BAD-EMR Enhanced Magazine Release

  • Precision CNC Machined for billet 7075-T6 Aluminum (not 6061) in an anodized BLACK finish, the BAD-EMR features a unique, fully solid “V” shaped button face with horizontal serrations (no through hole).
  • The concave V-Groove button face offers an excellent ergonomic feel and self-centers the index finger as pressure is applied.  The horizontal, parallel serrations help 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 accept mil-spec magazine release buttons.

  • Ambidextrous Safety Compatible – The Enhanced Takedown Pin (BAD-ETP) head design does not obstruct the use of the right side ambidextrous safety selector lever.
  • Extended Pin Tips (+0.030″ over mil-spec) – Added tip length noticeably aids in starting/pushing the pins out from the left side of the receiver, without undue protrusion.
  • Bullet Tip Guide – Cone shaped recess at both pin tips prevent accidental bullet or tool slip and reduced the chance of scratching/damaging of the receiver.
