This is a real steel project that we have been following, the AK50 being developed by Brandon Herrera, aka the AK Guy. The Firearm Blog got in touch with him to talk more about the project... "Brandon Herrera started The AK Guy several years ago and embarked upon a crazy idea, that of making a .50 BMG Kalashnikov rifle. The AK50 is still yet to come to fruition but what is really fascinating is the journey that Brandon took and all the trials and errors that happened along the way. Initially starting with CAD designs and eventually morphing into several prototypes, his experience is one that everyone can learn from."
