The Quarter Circle 10 GSF lower receiver is, quite simply, the finest pistol-caliber AR platform available. Precision milled from 7075 billet aluminum, each one of the receivers is hand-inspected at every stage of manufacture to ensure precision and quality. The GSF lower was designed from conception as a dedicated pistol-caliber receiver built around the Glock small frame magazine. Whether you shoot 9mm, .40 S&W, or .357 Sig, the GSF is up to the task of delivering rounds on target with more accuracy and power than a handgun, all in a package that is tighter and easier to control than a rifle-caliber firearm. Form and function play equal roles in the design, and the GSF not only runs like clockwork, it looks the part.
