lost M4/m16 carry handle's nut
Hello everyone. After yesterdays outdoor game, I lost one of the two nuts that holds my m4 carry handle. The chance of my finding it back is nearly impossible so I decide to get a new one.
Does anyone know what size of nuts do I need? Also is it possible to order the original one? I don't mind buying something like a wing nut, but I do want my m4 to look stock.
Any info is welcome.
