GATE PULSAR D HPA Engine

GATE PULSAR D HPA Engine – Closed-Bolt Innovation for Next-Level Airsoft Performance

The GATE PULSAR D HPA Engine is a groundbreaking advancement in airsoft technology, combining high-end performance, user-friendly design, and precision engineering in a compact, dual-solenoid format. Designed for serious airsoft enthusiasts and competitive players, the PULSAR D delivers consistent FPS, smooth performance, and razor-sharp accuracy. Whether you’re running a CQB build, DMR, or a full-blown HPA sniper platform, this engine is engineered to elevate your game.

Closed-Bolt Precision with Cycle Synchronization

At the heart of the PULSAR D lies its closed-bolt design and innovative BB feed system, delivering unmatched shot consistency. Unlike traditional HPA systems that suffer from unstable hop-up symptoms and FPS drop-offs, the PULSAR D keeps your shots tight, accurate, and stable—even in full-auto at up to 40 RPS. This makes it ideal for players who demand reliability and accuracy in high-intensity skirmishes or competitive scenarios.

The real standout feature is its automated cycle synchronization, which ensures the perfect alignment of nozzle movement. You no longer need to fire hundreds or thousands of rounds just to fine-tune FPS stability. Instead, this engine calibrates itself intelligently, saving time and ensuring dependable performance right out of the box.

Compact & Versatile Design for Tight Builds

As the smallest dual-solenoid HPA engine on the market, the PULSAR D fits in replica platforms where larger HPA systems simply can’t. It opens up possibilities for high-performance builds in even the most compact AEG bodies. The package includes five AEG-compatible nozzles, and it’s also compatible with standard AEG nozzles, allowing for complete customization based on your build’s needs.

Stable FPS & Zero Wobble Performance

One of the common issues plaguing HPA systems is the dreaded “mid-cap syndrome”—where BBs fail to feed properly or FPS fluctuates. The PULSAR D eliminates this entirely. When paired with GATE AEG nozzles, it offers zero nozzle wobble, translating to extreme FPS consistency and enhanced feeding reliability. Whether you’re tapping in semi-auto or dumping rounds in full-auto, your gun will perform at peak levels with no FPS drop-off—even at 40 RPS.

Extreme Control via TITAN II Bluetooth® (Not Included)

When paired with GATE’s TITAN II Bluetooth® MOSFET (sold separately), the PULSAR D becomes an even more powerful tool. Use the GCS app to customize your trigger sensitivity, rate of fire, fire modes (including binary and burst), and even connect your replica to a smartwatch for remote firing capabilities. This level of control is virtually unmatched in the HPA world.
