Hammer-Forged & Mil-Spec Hardened To Resist Surface Wear

Stripped bolt is hammer forged and machined to final dimensions from 8620 carbon-molybdenum-chrome steel to U.S.G.I. specs to handle the rigors of competition or combat operations. After machining, bolt is heat-treated  using an advanced process that gives it substantially greater surface hardness than Fulton's first generation bolts for exceptional wear resistance and superior core strength. Comes with roller and roller retainer already installed.
