Ever get a rear handguard that has broken wood missing under the rear clip and the guard doesnt sit properly on the barrel?
I found a easy way to salvage it is to put a dab of high temp silicone gasket sealer under the handguard. Wipe in down so its 1/8 of a inch or so tall. Let dry and install.
The silicone will hold the handguard up off the barrel in its proper position
