Due to the industry growth and abundance of barrel contours available, PF has contracted barrel purchases of the most common length and profiles. Rifle Barrels are exclusively made from high quality 416R Stainless Steel. Contours, Fluting and Black Teflon coating are used on various models and can be seen on our rifle page. Special requests for barrel lengths and finishes depend on availability. Special requests and special orders will increase lead times. The lists of availability barrel for custom builds will be sold in the order that the deposit for a rifle build was received.
