Got my AR today and I'm trying to mount an IWC TMC light mount onto the handguard except I can't seem to get the mounting plates to touch the screws through the heatshield.  Should I modify the heatshield it, or did I perhaps order the wrong hardware (I forget if I order hardware for Milspec or standard commercial handguard)?
Its a Delton Upper with just a single heatshield so I don't see why the screws shouldn't fit.|
EDIT: Just modified the heat shield a bit and its all good

Post pics. Even if it's just for us with standard Milspec hardware to see

Will post later, basically I cut off the mid parts of the first three heatshield holes so that the mounting plates would actually fit and reach the screw. 

Can't you just remove the heat shield, install the light mount, then replace the heatshield? Every set of standard plastic hand guards for an AR I have seen had the ability to remove the heat shields....

before you start cutting up things, longer screws are something you can find at most hardware stores.

I tried, but with the hardware installed the heatshields would not mount back in.
