Inside Sniper Rifle Barrel Manufacturing: The Secret Precision Process

A flaw thinner than a human hair inside a rifle barrel can move a bullet inches off target at 1,000 yards. Go inside precision sniper-rifle barrel manufacturing to see how certified specialty steel becomes a drilled, rifled, stress-relieved, hand-lapped, inspected, and proof-tested barrel. We examine cut rifling, button rifling, hammer forging, microscopic quality control, and the final accuracy tests that expose imperfections no shooter can see. Every cut, groove, and micron matters.
