The QC10 receiver set represents the bare essentials for a quality pistol/carbine build.  The stripped lower and upper with proprietary parts form a solid foundation from which to completely customize a pistol or carbine.  Some customers purchase this kit as an upgrade to their existing platforms, while others try their hand at matching the performance of  a QC10 full build with other components. Regardless, the QC10 Receiver kit ensures the heart of the build is American.  Made for, not modified, with a connection to Texas that no one else can match.
