    Default 33/40 handguard screws

    finally sourced a original 33/40 handguard,
    picked up a pair of screws from an online vendor. Screws are non scalloped 33/40 re-pops.

    however screws are a hair too long, the bolt won't retract when the screws are in all the way. Rear one needs to be backed out about a turn.

    are there washers that were used from the factory under the screw heads? Thinking about hitting the screw with a grinder to shorten it up a smidge seeing how its not original.

    everything else on this gun is original and numbers matching (bolt MM) so i want to keep it as original as possible.

    Here are a couple pictures of the issue.
    You can see it’s about 2 threads too long.

    The length of the shaft is 39mm.
