What this lightweight forend is and what the attachment system is?
I looked at Harris Bipod adapters, and there's several types, but the following advice probably could be adapted to other than M-LOK mounts.
M-LOK screws can be filed or ground to make them shorter, up until they'd be flush with their nuts when tightened. On M-LOK or keymod, the limiting factor is going to be the thickness of your nuts when properly mounted -- or rather the thickness of the portion of the nut that's on the inside of the handguard.
I had to do this to mount picatinny rail sections on my slimline M-LOK handguard over my Beowulf barrel. I used a motorized grinding wheel to take off most of the material while holding the screw head with Vice Grips pliers, then used a bastard to remove burs, then a second cut or finishing file to smooth it out. Having shorter screws complicates the mounting process a bit, but if you grind M-LOK screws enough, the protrusion inside the handguard should be a under .250".
