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.
Any orders containing lower receivers require a verified FFL dealer to make the transfer.
Lower receivers will not be shipped until QC10 has your dealer's license on file.
Please contact your desired dealer about sending us a copy of their license.
