Forward Controls Design EMR-A (Serrated)
EMR-A is a long in-development ambidextrous magazine release for .223 and .308 AR receivers.
The 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. We refer to the design as Multi-faceted Control Surface, the difference MCS makes has to be felt to be fully appreciated.
A 10.9lb/in magazine catch spring is included with each EMR-A. We've long considered the standard magazine catch spring to be rather weak (at 6.85lb/in), 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.
The 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.
EMR-A's lever pivots on the receiver.
EMR-A needs to be removed before installing / removing the trigger. EMR-A is installed and removed in the same manner as a factory mag catch.
Please wear eye protection while installing EMR, EMR-C, and EMR-A with the 10.9lb mag catch spring!
EMR-A is incompatible with Geissele's Maritime Bolt Catch without removing material from either the top of EMR-A's lever, or the bottom of Maritime Bolt Catch's lower paddle. The close proximity of these two control surfaces makes this combination less than ideal.
EMR-a is incompatible with KNS' Gen 2 Pins, but will work with Gen 2 Mod 2 and JJ Pins.
