This is another great addition to the Arthurian range of airsoft rifles. The Safir comes with a light weight skeletonised M-LOK rail giving it a great and unique look.
The 2021 model Excalibur Safir now feature an inbuilt MOSFET into the trigger board and a rotary hop unit. MOSFETs help protect the trigger contacts from being burnt out when using 7.4v or 11.1v LiPo batteries, increases the efficiency of the battery allowing for more shots per charge and increase the overall performance of the gearbox with a slight increase rate of fire and snappier trigger response.
One of the most impressive features of the stock system of the Excalibur Safir is the E&C quick change spring system. To change the spring, you simply need to unscrew the ring on the stock tube, rotate the stock tube 45 degrees and pull it off. After that unscrew the knurled screw at the back and the spring & spring guide will pop out. Be careful not to let it fly across the room, it may release with some force. Ultimately, this process only takes about 30 seconds.
