M4 Anti-Walk Pin for M4/M16 metal frames. What makes this pin so special is after it has been inserted into the receiver, as it is tightened down, the center section of the pin is pushed outward, ensuring that it cannot back out. Never again will you have to worry about your Tokyo Marui Next Generation M4 splitting apart unexpectedly during combat.
