    Nitride vs chrome lined bore and chamber comes down to a choice between what you most want to protect from wear/corrosion.

    Bore/chamber protection? Chrome lined.

    Complete protection of all internal/external areas of the barrel? Nitride processed.

    Combined with a 4140 or 4150 barrel alloy you end up with a stiffer barrel and a harder surface using a competent Nitride process.
