Fox Airsoft show the features of the update Elite Force Competition AEGs that now come with the M-Lok System... "Elite Force has come out with updated versions of their Competition series M4's now featuring an MLOK rail and only coming in a black/tan color combination. The internals get an update too featuring the programmable gearbox and straight trigger like the MCR model. This new MLOK M4 is available in CQC and CQB length models. Also at the time of this video, the older versions of these guns are still being offered in case you prefer a picatinny rail instead."
