The Patriot Ordnance MMR M-rail is an excellent choice if you want to upgrade your older, heavier POF rifle. This lightweight, free floating rail system attaches to POF uppers, and allows picatinny rail sections to be screwed to the bottom and sides of the handguard. This allows you to keep your handguard slim and lightweight, or you can customize the sections on your handguard for any additional accessories.
