UK airsoft players can now get this at Action Hobbies... "With SOCOM gear (in association with Madbull) as the main distributor, Daniel Defense releases their M4 AEG. This particular M4 features a full metal construction with full markings CNC milled into the body. The sweet looking DD M4 comes ready for use with LiPo batteries straight out of the box, and uses a Mosfet system. Coupled with a High Torque motor and a 7mm gearbox, the Daniel Defense M4 is capable of shooting up to 370fps straight out of the box.

As well as spare sights the gun also comes complete with the commando conversion so you can go for the CQB look."
