Small Parts

This collection is where you’ll find small parts for Gibbz Arms uppers, including latching charging handle assemblies for our side-chargers, bolt carrier doors, and of course, Gibbz Arms enhanced cam pins. We recommend changing the standard cam pin in your bolt carrier group to one of our enhanced versions in order to ensure fluid, reliable operation. Using the standard cam pin can cause the action to lock up in the upper. With this simple swap, our side-charging uppers are compatible with effectively any mil-spec BCG, and many custom bolt carrier groups as well.
