  • Brushless motor
  • 27K RPM - Speedy!
  • For M4/AR-15, SMG-5, G3 & P90 AEGs

If you want to breathe new life into your AEG in the form of speed and torque, the Specna Arms BLDC Brushless Motor; Long is calling your name! The BLDC motor is the affordable option in Specna Arms' new brushless motor lineup, offering the same benefits as the top-end DARK MATTER™ motors with a more economical cast aluminium housing. This variant is the 27K option, offering 27,000 revolutions per minute, plenty for a high-speed build but also an asset to any DMR build requiring a high torque solution. 

Brushless Motors boast lower heat build-up, higher torque-to-weight ratio, improved reliability via reduced friction and significantly reduced operating noise when compared to conventional brushed motors. This, the "long shaft" variant is designed for M4/AR-15 derived AEGs, G3, SMG-5 and P90 AEGs and is a relatively simple install job, though you may need to reinforce other parts to cope with the impressive torque and speed delivered by the BLDC motor. 

If you're upgrading your M4, G3, SMG-5 or P90 AEG and seeking more speed for a higher rate of fire or more torque for a better trigger response and the ability to pull strong DMR springs, the BLDC Brushless Motor from Specna Arms is the ideal affordable option!

  • HPA Engine for V2 gearbox
  • TITAN™ II V2 HPA Version required
  • For M4/AR-15, SMG-5 & G3 AEGs

If you're done with AEGs and want to revamp your build for HPA, the GATE PULSAR D Dual Solenoid HPA Engine is a fantastic option. Designed for Version 2 AEG gearboxes, the PULSAR D is designed to work with a GATE TITAN™ II V2 ETU (HPA Version), giving you unlimited advanced programming options along with the bob on consistency, top-tier accuracy, killer rate of fire and wealth of tuning opportunities HPA builds are known to provide.

The set includes the complete engine but will require a V2 gearbox shell, V2 trigger and TITAN™ II ETU HPA Version to complete the build. When compared to the original and more affordable PULSAR S, the PULSAR D offers a higher FPS range, universal compatibility with AEG nozzles, less precision required in the assembly of the build and impressively high air efficiency, using only 0.7 PSI per shot on average at 90 PSI with a 0.8L air tank.

The PULSAR D also has the edge in accuracy and versatility over the simpler single solenoid PULSAR S, being suitable for any build objective, from CQB monster to DMR dominator. As with all internal upgrades, we only recommend this engine to those who are confident working on AEG and HPA internals, but if you're ready for the PULSAR D, you're sure to be impressed!

  • Polymer construction
  • Suits high-speed builds
  • Friction fitting & locking

Increasing the rate of fire on your airsoft rifle sometimes causes it to misfeed, resulting in dry firing. A sector gear delay will solve your feeding problems 99.9% of the time with a simple add-on.

This sector gear clip increases the time it takes for the air nozzle to cycle. Delaying the cycle improves BB feeding by allowing the air nozzle to be retracted from the hop-feed for a longer duration.

This tiny add-on could instantly transform your AEG if it has been suffering from firing issues.

Although this is designed to be a perfect fit, it is recommended that this be permanently fixed in place using superglue, after testing to prevent it from potentially loosening over time.
