The HW4 Premium series is based on a further developed version of the Lonex Osiris Receiver. The very robust and thick-walled receiver has now been expanded to include a quick spring change system and other smaller features. In addition to the European-made Begadi CORE, the other internals come from Lonex, Tienly, Maple Leaf, FPS Softair and Retro Arms - in other words, only components from renowned manufacturers from Taiwan and Europe are used. The HW4 Premium closes the gap between the former HW4 Classic and the HW4 Deluxe and thus offers an optimized price/performance ratio.
The development and production work on the HW4 Premium began during the Covid19 period and due to the generally known delays & restrictions associated with Covid19, the completion of all components and consequently the release of the HW4 Premium has been delayed. Looking at the Begadi range at the product launch of the HW4 Premium in early 2023, it would also have been possible to install other components in some cases - however, some of these were not yet on the market during the development phase of the HW4 Premium. With the knowledge that all the components installed are coordinated and of good quality, it seemed more sensible to start the setup as planned, as all the components installed fully fulfill their purpose even from today's perspective

Receiver:
The very robust and thick-walled Osiris Receiver has been revised by Lonex. It is now possible to change the Springs directly via the Stock Tube. The wiring of the EFCS now runs inside the Stock Tube, which means that it is no longer necessary to remove the plug during disassembly. Fire Selector, Bolt Catch and Mag Catch can be used on both sides.
Quick spring change system:
The Receiver has been equipped with a spring change system by Lonex. All you have to do is unscrew the Stock Tube and the Springguide can be removed by loosening the thick steel pin to the rear. It is not necessary to dismantle the Gearbox. If you lose the pin, you can find replacement pins here
Information on storage:
Always disconnect the battery from the gun when it is not in use! Otherwise your battery can be discharged by the continuous monitoring and thus be damaged
Information on the magazines supplied / delivery condition:
Lonex sends the magazines lying on top of each other in the box, without separating material between the 2 magazines. In rare cases, the magazines may rub against each other during transportation, resulting in slight marks.

Additional information on the warranty + Core:
The 4-year warranty mentioned above refers to the complete Semi AEG when the CORE Mosfet is installed, not just to the function of the Begadi CORE. However, this is the prerequisite for this extended warranty. If, for example, a different Mosfet is selected in the bookable special options in the Mosfet area (i.e. you ask us to remove the CORE and install a different Mosfet instead), the warranty is reduced from 4 years to the usual 2 years. In this case, the removed Core will not be included in the delivery but retained. Normally, we always include removed components in the delivery, but this is expressly not the case with the CORE - the CORE is only delivered in an installed state
