce kinking. Once I got it in the gearbox, it was smooth sailing from there. The engine provides great perfomance on the field, and despite its fully mechanical nature, the trigger feel was more than acceptable out of the box. Overall, great product for my fellow battery-haters.

I have many guns and wanted to move to a fully mechanical system, the RedLine N7 did just that, even using a stock barral with it, the accuracy was very good, and the best part no batteries.

Originally bought as a backup gun but I am loving it and using it more than my other systems. Performance is not lacking either. Only downside is the sound and the whole double pop. Notably louder than other systems like the Kythera and jack. Cool engine!

I have now installed three of these in 3 different AEGs and can't say enough about how much I love these HPA engines. The first went into a VFC Colt Licensed Tan MK18 MOD1 Full Metal VR16, and the only issue was that the micro lines had been switched at the factory. One email and a very fast response from Redline later, it was up and running. The second went into a G&G CM16 Combat Machine, super easy and fast, turned that lightweight AEG into a lazer. The 3rd was an adventure. I used a Krytac Trident MKII SPR, which is not recommended by Redline due to the complexity of the inside of the gearbox shell. Well, I only found that out after gutting the gearbox, so after a few hours of grinding, fitting and refitting, it went in and worked flawlessly. Now I just have to wait and see how it performs on the airsoft field.....
