Mark Serbu demonstrates the flame hardening process for the ejection port edge of a BFGA receiver. This technique uses an oxy-acetylene torch to heat the steel to its austenitization temperature, followed by rapid quenching in water. The purpose is to harden the edge, preventing it from bending or dinging when large caliber casings are ejected, thereby increasing the receiver's durability.

This guide details the process of sporterizing a Mosin Nagant by shortening the barrel and removing the rear sight base, as demonstrated by an expert gunsmith. Key steps include precise barrel measurement, cutting, and squaring the muzzle using specialized Brownells tools powered by a Milwaukee drill. The process emphasizes creating a professional 11-degree target crown for accuracy and safely removing the soldered rear sight base with an oxy-acetylene torch.
