combat arms lightsaber mod

hey the lightsaber works good and right click is really fast but in the youtube video combat arms lightsaber mod he puts the lightsaber down and then when he wonts he presses a button it pops up again and owns some more people wats the key to make it go down and key to make it go back up

i assume u just switch weapons... i doubt he configured a key into it...

Yes: It could be his pistol or a specialist weapon he redid.
