Forward Controls Design - SIG MCX Enhanced Mag Release Button - EMR-MCX

The Forward Controls Design SIG MCX Enhanced Magazine Release Button (EMR-MCX) is FCD's drop-in enhanced magazine release designed specifically for the SIG Sauer MCX and MPX rifle platforms. The EMR-MCX replaces the factory magazine release button with an enlarged, textured profile for faster, more positive magazine changes under stress — without requiring users to break their firing grip. Machined from billet aluminum to FCD's exacting tolerances and finished in hard coat anodize, the EMR-MCX is a direct drop-in replacement for the factory SIG MCX/MPX magazine release button requiring no modification to the receiver.
