The .308 Revolution is an AR-15 that shoots .308! This isn’t a normal small frame .308, it’s smaller! It shares the majority of its components with our 5.56 rifles. The barrel extension, bolt assembly, upper, and lower receiver are the exact same size as those on an AR15. All Revolution Uppers features free floating barrels, four built-in QD mounts on our rail systems, and is packed with all you’ve come to expect from POF-USA. Fully ambidextrous charging handles, POF-USA bolt carrier, adjustable gas blocks, patented roller cam pins, and more.
