Specifications and Build
The B.A.D. AR15/M16/M4 Aluminum Enhanced pin set is machined from aluminum and finished with Flat Dark Earth Type III hardcoat anodizing. That anodizing adds hardness and corrosion resistance while giving the pins their warm FDE tone.
Each pin is manufactured to exacting standards for a proper Mil-Spec fit, so it works with standard detents and springs. The smooth anodized surfaces help reduce friction during takedown and reassembly.
The lighter aluminum construction is the headline benefit, shaving mass right at the front and rear of the lower.
Practical Use, Care, and Compatibility
Installation is a direct swap for standard takedown and pivot pins, and the enlarged heads make hand disassembly quick. No tools are needed to break the rifle down for cleaning.
The hardcoat anodizing resists wear and grime, so a simple wipe keeps the FDE finish sharp. Avoid dragging the pins across grit, and they will look great for years.
