The Enhanced Magazine Release-Continuous Serrations 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-HC has an uninterrupted surface and serrations, its taller profile makes it easier to press and is only 0.04 taller than the factory magazine release button. When installed, the EMR-HC has a 0.08 protrusion above the mag release button fence on most forged receivers. Due to the EMR-HC's installed height which protrudes 0.08"" over the mag release fence when installed (only 0.06" or 0.07" of the magazine release button travel is needed to drop a magazine), EMR-HC is recommended for 7.62mm ARs only, though it does work on 5.56mm ARs and M16s. For defense and duty ARs and M16s, please use Forward Control Design’s EMR that has only a 0.01" protrusion over most forged receiver magazine release fence. For .308 ARs, the EMR-HC's taller profile will allow you to use AR15/M16 spec mag catch and ambidextrous mag catch/release. An EMR-HC installed on a .308 AR will not protrude over the mag release fence.
