Redline Airsoft N7 Gen-2 Electro-Pneumatic HPA Conversion Kit For Version 2 M4
The Redline N7 Pnematic HPA Conversion kit is no ordinary cylinder engine that is a true closed bolt and single solenoid system. This means less hop-up placement issues thanks to improved air efficiency and consistency. After installing this engine, you can get away with no FCU tuning at all. This will prevent players who are just getting into HPA from struggling on how to use an FCU. Another unique feature the N7 provides is its air chamber that fills up according to the PSI on the regulator. This changes the way the BB propels instead of relying on the dwell of the solenoid. This engine is an easy drop in system and is now available at Airsoft Megastore!
