Azgunguy's Review of Obsidian Arms AR-15 Firing Pin Retaining Pin

I picked these up due to my new maxim defense PDW coming with a retainer that was deformed from the factory due to being forced in. Having several spare pins is a great idea, I will keep a couple in my range kit and at home in my spare parts kit.
