I just took the rifle down and looked inside the forend again. Appears to have proper contact in the receiver area, bushing is correct height/length, knox has correct amount of contact, barrel is not touching the top handguards, no barrel contact except for the ring and at the very end of the forend. Correct pressure against the muzzle end of the forend. Barrel is near new and clean (I have 80 rounds through it currently) but I ran a bore snake through after each shot for the first 10, then cleaned with a brush and patches, repeated twice.
