Hi Warbird,
Just wondering, does your handguard come with "hard points" or "wedges" on the inner wall of the handguard? (sorry don't know the proper name for it)
They are for fastening onto the sockets that sit right beside the battery compartment (plz see your own pic above - to the left is the '=' shaped socket)
Cuz without these the handguard wobbles and twists off the centre line after a while, as what happened to my JG K handguard.
Many thanks
