The EMR features a slightly curved button surface to fit the natural curvature of your finger. The form fitting curve, along with horizontal serrations, create a self centering surface that inhibits the finger's vertical movements. The EMR has a milspec through hole for the magazine catch's shaft, and is only 0.02" taller than the factory magazine release button. When installed, the EMR has minimal protrusion above the mag release button fence on most forged receivers.
Made from 4140 Steel.
Proudly made in the USA.
