There's DEFINATELY something wrong if the upper one touches the sight. OR do you mean it touches the foresight PROTECTOR part? Make sure that the RING, retaining, rear hand guard is right back against the body and that the stepped part of the front of the handguard aligns with the recess in the stock fore-end. Apply the same criteria to the rear part of the front hand guard. If it is still too long and touches the foresight protector then there's not too much you can do at the front so I suggest that you carefully trim the rear of the front handguard. THere's loads of meat there to play with.
