- For Version 2 gearboxes
If you want to turn your M4, SMG-5, G3 or other V2 gearbox-equipped platform into an advanced space gun, the Double Eagle FALCON 2.0 Programmable MOSFET for V2 Gearbox should do the trick! This is the same FALCON EFCS system installed in Double Eagle's superb M90x range, including the UTR45, UTR556 and AX//15 rifles. Once installed, the FALCON offers a wide range of programmable fire mode options along with adjustable trigger sensitivity and the usual improvements in rate of fire and trigger response a MOSFET provides.
Available fire modes include 1-5 round burst, binary trigger (fire on trigger pull and on release), and 3 levels of trigger sensitivity, from a super short hair trigger to a more realistic full trigger pull. The FALCON will also warn you of any electrical anomalies by vibrating your motor 3 times and cutting off power to protect itself and will also cut power if your battery is running too low, indicating with 5 motor vibrations. The only thing the FALCON doesn't do is shoot the AEG for you!
- Enlarged contact surface
- Bridge or Flat styles
- Fits most Airsoft AEG HOP-up units
If you seek more accuracy or range from your AEG, the Prometheus HOP-up Tensioner for AEGs will help you achieve it! Supplied as a pack of two tensioners, you can choose between a "Bridge" style design with a central groove designed to reduce side-to-side deviation and thus, enhance accuracy, or a "Flat" style design intended to achieve maximum range. The contact surface provided by this HOP-up nub (another word for tensioner) is far larger than the standard, resulting in a stronger backspin effect and extended range with heavy-weight BBs.
The two tensioners included in the set are of different colours; one purple and one black. The purple tensioner is made from softer rubber, designed for sub-350 FPS builds and the black one is slightly harder, ideal for 350 FPS and above, making it the perfect tensioner for an AEG DMR. Compatibility-wise, these tensioners should fit almost any Airsoft AEG HOP-up unit but as always is the case with internal upgrades, we only recommend these for experienced techs and those who know their way around AEG internals. If accuracy and range is your objective, the Prometheus Bridge HOP-up Tensioner for AEGs belongs in your build!
