Barrett REC7 Gen II 6.8 mm Remington SPC 16in Tungsten Grey Cerakote Semi Automatic Rifle - 30+1 Rounds - The REC7 combines the familiar ergonomics of the AR style rifle with a revolutionary short stroke gas piston operating system to create a rifle that runs cleaner and more reliably than traditional designs. Unlike direct impingement firearms that release gas into the upper receiver, the REC7 piston vents excess gas forward at its patented chrome-lined, fluted gas block, resulting in cleaner, cooler, lower-maintenance operation. The black nitride coated gas block features two positions for suppressed or unsuppressed shooting, ensuring reliability of the shot and helping to avoid unnecessary wear from over speeding the action. It also allows the user to access the piston assembly for maintenance via the front of the rifle without requiring removal of the hand guard or barrel.
