This also isn’t a normal small frame .308, it’s smaller! The Revolution 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. This is truly an AR15 that shoots in .308! Weighing in at 7.3 lbs.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.
