Forward Controls Design EMR-A Ambidextrous Magazine Release
EMR-A is a long in development ambidextrous magazine release for .223 and .308 AR receivers. Original concept and design was complete in 2015. After numerous changes to the mag catch geometry and lever shapes, final design was made into working prototypes in 2017, and first shown in public at Cola Warrior West III.EMR-A is an ergonomic ambidextrous magazine release. The placement of its lever is well thought out to closely mirror the magazine release button on the right side. The portion immediately below the bolt catch’s lower paddle has a lower profile to avoid interference, heretofore a common drawback of popular ambidextrous mag catches, it is also left smooth. The serrated length of the lever is split into a shallow V shaped serrations (80%) that conform to the curvature of the user’s finger, and straight serrations (20%) that form a natural index point, and provide additional traction.
A 10.9lb rated magazine catch spring is included with each EMR-A. Forward Controls Design long considered the standard magazine catch spring to be rather weak (rated at 8.3lb), accidental / unintended mag drops can take place if a user slings his weapon, and has gear and pouches on the vest. A stiffer mag catch spring mitigates these risks, thus it is an integral part in the EMR-A package.
EMR-A’s catch is made from CNC machined 4140 steel and black nitride coated, its lever is 7075 aluminum and Type 3 hard coat anodized. The roll pin has a shear strength of 800lbs.
Note: Due to the lack of standard dimensions for AR-308 platforms, the EMR-A may not work with all 308 ARs.
