Replace CA M15A4 Handguard

[Lotech]

Hello All,

I have a CA M15A4 Carbine. I would like to remove the plastic hand guard and replace with a metal RIS. For those who have done this, please let me know the make and model of any conversion kit you used. I would like this to be as easy as removing the plastic handguard and replacing with the new one. I for sure do not want to get out a grinder and alter the AEG.

Thanks for your help.
