Wolverine Airsoft has reinvented the HPA engine with their newest SMP, the INFERNO engine. It's incredibly simplified, modular design with minimal moving parts means less maintenance and better performance. The INFERNO engine is Wolverine's center-line air nozzle version for version 2, 3, and M249, and is entirely parts-compatible with it's sister line of SMP engines, the HYDRA line, that have offset nozzles for other airsoft guns.
This edition comes with the premium FCU that controls both the dwell and rate of fire by turning 2 easily adjustable knobs. A Version 3 Trigger board replaces the stock trigger group and provides lightning fast trigger response compared to stock.
