how do you mod the Ares grenade launcher to fit the ICS L85

[Bluemonkey]

hey guys looking on how to fit the ares grenade launcher to the ICS L85

i got told to buy the gas block conversion kit and it will fit well that was a load of bollocks because it doesnt i've chilsed out part of the clip that came with the grenade launcher to make the clips fit but that hasnt worked as the barrel when its inside of the grenade launcher just drops down so it doesnt stay level so right now i'm pretty pissed of waisting money and for ICS for not making an L85 grenade launcher where they could of made some money but anyway.
