Note: For ported barrel builds, we recommend using black iron sights without any colored areas, fiber optic rods, or tritium vials in case of excessive sight fouling. Carbon can cover and stain your rings and the pressure and heat from the gas can damage the rods or vials. Norsso is not responsible for any damage caused by sight fouling.

    Awesome barrel

    Posted by Adam on Jan 12th 2024

    Ordered a whole slide and barrel for my m18 p320 and I can’t be more happy! The lockup is the best my m18 has seen from the factory sig upper and the Zev complete upper I had. The ports are done beautifully as well. Can’t wait to take it to the range! You won’t regret the quality.
