BAD-EMR (Enhanced Magazine Release) for the AR15/AR10.

• Precision CNC Machined for billet 7075-T6 Aluminum (not 6061) in an anodized BLACK finish, the BAD-EMR features an unique, fully solid "V" shaped button face with horizontal serrations (no through hole).
• 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 skeletonized 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 (approximately 0.002 lbs). BAD-EMR is compatible with all lower receivers that accepts mil-spec magazine release buttons.
