Patriot Ordnance Factory Revolution 308 Winchester 16.5in Black Anodized Semi Automatic Modern Sporting Rifle - 10+1 Rounds - California Compliant - The Revolution isn't a stripped down rifle that's saving weight by making extra cuts or lacking the battle rifle features you're accustomed to. We've 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 isn't 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 7.3lbs. the Revolution features our new Edge Handguard with four built-in QD mounts, and is packed with all you've come to expect from POF-USA. Fully ambidextrous billet receiver set, nickel plated carrier, 5-position adjustable gas piston, single stage match grade trigger, and more. With our triple port muzzle brake recoil management is not an issue.
