B5 Systems Grip Plug – AR-15/M16 Cavity Insert (ODG)

The B5 Systems Grip Plug seals the hollow storage cavity found in many AR-15 and M16 pistol grips, preventing debris, moisture, and dirt from accumulating inside your lower receiver. This simple plug improves reliability in harsh field conditions while maintaining a clean interior without adding unnecessary bulk or weight.

Machined from durable polymer in Olive Drab Green (ODG), the plug press-fits securely into compatible AR-pattern grips with storage compartments. Installation is tool-free—simply insert and press until seated. Compatible with most AR-15 and M16 grips that feature bottom storage cavities, including many B5 Systems and similar grip designs.
