The FosTech Stealth Raptor rifle in 5.56mm and OD Green finish (brand part no. ST-RPR-GR5DH2-S21MS) is built from FosTech’s premium billet line, machining the upper and lower receivers and Mach-1 handguard from a magnesium-aluminum alloy that cuts weight by roughly 33% while adding about 30% more strength than standard aircraft-grade aluminum. FosTech pairs the 16-inch Faxon Gunner-profile barrel with a FosTech Low Mass bolt carrier group for faster cycling and reduced felt recoil, and rounds out the build with a FosTech Sabre Comfort Grip, Anti-Walk trigger pins, and an adjustable FosTech Tomahawk stock. An Echo AR II trigger, one included 30-round magazine, and a plastic carry case complete the package. Among AR rifles, this Stealth Raptor configuration favors shooters who want a lightweight billet AR without sacrificing strength.
