This isnt a stripped down rifle thats saving weight by making extra cuts or lacking the battle rifle features youre accustomed to. POF-USA worked Patriot magic into the Revolution by using a 5.56 bolt carrier and other 5.56 parts allowing for a shorter overall receiver size and reduced weight. This also isnt a normal small frame .308" its smaller! It features many 5.56 parts; such as charging handle, bolt carrier, cam pin, buffer, heat sink barrel nut, handguard, and 5-position gas piston operating system. The barrel extension, bolt assembly, upper, and lower receiver are the exact same size as those on an AR15. Weighing in at 7.3 lbs. the Revolution features their new Edge Handguard with four built-in QD mounts, and is packed with all youve come to expect from POF-USA.
