Redneck .32-20 Rifle from a No. 4 Enfield

This is an ingenious rework of a worn-out No. 4 Enfield. He basically cut the barrel off just ahead of the chamber, drilled out the chamber so the barrel could slide inside it, and secured it with setscrews. Then he used setscrews to chamber it for .32-20. Here he is shooting it: Wecsogging at its best!

Small Arms Cycle of Operations

This is a pretty good US Army training film that describes the basic parts of a weapon, and how those parts work.

DIY AR15 Firing Pin

This is pretty ingenious. A firing pin for an AR15/M16, made from a common nail. Since these nails are made from mild steel, I think I would want to harden it with Casenit carburizing compound; otherwise it would probably wear out pretty quickly.
