Information about the Begadi Modular Handguard:
With the new CNC machined Begadi Modular 10" Handguard there are no limits for the player when it comes to customization, we offer 5 different systems and colors here: M-LOK, Keymod, Picatinny (full), Keymod with double and single Picatinny. These rails are firmly screwed to the left, right and bottom of the handguard via 4 screws each and thus offer a variety of mounting options. Of course, the individual rails can also be mixed, for example, to use M-Lok on the left and Keymod on the right.
A video about the mounting can be found here . This system was developed and protected by Begadi. The corresponding certificate can be viewedhere
For all customers who already own a M4 model,
we offer the Modular Handguard also separately. (Art: 19920021)
Storage information:
Always disconnect the battery from the weapon when it is not in use! Otherwise, your battery may be discharged by the continuous monitoring and thus be damaged

Additional information about warranty + CORE:
The above mentioned 4 years warranty refers to the complete S-AEG, not only to the function of the Begadi CORE, if the CORE Mosfet is installed. However, the same is the prerequisite for this extended warranty. If, for example, a different Mosfet is selected in the special Mosfet options (i.e. you ask us to remove the CORE and install a different Mosfet), the warranty will be reduced from 4 years to the usual 2 years. Also, the removed CORE will not be included in this case, but retained. Normally we always deliver removed components, but this is explicitly not the case with the CORE - the CORE is only delivered in assembled condition
