BAD-EMMR by Battle Arms Development

The BAD-EMMR is a lightweight, low profile, modular magazine release for the AR-15 and AR-10, recently released by Battle Arms Development. Its expanded finger pad provides an enlarged, uninterrupted, contact surface that gives the user a positive tactile feedback resulting in fumble-free operation.  One of its outstanding features is its modular design, allowing its users to use an array of finger pads depending on personal preference or operation. The EMMR’s 3-sided, precision fit, solid, dovetail attachment interface simplifies its locking mechanism – a feature that makes it stand out from the rest of its competitors. This translates to a wiggle-free, tight tolerance, slop-free fitting between the magazine release body and finger pad. The dovetail attachment interface also removes the stress away from the screw; this allows a single, scaled down, set screw to be used as opposed to the typical two large steel screws.

One of the great things I like about the EMMR is its swept-down angle, making it compatible with KNS anti-rotation pins.  Another great feature is its flush, low-profile design on its three sides. Three sides of the finger pad are flush with the magazine release body which makes it compatible with a variety of lowers. In particular, the lowers with ambidextrous bolt release where the 12 o'clock position of the magazine release fence is almost touching the magazine release. Oversized magazine release buttons by other vendors will crash and interfere.

In my opinion, the BAD-EMMR is the quintessential enhanced magazine release currently out in the market.

The BAD-EMMR is available in anodized red, black, and clear/silver, in medium and large finger pads.
