Aligned by design. Less time on the workbench.
HUSAR is a fully ready-to-use motor for platforms with V2 gearboxes. The engine is rigidly connected to the hop-up chamber, while clearance between the engine body and the gearbox lets it stay aligned with the barrel. There is no tedious engine alignment or trial and error with nozzle lengths. The nozzle is matched to the chamber at the factory to seat each BB precisely in the hop-up bucking.
Built for accuracy. Designed as one system.
HUSAR brings the bucking standard known from precision sniper builds to your assault rifle or DMR. The engine, EON VSR chamber and factory-matched nozzle form one integrated assembly. Chamber and VSR bucking included; choose a VSR barrel separately.
Precision that delivers. From the first shot.
HUSAR delivers 14 mm of nozzle travel, compared with around 7.8 mm in a standard AEG setup. We designed the engine and EON VSR chamber together around this extended travel to take fuller advantage of GBB/VSR buckings. Connecting an existing HPA engine to a VSR chamber does not automatically provide the same nozzle movement or matched system geometry. Chamber geometry and a factory-matched nozzle length also matter, ensuring the BB is correctly positioned in the bucking.
Choose the bucking profile and hardness to suit your BB weight and setup. The lightweight POM nozzle operates with low friction and resists wear.
Precision developed on the range.
HUSAR builds on the experience gained developing PULSAR S2 for PTX, through a programme of more than 47,000 shots. In comparable GATE R&D tests at 40 m, the move from V22 to V31 reduced average MOA by 53.9%. The best 50-shot group achieved 25.32 MOA and a SCORE of 87 with a barrel just 138 mm long.
We brought that experience into HUSAR: an HPA engine engineered for exceptional accuracy. The engine and included EON VSR hop-up chamber work together as one matched system.
Retract the collar. Disconnect the chamber.
The QD connection positions the engine and hop-up chamber relative to each other and keeps the nozzle aligned with the chamber. Freefloat mounting clearance reduces the influence of gearbox and receiver misalignment on the matched assembly.
Retract the QD collar towards the engine rear to release the lock. Then withdraw the hop-up chamber along the shared axis. To reassemble, insert the chamber and return the collar to the locked position.
