Battle Arms Development Enhanced Magazine Release V-Shaped Black Anodized 7075-T6 Aluminum for AR-15, AR-10 BADEMRB

The concave V-Groove button face offers excellent ergonomic feel and self-centers the index finger as pressure is applied.  The horizontal, parallel serrations helps slippage in the vertical orientation while minimizing drag in the horizontal direction for finger retraction.

The BAD-EMR also features a lightweight skeletonize back to offset the weight gained from the fully solid button face and slightly increased height to equal the weight of the standard mil-spec magazine release (approxmiately 0.002 lbs).  BAD-EMR is compatible with all lower receivers that accepts mil-spec magazine release buttons.
