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

Reviews:
The following reviews show the Carbine version of the model. Technically, the Carbine version is identical to the version offered here, the differences are purely in the external appearance and the barrel length (rails, length etc.). For this reason, we have also linked the reviews of the Carbine version here.
