SHS Ergonomic Modular Rail EMR V1 12.5 inch for M4 AEG black

The Ergonomic Modular Rail (EMR) with M-LOK System was designed to be a cost effective, lightweight, ergonomic and modular option for the M4 Carbine. The EMR was also designed to do a good job in meeting the ten design specifications for a good M4 weapon rail. Instead of four sharp and jagged M1913 rails spaced at 90 degree intervals, the EMR is fully ergonomic, maintaining its comfortable rounded shape throughout the length of the rail. The rounded top allows the shooter to easily wrap his or her thumb over the top of the EMR as many shooters like to do with a forward grip. Accessory rails can be attached anywhere along the length of the rail in 45° intervals, including the standard 12, 3, 6 and 9 o’clock positions. The 12 o’clock rail will “co-witness” with the top of an M4 upper receiver for use with any front BUIS. The EMR also includes 2 standard non-rotating QD slots on either side of the rail.
