BAD-EMC-IC Enhanced Magazine Catch

• Process: Investment cast (mil-spec comparable process)
• Material: 8620 heat-treated steel
• Finish: Black phosphate
• Construction: One-piece design (not two-piece)
• Design: Lightweight fluted profile
• Threaded pin length: Shorter to reduce installed button profile on solid-face buttons
• Compatibility: Works with mil-spec magazine release buttons and enhanced buttons (BAD-EMR, BAD-EMMR, etc.)
• Weight: 0.25 oz (vs. 0.32 oz typical mil-spec)

Button Option A: BAD-EMR (Enhanced Magazine Release) – Black

Precision CNC machined from billet 7075-T6 aluminum (not 6061) with a black anodized finish, the BAD-EMR features a fully solid “V”-shaped face with horizontal serrations (no through-hole). The concave V-groove self-centers the index finger for consistent engagement, while the serrations improve traction during activation and help minimize drag during finger retraction. A lightweight, skeletonized rear offsets weight from the solid face, keeping overall mass comparable to a standard mil-spec button.

• Material: 7075-T6 billet aluminum
• Finish: Black anodized
• Face: Solid V-groove with horizontal serrations
• Fit: Compatible with lower receivers that accept mil-spec magazine release buttons
• Development: Product developed in conjunction with Forward Controls Design

Button Option B: BAD-EMMR-L-B (Enhanced Modular Magazine Release – Large Finger Pad) – Black

CNC machined from billet 7075-T6 aluminum with a black anodized finish, the BAD-EMMR uses a patent-pending three-sided dovetail finger-pad attachment system for strength, a clean uninterrupted pad face, and a lightweight, low-profile package. The interchangeable pad system enhances ergonomics and ease of operation without requiring the shooter to shift grip position—ideal for users who want modularity and a refined control surface.

• Material: 7075-T6 billet aluminum
• Finish: Black anodized
• Mechanism: Patent-pending three-sided dovetail finger pad attachment
• Ergonomics: Interchangeable pads for improved feel and control
• U.S. Patents: US 9,518,792 and US D779,620

Compatibility Notes

• AR15: Designed around mil-spec AR15 magazine release interfaces.
• AR10 / .308 platforms: Due to platform variances, fitment can vary by receiver pattern.
• Important: The magazine catch noted here will not work with .308 receivers.
• Note: Due to variations in AR308 platforms, the PK2 (EMMR) may not work with all receivers; a known compatibility issue exists with Aero M5 receivers.
