    KZ Benelli Extension Tube

    Solid construction, excellent fit, and finish matches the barrel. Good alternative to buying the full size Benelli magazine tube.

    Does the job.

    It does what is says, but the finish is really glossy. I took a dry Brillo pad to scuff it up and painted it with flat black Rustoleum high heat grill paint, matches the barrel finish almost identically. All and all it's a great product, definitely worth the money.
