The patented EDGE Modular Railed Receiver is POF-USA’s crown jewel for precision and extreme rigidity. This is a two-piece upper assembly, with a free-floating monolithic handguard that interfaces directly to the upper assembly thanks to our upper’s reinforced backbone. This backbone is five-times thicker than standard flattop platforms. The suspended handguard keeps your accessories from weighing on the barrel and has more than 6 points of attachment to keep the rail from experiencing any movement under stress. Our Edge rail features full M-Lok compatibility and features 4 QD sling mount slots.
