80 Percent Arms - EMR (Extended Magazine Release) for AR15 and AR10/308
Our EMR is made out of 6061 Aluminum and comes in an anodized black finish. The EPA-EMR features an ergonomic button with a concave curve and horizontal serrations with a through hole in the middle. With a concave curve, the button's face provides excellent tactility and assists the user by self-centering the index finger when pressure is applied. The horizontal serrations are designed to reduce slippage when being used to effectively and smoothly release magazines. The EPA-EMR is incredibly lightweight yet retains a substantial feel with its material and slightly increase size in height. This EPA-EMR button is compatible with all AR-15 lower receivers that accept mil-spec magazine release buttons.
