Designed for a Coast-to-Coast Pump Shotgun but should fit other makes and models. The use of one of these caps prevents debris, dirt, and moisture from going down your barrel when not in use. Also protects the tip of the barrel from getting dinged up and banging into objects. Sold as a pair. The caps are made from vinyl so they are flexible, durable, and make a tight seal. All of my products are made and shipped from the USA. The color is black. I offer free shipping to the United States.
