AGL Defense will be introducing the Ergonomic Modular Rail (EMR) system at SHOT Show 2014. The EMR was developed as a lightweight, ergonomic, and modular option for all mil-spec AR-15 rifles.
The EMR forgoes M1913 rails and instead utilizes easy to install accessory rails that are 3D machined to fit the contour of the EMR. These rails can be secured at both the 45 and 90 degree quadrants, making them ideal for users that need to mount their sights, lights, or lasers at an offset angle. The rails are secured to the EMR via steel slide nuts that can be replaced if lost or damaged by cross threading. The EMR also features integrated quick disconnect (QD) swivel attachment points, further reducing the overall weight of the system.
The EMR is machined from aircraft grade aluminum. It is mounted to the upper receiver via a 2.25″ barrel nut also machined from aircraft grade aluminum and hard coat anodized for a durable surface. The EMR also includes a proprietary ALG EMR barrel nut wrench. The rail secures to the barrel nut via 6 mounting bolts which also allow for easy removal and reattachment.
The EMR will be available in 10″, 12″, and 13″ lengths. It will be initially introduced with Black anodizing, however Grey will also be an option.
Update: We received this info from ALG Defense. Because the EMR was designed to be a lightweight system, there are currently no plans to make available a continuous top rail. The Geissele SMR MK series of rails would be the best option for individuals that would like to add a DBAL, laser, or top mounted lights.
