D2 Rev. 2 – Enhancements Driven by User Feedback

Experience the next level of HPA with PULSAR D2 – an advanced evolution of the D version. Built on years of real-world feedback and technical refinement, PULSAR D2 redefines what an HPA engine can be. Designed for maximum performance, unmatched reliability, and effortless installation – even for users with no technical background. Engineered to operate at very wide range of pressures, the D2 delivers energy outputs as low as 0.5 J and as high as 3.6J, all without needing to swap to a lower-flow poppet at reduced power levels.

At its core is a completely reimagined poppet design combined with a larger compression chamber, ensuring a perfect air delivery profile, rock-solid stability. This translates to perfectly spun BBs and pin-point accuracy across a wide range of hop-up buckings. A centrally mounted nozzle spring replaces the previous tappet plate spring, ensuring reliability and flawless BB feeding. On top of that, the engine operates more quietly.

PULSAR D2 HPA Engine (dual solenoid, closed-bolt) with TITAN II Bluetooth® EXPERT– thanks to optical sensors combined with HPA technology, you get an absurd trigger response never before seen in airsoft. Get insane muzzle velocities ranging from 250-650 FPS & ROF from 1-40 RPS for CQB, assault, and sniper replicas. Closed-bolt and the innovative feed system guarantee you a straight and repeatable BB trajectory even in full AUTO – every time.

Engine calibration has never been easier – PULSAR D2 & TITAN II Bluetooth® is introducing innovative cycle synchronization automation. The most advanced and user-friendly GCS app lets you access a multitude of settings and configurations like binary trigger, trigger sensitivity, ROF – live via Bluetooth®. You can even use a remote trigger on your smartwatch. Install the world's smallest and most advanced dual solenoid valve HPA engine in replicas where previously not possible due to size constraints. Choose one of the five nozzles included or use a regular AEG one. Take your HPA replica into the future!

The D2 engine merging the best of both AEG (like off-axis resilience and enhanced BB spin) and HPA systems.

What makes PULSAR D2 a class above?

Accuracy. Versatility. Compatibility.

PULSAR D2 is unrivaled thanks to the following combination:

• Simple design
• Innovative automatic synchronization of the nozzle movement cycle enables easier calibration – no need to fire thousands of rounds to achieve good FPS results and stable BB trajectories
• Due to its innovative BB feed system and closed-bolt mode, it is definitely less sensitive to replica and assembly quality
• Razor-sharp accuracy of the system – no unstable hop-up system symptom like in other HPA systems
• Seamless integration & compatibility with the most advanced optical ETU/FCU TITAN II Bluetooth® for a synergy effect
• High tolerances eliminating the mid-cap syndrome
• Compatibility with any AEG nozzles
• Zero nozzle wobble resulting in stable FPS when paired with GATE AEG nozzles, which translates into stable FPS and no mid-cap syndrome
• No FPS drops on AUTO relative to SEMI mode at high RPS – up to 40 RPS with no FPS drops

🔁 Central Nozzle Return Spring

A centrally positioned return spring ensures perfectly symmetrical nozzle movement, reducing vibration and wear. This means greater precision, especially during high-speed firing cycles.

🔧 Wide Pressure Range. One Poppet. Zero Hassle. (60–140 PSI)

With a completely reengineered valve system and innovative dual-flow poppet design, PULSAR D2 delivers consistent, high-performance operation across a broad pressure range – from 60 to 140 PSI – using just one universal poppet.
No more part swapping. No more tuning headaches.

🔗 Seamless Integration with TITAN II Bluetooth® EXPERT

• Auto Cycle Sync – effortless calibration, no guesswork.
• Live tuning via GCS App – adjust trigger sensitivity, ROF, fire modes, and more – even from your smartwatch.
• Unmatched trigger response – thanks to optical sensors and dual solenoid HPA tech.

📐PULSAR D2 supports standard AEG nozzles

As with the previous version, the PULSAR D2 set includes five CNC-machined nozzles in different lengths. Additionally, it supports standard AEG nozzles, giving you the flexibility to use the one originally supplied with your replica.

💨 Optimized Airflow System

Redesigned internal channels and poppet geometry reduce flow resistance, ensuring smoother, more efficient air delivery. The result? Cleaner shots, better consistency, and improved air efficiency.

Note: gearbox is NOT included.
