Lighter Design, Stronger Product
The Enhanced Series begins with our all new state-of-the-art forged upper receiver. The M4E1 (5.56) and M5E1 (.308) upper receivers are a one-piece design combining the rail's mounting surface with the upper itself. By machining the rail's mounting surface into the upper itself we have condensed the parts needed to mount a free-floated rail to a mere 8 screws. Since it is of the same forging as the upper not only is it a stronger system, but we are able to make even more lightening cuts to save weight and allow for more efficient cooling.
The Enhanced Rail
Choose a rail length and design that matches your shooting style. With how quickly rails can be changed out, we won't blame you if you get two. Choose from a traditional Quad Rail, Keymod Rail, or the new M-LOK from Magpul. Available in lengths 7" to 15".
Ease of Rail and Barrel Installation
Simply insert your barrel assembly into an Enhanced upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.
Near Seamless Rail & Upper Alignment
The E1 design removes the human element margin of error when it comes to not only installation, but also correct alignment and removing any gap between the upper and the rail.
The Enhanced Series Rails have a 1.8" inside diameter that will accommodate most muzzle devices and 1.5" suppressors. A perfect set up for your short barreled suppressed package.
