The Revolution by Patriot Ordinance Factory (POF) is a .308/6.5 Creedmoor battle rifle that behaves like a 5.56. This is due to the fact that it uses a 5.56 bolt carrier along with other 5.56 parts such as a 9-position adjustable gas block, heat sink barrel nut, charging handle, and cam pin. These qualities result in a reduced weight and compact size. In addition, the Revolution features a fully ambidextrous receiver, E2 Dual Extraction Technology, Mission First Tactical furniture, and is available in Direct Impingement and Piston Driven systems.
