    Gas block and gas tube

    Shipped in a protective plastic cylinder. They arrived in perfect shape with no scratch. The gas block looks as good aero precision nitride gas block. The gas tube is shiny stainless steel. The inside of the gas tube is smooth unlike others I’ve purchased from other store. Breek Arms is one of my go-to stores for parts. They have competitive pricing and free shipping.
