Notes from Manufacturer:
Due to the EMR-C’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-C 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 our EMR that has only a 0.01″ protrusion over most forged receiver magazine release fence.
For .308 ARs, the EMR-C’s taller profile will allow you to use AR15/M16 spec mag catch and ambidextrous mag catch/release. An EMR-C installed on a .308 AR will not protrude over the mag release fence.
