The TACTICKER is compatible with ASTER V2, ASTER II V2 or TITAN II V2 MOSFETs but won't work with standard trigger contacts or the original Gate TITAN MOSFET. If you love the feel of a GBBR trigger and want to give your AEG the same energy, the Gate TACTICKER Realistic Trigger System will do just that!

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!
